Check the diagnostic trouble code (DTC) and the freeze data, and note them. Then refer to the indicated DTC's troubleshooting, and do the appropriate troubleshooting procedure.
NOTE:
Freeze data indicates the VSA conditions when the first system malfunction that activated the indicator or warning was detected.
The HDS can read the DTC, the freeze data, the current data, and other system data.
