C0710 on 2007-2010 Chevy Silverado 2500: StabiliTrak Light and Steering Sensor Fixes

What's Unique About the 2007-2010 Chevrolet SILVERADO 2500

On this generation of Silverado (GMT900), the C0710 code is a very common issue. GM has released multiple Technical Service Bulletins (TSBs) acknowledging problems ranging from unwanted stability system activation to simple connector issues. While the sensor itself is a frequent failure point, these trucks are especially known for poor electrical connections at the sensor due to fretting corrosion and excessive clearance in the connector, which can cause the same code and symptoms without the sensor being faulty.

Diagnostic Flowchart

Tap your situation to follow the diagnostic path that matches what you're seeing on this vehicle.

Symptoms You May Notice

• "Service Stability" or "Service StabiliTrak" message on the Driver Information Center (DIC).
• StabiliTrak/Traction Control indicator light is on.
• Unwanted brake application or engine power reduction as the system incorrectly tries to correct a perceived skid. [⭐ MANUFACTURER TSB — highest authority] Bulletin #PIT4322P.
• The StabiliTrak system is disabled.
• A pull to one side that requires the driver to hold the steering wheel off-center to drive straight, which can confuse the sensor.

Most Likely Causes

1. Poor Connection at the SAS Connector 🔴 High Probability GM TSBs #SB-10043887-2153 and #06-02-35-002B specifically call out fretting corrosion (dark smudges on terminals) and excessive clearance in the sensor's electrical connector, causing a poor connection and high resistance. The movement from using a telescoping steering column can accelerate this wear.
   How to confirm: Visually inspect the sensor's connector terminals for dark smudges (fretting corrosion). Wiggle the connector to see if it feels loose. TSB #SB-10043887-2153 explicitly states NOT to replace the sensor for this condition until the connector fix has been attempted.
   Typical fix: Disconnect the connector, clean the terminals with a dedicated contact cleaner, apply a small amount of dielectric lubricant (GM P/N 12377900), and secure the connector. The TSB also suggests adding an adhesive shim (Kent Automotive P/N P40100) to the connector to prevent movement. In some cases, a special clip (GM P/N 19179794) is installed to act as a terminal positive assurance (TPA).

2. Steering Angle Sensor (SAS) Failure 🔴 High Probability → Shop Steering Angle Sensor The sensor is a known high-failure item on this platform, with dealerships often keeping them in stock. It is a moving part that wears over time.
   How to confirm: Use a scan tool to monitor the live data from the steering angle sensor. As you turn the wheel, the angle reading should change smoothly and logically. If the value is stuck, jumps erratically, or shows an invalid voltage (e.g., less than 0.4V or more than 4.6V), the sensor has likely failed.
   Typical fix: Replace the steering angle sensor located on the steering column and perform a recalibration. This involves removing the lower dash panels and dropping the steering column for access. 🎬 Watch this step-by-step guide to replacing the sensor yourself.
   Est. part cost: $50-$150
3. Incorrect Steering Angle Sensor Calibration 🟡 Medium Probability → Shop Steering Angle Sensor The sensor can lose its calibration after a wheel alignment, battery replacement, or any repair involving the steering column or suspension. The system expects the sensor to read 0 degrees when driving straight.
   How to confirm: If the code appeared immediately after a relevant service, this is a likely cause. A professional scan tool is needed to access the EBCM and check the sensor's current center position.
   Typical fix: Recalibrate the sensor using a compatible bidirectional scan tool. The procedure is often called 'Steering Wheel Angle Sensor Learn' or 'Centering' and involves setting the straight-ahead position. 🎬 See how to perform the SAS calibration with a scan tool.
   Est. part cost: $0
4. Vehicle Modifications ⚪ Low Probability As per a GM TSB, modifications like suspension lifts, leveling kits, or significantly oversized tires can alter the vehicle's geometry and cause the StabiliTrak system to set a C0710 code. [⭐ MANUFACTURER TSB — highest authority] Bulletin #PIT4322P. The EBCM detects a mismatch between the steering angle and the vehicle's actual movement.
   How to confirm: Inspect the vehicle for any aftermarket suspension or steering components. The diagnostic process should start here if modifications are present. [⭐ MANUFACTURER TSB — highest authority] Bulletin #PIT4322P.
   Typical fix: The vehicle may need to be returned to stock specifications, or a specialized alignment and recalibration may be required to compensate for the changes. A recalibration is essential after installing a lift or leveling kit.
   Est. part cost: $0

Rare But Worth Checking

• Faulty Electronic Brake Control Module (EBCM): This should only be considered after the sensor, wiring, and calibration have been thoroughly checked and ruled out. It is an expensive part and rarely the cause.
• Wiring Harness Damage: Damage to the wiring between the SAS and the EBCM can cause an open or short, triggering the code. This is uncommon but possible, especially if other dash work has been performed.

