The DTCs in the EBCM/EBTCM memory are erased in one of two ways:

    • Scan tool method.
    • Ignition cycle default. This requires 100 ignition cycles to pass with no detection of the DTC.

       Important: After DTC C0036, C0041, C0046, C0051, C0056, and C0110 are cleared by ignition cycle default the vehicle must be driven above 12 Km/h (8 mph) for the ABS/TCS indicator(s) to turn off.

Whichever method is used, be sure to verify proper system operation and absence of DTCs when the clearing procedure is completed.

DTCs cannot be cleared by unplugging the EBCM/EBTCM, disconnecting the battery cables, or by turning the ignition OFF (except on the 100th cycle of ignition cycle default without the malfunction reappearing).
