Tech 1 Diagnostic Computer Method
- To clear ABS/ASR DTCs, use Mass Storage or Chassis Cartridge. Install Tech 1 and cartridge, and select ABS/ASR system feature. Set Tech 1 to "F2: Show DTCs". Select "Clear DTCs".
- Turn ignition off and disconnect Tech 1. Road test vehicle, checking system operation and/or DTC resetting. This must be done because EBTCM will not set DTCs and ABS/ASR control functions are disabled when Tech 1 is installed and monitoring system.
