Conditions for Clearing the DTC

NOTE: During normal diagnostic and/or repair verification technicians may find that the ABS, Traction Control and/or Stability indicators may be ON with NO DTCs displayed by the EBCM. Do not replace the EBCM for this condition.

If the ABS, Traction Control and/or Stability indicators are ON with no DTCs set, perform the following steps:

1. Remove the key from the ignition, open and close the driver's door to turn off retained accessory power (RAP) and wait 60 seconds.

2. Ignition ON, if the ABS, Traction Control and/or Stability indicators are still illuminated, operate the vehicle at speeds greater than 16 km/h (10 MPH) to complete the self test. The EBCM should request all indicators to turn OFF.
