U0141 on 2011-2014 Chrysler 200: Lost Communication with BCM Fixes

What's Unique About the 2011-2014 Chrysler 200

On many Chrysler products from this era, including the 200, the BCM's functions are integrated into the Totally Integrated Power Module (TIPM). This module acts as both the main fuse/relay box and a central communication hub. Consequently, a U0141 code on a Chrysler 200 often points towards issues with the TIPM, which can range from internal electronic failures to simple power supply problems. Owners often find the root cause is not the expensive module itself, but a simpler electrical fault like a bad ground, corroded connector, or low battery voltage disrupting the sensitive network. An owner on Opinautos described a scenario where a 'NO BUS' message appeared with a U0141 code, and various electronics failed intermittently, highlighting a typical TIPM-related event.

Symptoms You May Notice

• Check Engine Light is on
• Warning lights for other systems (ABS, traction control) may illuminate
• "NO BUS" message may appear on the instrument cluster.
• Interior lights (dome, map) do not work.
• Power windows and door locks are inoperative.
• Headlights (high or low beams) or turn signals fail to operate.
• Radio or infotainment system shuts off unexpectedly.
• Remote keyless entry and security system may not function.
• Wipers may not work or may turn on by themselves.
• Engine may not start or crank

Most Likely Causes

1. Weak or Failing Battery 🔴 High Probability → Shop Vehicle Battery Modern electronic modules are highly sensitive to voltage. A battery providing less than 12.4 volts can cause modules to shut down or fail to initialize correctly, triggering communication codes. A failing battery can also cause flickering lights and slow cranking.
   How to confirm: Use a multimeter to test the battery voltage with the engine off. A healthy battery should read above 12.4V. Test the charging system with the engine running; voltage should be between 13.2V and 14.5V. A load test is the most definitive way to confirm battery health.
   Typical fix: Recharge or replace the battery. Ensure the new battery is correctly registered with the system if the vehicle has a battery sensor.
   Est. part cost: $150-$300
2. Blown Fuse or Faulty Relay 🟡 Medium Probability The BCM/TIPM relies on several fuses for power. Electrical shorts or component failures can cause these fuses to blow, cutting power to the module and causing it to drop off the network.
   How to confirm: Visually inspect all fuses related to the BCM, TIPM, and interior electronics in the under-hood fuse box (TIPM). Use a multimeter to check for power on both sides of the fuses. Check for power at the BCM's main power input pin at the connector.
   Typical fix: Replace the blown fuse. If it blows again, a short circuit must be diagnosed.
   Est. part cost: $1-$10
3. Corroded or Damaged Wiring/Connectors 🟡 Medium Probability The large connectors that plug into the bottom of the TIPM are susceptible to moisture and corrosion, which can interrupt power, ground, or CAN bus signals. The main wiring harness that runs near the front of the engine is also a potential spot for chafing.
   How to confirm: Disconnect the battery. Unlatch the TIPM and lift it to access the connectors underneath. Visually inspect the wiring harnesses and connectors for green/white corrosion, chafing, or loose pins. Gently wiggle the harness while checking for intermittent faults (with the system powered).
   Typical fix: Clean the corroded terminals using a dedicated contact cleaner and a small brush. Repair or replace any damaged sections of wiring. Apply dielectric grease to the connector before reassembly to prevent future moisture intrusion.
   Est. part cost: $10-$100
4. Poor Ground Connection ⚪ Low Probability Body and chassis grounds can corrode over time, creating high resistance that prevents modules from operating correctly. A high-resistance ground can cause a voltage drop that forces a module offline. Some owners have added a supplementary ground wire to fix starting and electrical issues.
   How to confirm: Locate the main ground points for the BCM/TIPM and ensure they are clean, tight, and free of rust or paint. Use a multimeter to perform a voltage drop test on the ground circuit; it should be less than 100mV. Resistance to chassis ground should be under 5 mΩ (milliohms).
   Typical fix: Remove, clean, and re-secure the ground connection. It's good practice to add a star washer for a better connection. Adding a redundant ground strap from the engine or transmission to the chassis is a common preventative fix.
   Est. part cost: $0-$15
5. Faulty Totally Integrated Power Module (TIPM) ⚪ Low Probability → Shop Fuse Box The TIPM used in this generation of Chrysler vehicles is notorious for internal failures of its circuit board, solid-state drivers, and internal relays, which can cause a loss of communication and a host of other electrical gremlins.
   How to confirm: This is typically a diagnosis of exclusion. If all power, ground, and network wiring tests pass, the TIPM itself is the likely culprit. A professional may use an oscilloscope to verify the CAN signal is present going into the TIPM but that the module is not responding.
   Typical fix: Replace the TIPM with a new or remanufactured unit. Companies like Circuit Board Medics offer a repair service for the original module. Replacement often requires programming to the vehicle's VIN, though many remanufactured units are sold as 'plug-and-play'.
   Est. part cost: $300-$800

Rare But Worth Checking

• PCM Software Glitch: Chrysler has issued TSBs for similar communication codes (like U0140) on these models that are resolved with a PCM software update. It's possible U0141 could also be related to a software issue that a dealer can reflash.
• Hard Reset Needed: Some owners and mechanics report that performing a 'hard reset' by disconnecting both battery terminals and holding them together for 10-15 minutes can sometimes resolve temporary communication glitches by forcing all modules to reboot. This is a simple, no-cost diagnostic step to try early on.

