With Antilock Brake System - Bosch 5.3

The DTCs in the EBTCM memory are erased in one of two ways:
- Are erased by the scan tool method.
- Are erased by ignition cycle default. This requires 100 ignition cycles to pass with no detection of the DTCs.

Always verify the proper system operation and always verify absence of DTCs when the clearing procedure is completed.
The following methods will not clear DTCs:
- DTCs cannot be cleared by unplugging the EBTCM.
- DTCs cannot be cleared by disconnecting the battery cables.
- DTCs cannot be cleared by turning the ignition switch to the OFF position. However, DTCs can be cleared on the 100th cycle of the ignition cycle default.

SCAN TOOL METHOD
Use the Clear DTC(s) function of the scan tool to clear the ABS/TCS system DTCs.
The ignition switch must be turned to the OFF position and the scan tool disconnected before performing a road test to check system operation and/or for a DTC reset. This is necessary because the EBTCM will not set DTCs and ABS/TCS control functions are disabled when the scan tool is installed and monitoring the system.

IGNITION CYCLE DEFAULT
If the ignition switch is cycled 100 times without a particular DTC reappearing, that DTC will be erased from EBTCM memory and the ignition cycle counter for that fault in the EBTCM will be reset to zero.
