Diagnostic Test
1. CHECK FOR SKIM COMMUNICATION AND DTCSTurn the ignition on.
With the scan tool, check for Sentry Key Immobilizer Module communication and DTCs.
Are any SKIS problems or DTCs present?
Yes
- Refer to symptom list for problems related to SKIM Communication and DTCs before continuing.
- Perform the ECM Verification Test Ver. 1 (Refer to 9 - ENGINE - DIAGNOSIS AND TESTING).
No
- Go To2
2. CHECK FOR ECM DTCS
NOTE: If the ECM detects and stores a DTC, the ECM also stores the engine/vehicle operating conditions under which the DTC was set. Some of these conditions are displayed on the scan tool at the same time the DTC is displayed.
NOTE: Before erasing stored DTCs, record these conditions. Attempting to duplicate these conditions may assist when checking for an active DTC.
With the scan tool, erase ECM DTCs.
Turn the ignition on and off several times pausing 10 seconds between each key cycle.
With the scan tool, read the ECM DTCs.
Did this DTC set again?
Yes
