X1 - Check VPWR Circuit Continuity
- Key Off.
- IAC disconnected.
- Disconnect CCRM.
- Disconnect Scan Tool from DLC.
- Measure resistance between the VPWR circuit at the IAC solenoid vehicle harness connector and Pins 12 and 24 (VPWR) of the CCRM vehicle harness connector.
- Are both resistances less than 5.0 ohms?
YES -- RECONNECT IAC solenoid. GO to X2. X2 - Check B(+) and IGN Start/Run Voltage to CCRM
NO -- SERVICE open VPWR circuit between the CCRM and the splice to the IAC solenoid. RECONNECT all components. Rerun quick test. Diagnostic Subroutines (DSR) - Extracting Codes
