JA22 - Check CKP Circuit Resistance - ICM Disconnected

- Key Off.

- Disconnect ICM from ICM tee, leave EI diagnostic harness connected to vehicle harness connector.

- DVOM on 20K ohm scale.

- Measure resistance between J48 (CKP- I) and J35 (CKP+ I) at breakout box.

- Is resistance between 2580 and 2700 ohms?

YES -- REPLACE ICM. REMOVE all test equipment. RECONNECT all components. Clear continuous memory. Clearing Diagnostic Trouble Codes

Rerun quick test. Diagnostic Subroutines (DSR) - Extracting Codes

NO -- Resistance fault. Go to JA14. JA14 - Check For Resistance High or Resistance Low Fault
