With Scan Tool

The Tech 1 can clear ABS/ASR system DTCs using the Mass Storage or Chassis Cartridge.

1. Install the Tech 1 and cartridge.
2. Select ABS/ASR system features.
3. Select "F2: Show DTCs."
4. Select "Clear DTCs."

After clearing codes, wait 15 seconds before turning the ignition OFF to allow the EBTCM to recognize the TECH 1 request and actually clear the codes. Failure to do so may result in an apparent recurrence of a fault code on the next ignition cycle, when, in actuality, the code was never fully cleared during the ignition cycle when the TECH 1 was used.

The ignition must be turned "OFF" and the Tech 1 disconnected before a road test to check system operation and/or for a DTC resetting. This is necessary because the EBTCM will not set DTCs and the ABS/ASR control functions are disabled when the Tech 1 is installed and monitoring the system. The Tech 1 will log DTCs during some of its diagnostic routines, which are described later.
