- 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.
- 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
