Code 8 (Control Unit)
CONTROL UNITExplanation
This defect code is stored when the program of the Electronic Throttle Control (EML) control unit detects a defect in one of the memory modules of the EML control unit.
NOTE: The defect code can also be stored as the result of a temporary defect in the EML warning lamp.
Troubleshooting
- Check EML voltage supply and battery charge (status monitoring).
- Proceed with other displayed scan tool diagnostic instructions where applicable.
- If no defect can be found but the customer complains of faults in the EML system and the defect code counter reading is >10, renew the EML control unit.