Diagnosis Steps

1. Check for any vehicle modifications (lift kits, etc.) as per TSB #PIT4322P. If present, this is a primary suspect. [⭐ MANUFACTURER TSB — highest authority] Bulletin #PIT4322P.
2. Connect a scan tool capable of reading GM chassis codes and live data (e.g., Tech 2, Autel).
3. Read the fault codes from the Electronic Brake Control Module (EBCM). Note if C0710 is paired with C0455.
4. Navigate to the EBCM live data and monitor the 'Steering Wheel Position' parameter.
5. Turn the steering wheel from lock to lock. The angle should change smoothly and consistently. Jumps, freezes, or invalid readings point to a bad sensor or connection.
6. Perform TSB Connector Fix First: Locate the sensor connector at the base of the steering column. Disconnect it and inspect terminals for fretting corrosion (dark smudges).
7. Clean the connector terminals with electrical contact cleaner, apply a small amount of dielectric grease (GM P/N 12377900), and ensure a snug fit. Consider adding the shim or clip if looseness is apparent. Clear codes and re-test.
8. If the code appeared after a wheel alignment or battery disconnect, perform the 'Steering Wheel Angle Sensor Learn' procedure with the scan tool.
9. If the sensor data is still bad and the connection is confirmed good, replace the steering angle sensor.
10. After replacement, a calibration/learn procedure is mandatory.

Related Codes That Often Appear With This One

• C0455 — This code also relates to the Steering Angle Sensor circuit and is often caused by the same connector corrosion issue mentioned in TSB PI0639C.
• U2143 — This code indicates a loss of communication with the steering angle sensor module, which can occur if the sensor fails completely or the connector becomes disconnected.

Technical Service Bulletins (TSBs) & Recalls

• PIT4322P: Mentions unwanted Stability Activation and/or a Service Stability message with DTC C0710, advising to check for vehicle modifications first.
• SB-10043887-2153 (also PI0639A/B/C/D): Details a fix for C0710 caused by fretting corrosion in the sensor connector, advising to lubricate and secure the connector before replacing parts.
• 06-02-35-002B: Describes how telescoping steering columns can cause high resistance in the sensor connector, leading to code C0710, and provides a fix using a retainer clip.

Platform-Specific Known Issues

• TSB #PIT4322P warns that unwanted stability activation can occur, where the truck may apply brakes on its own due to this fault. [⭐ MANUFACTURER TSB — highest authority] Bulletin #PIT4322P.
• TSB #SB-10043887-2153 (revising PI0639) specifically calls out fretting corrosion on the connector terminals as a cause and advises against replacing the sensor until the connector has been serviced by cleaning, lubricating, and shimming it.

Mechanic-Grade Diagnostic Values

• Steering Angle Sensor Analog Signal Voltage (Wheels Centered) — expected: Approximately 2.5V. Failure: Voltage is stuck, erratic, or significantly different from 2.5V when wheels are straight. Using an oscilloscope may reveal dropouts during steering wheel rotation that a multimeter would miss.
• Steering Angle Sensor 5V Reference Circuit — expected: 4.8 - 5.2V between the reference circuit terminal and ground.. Failure: Voltage outside this range indicates a problem with the EBCM or a short/open in the wiring.
• Steering Angle Sensor Low Reference Circuit Resistance — expected: Less than 2 Ω between the harness connector and the EBCM connector.. Failure: Resistance of 2 Ω or greater indicates an open or high resistance in the ground circuit, which should be repaired before condemning the EBCM.
• Scan Tool Live Data - Steering Wheel Position — expected: Smoothly travels between approximately -550 and +550 degrees from lock to lock.. Failure: Value is frozen, jumps erratically, or does not correspond to the physical movement of the steering wheel.

