C2007 on 2017-2018 Land Rover Discovery: EPB Actuator Fault Causes and Fixes

What's Unique About the 2017-2018 Land Rover DISCOVERY

For the 2017-2018 Discovery (L462 generation), Land Rover has explicitly acknowledged via TSB LTB01248NAS1 that this code can be triggered by a software error in the ABS control module. This makes a software-based fix a high-probability first step. A simple driver-initiated recalibration procedure or a dealer software update can often resolve the issue without replacing any parts. This is a crucial first step before assuming the more common hardware failure of the EPB actuator motor, which is integrated into the rear brake caliper on this platform, unlike the separate, cable-driven module on the older Discovery 3/4.

Diagnostic Flowchart

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

Symptoms You May Notice

• "Park Brake needs Calibration" message on the instrument cluster.
• EPB (Electric Park Brake) warning lamp is illuminated (amber or red).
• Parking brake will not release, potentially stranding the vehicle.
• Parking brake fails to engage, or does not hold the vehicle on an incline.
• A loud screeching or grinding noise from the rear of the vehicle when operating the EPB.
• "Park Brake Fault" message displayed on the instrument cluster.

Most Likely Causes

1. ABS Control Module Software Error 🔴 High Probability Land Rover issued Technical Service Bulletin LTB01248NAS1 specifically identifying a software error as the cause for DTCs C2007-72 and C2008-72 on this vehicle, often appearing with a 'Park Brake needs Calibration' message. Low battery voltage or battery disconnection can also trigger this software-related fault.
   How to confirm: Attempt the EPB recalibration procedure. If the fault clears, it was a software glitch. If it returns, a dealer can check if a software update is available using the JLR Pathfinder diagnostic system, as specified in the TSB.
   Typical fix: First, attempt a 'no-tool' recalibration. If that fails, a dealer needs to update the ABS Control Module software using their diagnostic equipment. The recalibration often involves a sequence of locking the car, waiting, and then operating the EPB switch with the engine running and foot on the brake.
   Est. part cost: $0
2. Failed Right EPB Actuator/Motor 🟡 Medium Probability The actuator is an electromechanical component mounted directly on the rear brake caliper. This location exposes it to significant heat, water, road salt, and debris, which can lead to internal corrosion, electronic failure, or mechanical seizure of the motor.
   How to confirm: If a software update/recalibration doesn't fix it, a technician will use a scan tool to command the motor. If it doesn't respond despite receiving power and ground at the connector, the motor is faulty. This is the definitive test after software issues are ruled out.
   Typical fix: The EPB motor is integrated with the rear brake caliper, and the entire assembly is replaced. The system must be put into 'Service Mode' using a scan tool before replacement to retract the piston. After installation, the brake system must be bled and the EPB system calibrated.
   Est. part cost: $120-$360
3. Wiring or Connector Damage ⚪ Low Probability The wiring harness leading to the rear caliper is exposed to road debris and constant suspension movement. This can cause wires to chafe, break, or corrode within the loom, and the connector pins can suffer from water ingress and corrosion.
   How to confirm: A visual inspection of the harness and connector at the right rear wheel is the first step. A multimeter is used to perform a pin-to-pin continuity and voltage drop test from the ABS module to the actuator connector to find opens or high resistance.
   Typical fix: Repair the damaged section of the wiring harness or replace the connector pigtail. In some cases, corrosion can travel up the wire, requiring a new section to be soldered in.
   Est. part cost: $20-$100

Diagnosis Steps

1. Connect a Land Rover-compatible scan tool (e.g., JLR Pathfinder, Autel, GAP IIDTool) to read codes from the ABS Control Module and confirm C2007-72 is present.
2. Check for eligibility for TSB LTB01248NAS1, which addresses an ABS software update for this exact issue.
3. Perform the Park Brake recalibration procedure as described in TSB SSM74004: Lock the vehicle and wait ten minutes. Unlock, start the engine, and with your foot on the brake, press the EPB switch down to release (wait 2s), then pull up to apply. Wait for the red 'P' light to become solid.
4. If the code returns, have a dealer or qualified shop with JLR Pathfinder software (version 196 or later) check for and apply any available ABS control module software updates.
5. If the software is up to date and the code persists, raise and safely support the vehicle.
6. Visually inspect the wiring harness and connector at the right rear brake caliper for corrosion, damage, or loose pins. Pay close attention to where the harness flexes with suspension travel.
7. If wiring is intact, use the scan tool to place the EPB system into 'Service/Mounting Mode'. This retracts the brake piston.
8. Remove the caliper and inspect the brake pads and slide pins for seizure or excessive wear.
9. If mechanical parts are okay, use a multimeter to test for power and ground at the motor connector while an assistant operates the EPB switch (or use the scan tool's active command).
10. If power and ground are present but the motor does not work, the right rear caliper with integrated EPB motor needs to be replaced.
11. After replacement, the brake system must be bled and the EPB system must be calibrated using the diagnostic tool.

