What does this fault code mean?
The transmission control module gets no valid signal from the right rear wheel sensor. The sensor measures the wheel's rotational speed for the brake control module (BCM), which passes the vehicle speed on to the transmission over CAN. The code points to a fault in the brake control module, so fault tracing starts there. The transmission uses a basic value for the signal in the meantime.
Possible causes
- The fault lies in the brake control module (BCM)
- A CAN wire that is intermittently broken or shorted, linking the brake module to the transmission module
- Damaged wheel sensor
What you can do
- 1Read the fault codes in the CEM and the brake control module, and fix them first. Do not clear TCM-C003A00 until the root fault is fixed and its code is cleared
- 2Have a workshop trace the brake control module and the right rear wheel sensor with diagnostic equipment
- 3Drive the car once the fault codes are fixed and see whether the code returns
- 4The brake system is safety-critical. If you suspect a fault, have a workshop check it
Symptoms you may notice1
- No noticeable symptoms for the driver
What the fault can affect1
- The transmission control module (TCM) uses a basic value for the signal