Diagnosis Steps

1. Check for other stored trouble codes. Multiple 'U' codes suggest a network-wide problem.
2. Perform a full battery and charging system test. Ensure voltage is stable and above 12.4V with the engine off.
3. Perform a 'hard reset' by disconnecting both battery terminals and touching the leads together for 10-15 minutes to discharge capacitors and reset all modules.
4. Inspect all fuses in the TIPM (under-hood fuse box) related to the BCM, power outlets, and lighting.
5. Visually inspect the large connectors on the underside of the TIPM for any signs of corrosion, water intrusion, or pushed-out pins. Pay close attention to connector 'B', as wiggling it has been reported to cause stalling.
6. Inspect the main wiring harness that runs across the front of the engine bay for any signs of chafing or damage, particularly the twisted pair of CAN bus wires.
7. If available, use a professional scan tool to view the network status and see which modules are online. Attempt to communicate directly with the BCM.
8. If the BCM/TIPM is offline, test the CAN C bus wiring at a known-good module connector (like the ABS module). With the battery disconnected, resistance between the CAN+ and CAN- wires should be ~60 ohms. Note: Measuring at the DLC may not work as it is on a separate diagnostic bus.
9. With the battery reconnected and key on, check CAN bus voltages at the module connector. CAN-H should toggle ~2.5-3.5V and CAN-L should toggle ~1.5-2.5V when the network is active.

Related Codes That Often Appear With This One

• U0100 — Lost Communication with ECM/PCM. If the main engine computer is also offline, it points to a more widespread network or power issue, not just a faulty BCM.
• U0155 — Lost Communication With Instrument Panel Cluster (IPC). The IPC can act as a gateway module, so its failure can prevent the BCM from communicating with other modules.
• U0073 — Control Module Communication Bus 'A' Off. This indicates the entire CAN bus is down, not just a single module, pointing to a major wiring or gateway module fault.

Technical Service Bulletins (TSBs) & Recalls

• While no specific TSB for U0141 on this exact model was found, TSBs for similar models and codes (like U0140) often point to software updates as a potential fix. For example, TSB #18-013-22 for a newer Chrysler model addresses U0141 with a PCM software update.
• Manufacturer TSB Bulletin #1801322 explicitly lists U0141 as "Lost Communication With Ipm (BCM)" alongside other communication faults like U0140 and U0155, noting its relationship to the Electronic Stability Control system.

Platform-Specific Known Issues

• The TIPM in 2011-2014 Chrysler/Dodge/Jeep vehicles is a well-documented point of failure, leading to numerous electrical problems and communication codes like U0141.
• Corrosion on the connectors underneath the TIPM is a frequent cause of communication loss and should be inspected before condemning the module itself.

Mechanic-Grade Diagnostic Values

• CAN C Bus Resistance — expected: ~60 Ω. Failure: A reading of ~120 Ω indicates an open circuit or one of the two terminating resistors is offline. A reading significantly below 60 Ω suggests a short circuit.
• CAN C Bus Voltage (Key On, Engine Off) — expected: CAN High (CAN+) should toggle between 2.5V and 3.5V. CAN Low (CAN-) should toggle between 2.5V and 1.5V.. Failure: Voltages that are stuck high, low, or near zero indicate a short to power or ground on the bus wiring.
• Module Ground Circuit Resistance — expected: < 5.0 mΩ (milliohms). Failure: A higher resistance reading indicates a poor ground connection, which can cause voltage drops and module communication failure.

Scan Tool Commands That Help

• wiTECH (Chrysler Dealer Tool): View Network Topology — This is the first step in network diagnosis to get a visual map of all modules on the bus and see which ones are communicating (green) and which are not (red).
• wiTECH (Chrysler Dealer Tool): Reprogram BCM/TIPM — Used to flash the module with the latest factory software. This can resolve communication issues caused by software glitches, a known issue on similar Chrysler platforms.
• wiTECH (Chrysler Dealer Tool): Vehicle Configuration — This function is required after installing a new or remanufactured TIPM to program the vehicle's VIN and specific options (like sunroof, premium audio, etc.) into the module.

Wiring & Ground Locations

• TIPM Connectors — On the underside of the Totally Integrated Power Module (TIPM), which is the main fuse box in the engine compartment.. These large multi-pin connectors are a common failure point due to corrosion or loose pins. One owner identified wiggling connector 'B' specifically would cause the vehicle to stall, indicating a poor connection within that plug.
• Chassis to Transmission Ground — A supplementary ground can be added from a bolt on the transmission housing to a clean point on the vehicle's chassis/frame.. The factory grounding has been reported as a weak point. At least one owner fixed a persistent no-start/no-crank issue by adding a heavy gauge (4-gauge) ground wire, which improved the electrical stability for all modules.
• Main Battery Ground — On similar Chrysler platforms, the main battery ground cable attaches to the passenger side inner fender.. Corrosion at this primary ground point can create high resistance for the entire vehicle's electrical system, causing widespread communication faults.

Real Owner Repair Stories

• YouTube user 'My DrZ's Channel' (2013 Chrysler 200) — Intermittent no-start, no-crank condition.
  ❌ Tried (didn't work) The owner noted this was the first step taken based on forum research.
  ✅ What actually fixed it Added a supplementary 4-gauge ground wire from a 16mm bolt on the transmission mount to a clean spot on the chassis. This resolved the starting issue.
• 2CarPros Forum User (2013 Chrysler 200) — Vehicle would randomly stall while driving. Would not restart unless the fuse box (TIPM) was tapped or wires were wiggled.
  ❌ Tried (didn't work) Tapping the TIPM was a temporary fix, not a repair.
  ✅ What actually fixed it The owner diagnosed the fault to a bad connection at connector 'B' on the underside of the TIPM. Wiggling this specific connector could reliably cause the engine to stall, isolating the fault to that connection. The final repair was to fix the bad wire/pin in that connector.
• NHTSA ODI #10906901 — An owner of a similar Chrysler platform reported a cascade of electrical issues where the initial codes pulled included U0141, P2533, and C121C. The owner noted that since the first day of these "daily" issues, the list of stored codes more than doubled.
