Step
Perform an Euro On-Board Diagnostic (EOBD)
System Check.
1
Was the check performed?
1. Turn the ignition ON, with engine OFF.
2. Install a scan tool to the Data Link Connector
(DLC).
3. Review and record the scan tool Failure Records
data.
2
4. Operate the vehicle within Failure Records
conditions as noted.
5. Using the scan tool, monitor specific Diagnostic
Trouble Code (DTC) info for DTC P1382.
Does the scan tool indicate that DTC P1382 failed?