Parts You'll Likely Need

• Rear Right Brake Caliper with EPB Motor (OEM #LR102242) — If a software fix is not the solution, the internal motor of the EPB actuator has likely failed. On this vehicle, it is serviced as a complete caliper assembly. This part number is for the standard brake setup; vehicles with performance brakes may use a different part number (e.g., a red caliper).
  Trusted brands: Land Rover (Genuine), TRW (Often the OEM supplier)
  OEM price range: $250-$360
  Aftermarket price range: $120-$220

Related Codes That Often Appear With This One

• C2008-72 — This is the corresponding code for the left motor ('Actuator Stuck open'). TSB LTB01248NAS1 explicitly states that both C2007-72 and C2008-72 are often triggered together by the same ABS software glitch.
• C2005-71 — This code for 'Right actuator – Actuator Stuck' can also be logged during the same fault event, indicating the actuator is stuck in the applied position, which can happen if the motor fails intermittently.
• C2006-71 — This code for 'Left actuator – Actuator Stuck' can also be logged during the same fault event.
• U2002-13 — This code, meaning 'Switch general electric failure – circuit open', can sometimes accompany EPB faults, pointing to a wiring issue supplying the main EPB switch or module.

Technical Service Bulletins (TSBs) & Recalls

• LTB01248NAS1: States that C2007-72 may be caused by an ABS Control Module software error, causing an EPB warning lamp and a 'Park Brake needs Calibration' message.
• SSM73905: Defines C2007-72 as 'Right Motor – Actuator Stuck open' within the ABS module.
• SSM74004: Provided the user-level recalibration procedure for a software-induced fault message.

Platform-Specific Known Issues

• Land Rover Technical Service Bulletin LTB01248NAS1 directly addresses this code on 2017+ Discovery models, stating the cause may be an ABS Control Module software error that requires an update with Pathfinder.
• TSB SSM73905 also lists C2007-72 as 'Right Motor – Actuator Stuck open', confirming the component at fault when a hardware issue is present.
• TSB SSM74004 describes a specific software corruption scenario where interrupting a release command with an apply command (e.g., opening a door while shifting into Drive) can trigger the 'Park Brake needs Calibration' message and associated DTCs, including C2007-72.

Mechanic-Grade Diagnostic Values

• LIN Bus Voltage at EPB Actuator Connector — expected: Toggling voltage between approximately 1V and 1V less than battery system voltage (e.g., ~11-12V) when the EPB switch is operated.. Failure: A steady 0V may indicate an open or short to ground. A steady battery voltage (e.g. 12V) without toggling could indicate a short to power or a non-responsive module.

Hidden / Shadow Codes Worth Checking

• C2007-72: Right Motor – Actuator Stuck open. This is the most common variant, indicating the ABS module commanded the motor to apply the brake, but it failed to move from the released position. (see via A Land Rover-compatible scan tool (Pathfinder, GAP IIDTool, Autel, iCarsoft) capable of reading manufacturer-specific codes from the Anti-lock Brake System (ABS) module.)
• C2007-01: Right Motor - General electrical failure. This variant points to a problem in the electrical circuit itself, such as a short to ground, short to power, or an open circuit in the wiring to the actuator motor. (see via A Land Rover-compatible scan tool capable of reading manufacturer-specific sub-codes from the Anti-lock Brake System (ABS) module.)

Scan Tool Commands That Help

• JLR Pathfinder, Autel, GAP IIDTool, iCarsoft, Snap-On Ethos: EPB Service Mode / Maintenance Mode / Pad Replacement / Move to Mounting Position — This command MUST be used before any physical work on the rear brakes. It fully retracts the electric motor's piston, allowing the brake caliper piston to be compressed safely without causing damage to the internal mechanism.
• JLR Pathfinder, Autel, GAP IIDTool, iCarsoft, Snap-On Ethos: Exit Maintenance Mode / Move to Latching Position — This command MUST be used after the rear brake components have been reassembled. It commands the motor to move out and find the new biting point on the pads, recalibrating its position.
• JLR Pathfinder: Update ECU (for ABS Control Module) — This is the dealer-level fix specified in TSB LTB01248NAS1 to resolve the software error that can cause C2007-72. It requires Pathfinder version 196 or later.

Real Owner Repair Stories

• YouTube user 'T1T L' (2017 Land Rover Range Rover Sport (platform-mate with identical EPB system)) — Parking brake fault warning on the dashboard, DTC C2007 'Right motor general electrical failure'.
  ❌ Tried (didn't work) The video focuses on the diagnosis of the found fault.
  ✅ What actually fixed it The fault was traced to a previous, improper wiring repair on the harness leading to the right rear caliper motor. The wires had been poorly connected. The final fix was to correctly repair the damaged wiring harness.

OEM Part Supersession History

• LR102242 → LR102242 (current) — This is the part number for the standard Right Rear Caliper with EPB motor.
  Heads up: Vehicles equipped with optional performance brakes use a red-painted caliper, which has a different part number: LR102244 (Right Rear). The standard caliper is not a direct replacement if the vehicle has red calipers.
• LR102245 → LR102245 (current) — This is the part number for the standard Left Rear Caliper with EPB motor, which is often replaced at the same time or can log the corresponding C2008 code.
  Heads up: Vehicles equipped with optional performance brakes use a red-painted caliper, which has a different part number: LR102247 (Left Rear).

Model Year Variations Within This Range

• 2017-2018: TSB LTB01248NAS1, which identifies a software error as a primary cause for C2007-72, is specifically applicable to the 2017 model year and newer. This makes checking for an ABS software update via the JLR Pathfinder tool a critical first diagnostic step for this specific vehicle range, as opposed to earlier models on different platforms.
