CMTC Internal Failure
NOTE:
After making any repairs, perform BODY VERIFICATION TEST
under VERIFICATION TESTS.
Monitored & Set Condition
- When Monitored: When a SELF TEST command is received from the scan tool, the CMTC performs a series of tests on the microprocessor, compass coil and internal circuitry.
- Set Condition: The code will be set, if during the self test the CMTC detects a problem with the microprocessor, compass coil or the internal circuitry.
Possible Causes:
- CMTC/EVIC Internal Failure
Testing
- When the trouble code FAILED SELF TEST is displayed, replace the CMTC or EVIC. See OVERHEAD CONSOLES - CONCORDE, INTREPID & 300M article. If the vehicle is equipped with a Tire Pressure Monitor (TPM), the EVIC must be retrained.