Hidden / Shadow Codes Worth Checking

• C0710 5A: Steering Position Signal Plausibility Failure. This indicates the signal from the sensor is not plausible when compared with other vehicle dynamics sensors (like yaw rate or wheel speed). (see via Professional scan tools like the GM Tech 2 or high-end aftermarket scanners (Autel, Launch) can read these suffix codes from the EBCM.)
• C0710 42: Steering Position Signal Calibration Not Programmed. This code sets specifically when the sensor has not been calibrated. (see via Visible on professional scan tools when accessing the EBCM fault codes.)
• C0710 0F / C0710 17: Steering Position Signal Erratic / Shape/Waveform Failure. These codes point to an inconsistent or malformed signal from the sensor, often caused by internal sensor failure or the fretting corrosion issue at the connector. (see via A GM-specific scan tool can pull these detailed fault descriptors.)

Scan Tool Commands That Help

• GM Tech 2 / Autel / Launch: Steering Wheel Angle Sensor Centering / Learn — This procedure is mandatory after replacing the steering angle sensor, the EBCM, or after performing a wheel alignment to teach the EBCM the new straight-ahead position.
• Autel: Steering Wheel Angle Sensor Reset — Some scan tools require performing a 'Reset' function before the 'Learn' procedure. The reset clears the old calibration values from the module, which often triggers the StabiliTrak light, indicating it's ready for the new learn procedure.

Wiring & Ground Locations

• Steering Angle Sensor Connector — On the steering column, under the driver's side dash, typically above the pedals.. This is the primary location for fretting corrosion mentioned in GM TSBs, making it the first place to inspect for a physical fault.
• EBCM (Electronic Brake Control Module) — On the left side frame rail, generally below the driver's door area.. The EBCM receives the signal from the SAS and is the module that sets code C0710. All wiring for the sensor ultimately routes here.
• G300 / G302 — G300 is located on the body mount below the driver's door. G302 is below the right side of the passenger's seat. Some forum posts mention cleaning grounds on the frame under the driver's door is a key step for ABS-related codes.. These are major chassis ground points. A poor ground here can cause a variety of issues with the EBCM and other modules, leading to erratic behavior and fault codes.
• G103 — Located on the cowl in the left rear of the engine compartment, often above the brake booster.. This is a critical ground point for the Body Control Module (BCM) and the Data Link Connector (DLC). While not a direct ground for the EBCM on all platforms, poor communication or erratic behavior can sometimes be traced back to this ground.

Real Owner Repair Stories

• Tahoe Yukon Forum user (2012 GM SUV (platform shared with Silverado)) — Service StabiliTrak and traction control lights with code C0710.
  ❌ Tried (didn't work) Multiple dealership visits could not diagnose the cause.
  ✅ What actually fixed it The user reported that after replacing a rack and pinion, an alignment was performed incorrectly, leaving the steering wheel off by one full turn. Disconnecting the steering shaft under the hood and re-centering it to match the sensor's zero point resolved the code.
• Reddit user r/MechanicAdvice (2011 Chevy Silverado 2500 6.6 Duramax) — Service StabiliTrak message with code C0710-5A (Plausibility Failure). The light would come on after turning the wheel a quarter turn, and later came on randomly after sensor replacement.
  ❌ Tried (didn't work) Replacing the steering wheel position sensor.
  ✅ What actually fixed it The user reported that after replacing the sensor, the code returned. Upon checking live data, they discovered they had no sensor input for steering angle, yaw, brake position, or brake pressure, leading them to suspect a faulty EBCM or a communication issue with the module. The thread ended before a final fix was confirmed, but highlights that sensor replacement is not always the solution.

OEM Part Supersession History

• 20910871 → 19418403 — Standard part update by the manufacturer for design improvement or supplier change.
  Heads up: The parts are generally interchangeable, but it is critical to verify the correct part for your specific vehicle, especially for the 2010 model year, which may have used both designs.

Model Year Variations Within This Range

• 2010: The 2010 model year can be a transition year for the steering angle sensor. Parts catalogs often refer to a '1st Design' and '2nd Design' sensor, identified by the part number labeled on the original sensor (e.g., 'Labeled 20910871'). It is crucial to visually inspect the old part or verify by VIN before ordering a replacement.
