4. (F20) IGNITION SWITCH OUTPUT (RUN-START) CIRCUIT OPEN OR SHORTED Turn the ignition on. Using a 12-volt test light connected to ground, check the (F20) Ignition Switch Output (Run-Start) circuit. Does the test light illuminate brightly? Yes Go To 5 . No Repair the (F20) Ignition Switch Output (Run-Start) circuit for an open or short. Perform the WCM VERIFICATION TEST. Refer to «STANDARD PROCEDURE»(ref-485546-S13917643862012071300000) .
5. (D55) AND (D54) CAN B BUS CIRCUITS OPEN NOTE: One open circuit will not cause this condition. Measure the voltage between the (D54) CAN B Bus (-) circuit and ground. Measure the voltage between the (D55) CAN B Bus (+) circuit and ground. Is there any voltage present on either circuit? Yes Replace the Wireless Control Module in accordance with the Service Information. Perform the WCM VERIFICATION TEST. Refer to «STANDARD PROCEDURE»(ref-485546-S13917643862012071300000) . No Repair the (D55) and (D54) CAN B Bus circuits for an open. Inspect the connector for damage. Perform the WCM VERIFICATION TEST. Refer to «STANDARD PROCEDURE»(ref-485546-S13917643862012071300000) .
