Diagnostic Test
- CHECK FOR ACTIVE DIAGNOSTIC TROUBLE CODE (DTC)
- Turn the ignition on.
- Using the scan tool, read the active DTCs.
Does the scan tool display this DTC as active?
Yes
- Go to step 2
No
- If the DTC is stored, check for an intermittent condition. Visually inspect the related wiring harness connectors. Look for broken, bent, pushed out or corroded terminals.
- Perform the BODY VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Front Control (FCM) - Standard Procedure .
- REMOTE START RELAY
- Turn the ignition off.
- Install a substitute relay in place of the original Remote Start Relay.
- Cycle the ignition switch from off to on, leaving the ignition on for a minimum of 90 seconds.
- Using the scan tool, read the active FCM DTCs.
Does the scan tool display this DTC as active?
Yes
- Go to step 3
No
- Replace the original Remote Start Relay.
- Perform the BODY VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Front Control (FCM) - Standard Procedure .
- (K617) REMOTE START RELAY CONTROL CIRCUIT SHORTED TO VOLTAGE
- Turn the ignition off.
- Disconnect the IPM C1 harness connector.
- Remove the Remote Start Relay.
- Turn the ignition on.
- Measure the voltage of the (K617) Remote Start Relay Control circuit at the relay connector (cavity 85).
Is the voltage above 10.0 Volts?
Yes
- Repair the (K617) Remote Start Relay Control circuit for a short to voltage.
- Perform the BODY VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Front Control (FCM) - Standard Procedure .
No
- Go to step 4
- INTEGRATED POWER MODULE (IPM) / FRONT CONTROL MODULE (FCM)
- Turn the ignition off.
- Reconnect the IPM C1 harness connector.
- Remove the FCM from the IPM.
- Turn the ignition on.
- Measure the voltage of the (K617) Remote Start Relay Control circuit at the relay connector (cavity 85).
Is the voltage above 10.0 Volts?
Yes
- Replace the IPM in accordance with the Service Information.
- Perform the BODY VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Front Control (FCM) - Standard Procedure .
No
- Replace the FCM in accordance with the Service Information.
- Perform the BODY VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Front Control (FCM) - Standard Procedure .
