Circuit/System Verification
- Ignition ON, observe the scan tool ECM PNP Switch parameter while shifting the transmission through each range. The reading should change between Park/Neutral and In Gear.
- If not the specified value, refer to PNP Switch Malfunction.
- Command the Starter Relay ON with the scan tool, or turn the ignition switch to the START position. The starter solenoid should click and the engine should crank.
- If the solenoid does not click, refer to STRTR Relay Malfunction.
- If the solenoid clicks but the engine does not crank, refer to Starter Solenoid Clicks, Engine Does Not Crank .
