DR5 - Check Continuity to PCM

- Key Off.

- CMP sensor vehicle harness connector disconnected.

- Disconnect PCM. Inspect for damaged or pushed out pins, corrosion, loose wires, etc. Service as necessary.

- Install breakout box, leave PCM disconnected.

- Measure resistance between CID circuit at the CMP vehicle harness connector and Test Pin 85 (CID) at the breakout box and between SIG RTN circuit at the CMP vehicle harness connector and Test Pin 91 (SIG RTN) at the breakout box.

- Are resistance measurements less than 5.0 ohms?

YES -- Go to DR6. DR6 - Check CID For Short to Power

NO -- SERVICE open circuit. REMOVE breakout box. RECONNECT all components. Rerun quick test. Diagnostic Subroutines (DSR) - Extracting Codes
