Circuit/System Verification

Ignition ON, observe the DTC information with a scan tool. Verify that DTCs P1610 or P1611 are not also set.
- If DTCs P1610 or P1611 are set, refer to DTC P1610 or P1611 for further diagnosis.
Engine idling, observe the ignition voltage parameter with a scan tool. The ignition voltage should be between 12-15 volts.
If the vehicle passes the Circuit/System Verification Test, then operate the vehicle within the conditions for running the DTC. You may also operate the vehicle within the conditions that are captured in the Freeze Frame/Failure Records Data List.
