1. Erase the DTC memory.
2. Read the DTC.

Is DTC 76-3x indicated?

YES - Go to step 3.

NO - Intermittent failure, system is OK at this time. Go to Troubleshooting Intermittent Failures. Initial Inspection and Diagnostic Overview If another DTC is indicated, go to the DTC Troubleshooting Index. Diagnostic Trouble Code Descriptions
