Enhanced Diagnostics - Variable Effort Steering (VES)

Enhanced diagnostic information is found in the DTC HISTORY function of the scan tool. Enhanced diagnostic information provides the service technician with specific malfunction occurrence information. The following actions occur for each of the last three diagnostic trouble codes that are stored:
- Data is stored to identify the specific DTC.
- The following data is stored:
- The vehicle speed at the DTC set
- The states of the Traction Control System (TCS) and the brake light switches
- Whether the Antilock Brake System (ABS) and TCS were active or passive

- The number of drive cycles since the malfunction last occurred is stored. A drive cycle occurs when the ignition is turned to RUN.
- The drive cycle counter will increment by turning the ignition to the RUN and OFF if a malfunction is not present.
- The last three diagnostic trouble codes are stored in the order of occurrence.
- The Electronic Brake and Traction Control Module (EBTCM) stores only the data that is associated with the most recent occurrence of each code. Data that was previously stored is overwritten by the latest information.
