3. Operate the vehicle within the conditions for running the DTC to verify the DTC does not reset. You may also operate the vehicle within the

conditions that are captured in the Freeze Frame/Failure Records Data List.

Circuit/System Testing

1. Ignition OFF, disconnect the fuel injector multi-way harness connector X145.

Note: Testing for steps 2 through 4 is performed on the ECM side of the multi-way harness connector.

2. Ignition ON, connect a test lamp between each ignition circuit terminal 1/2 and ground. The test lamp should illuminate at each ignition

circuit.

瀚慖f the test lamp does not illuminate, test the ignition circuits for a short to ground, or an open/high resistance. If the circuits test normal

and the ignition circuit fuse is open, test or replace the appropriate Q17 fuel injector.
