Diagnostic Test
1. CHECK FOR ACTIVE DTCWith the scan tool, read the active DTC's.
Cycle the ignition switch from off to on, leaving the ignition on for a minimum of 90 seconds.
With the scan tool, read the active DTC's.

Cycle the ignition switch from off to on, leaving the ignition on for a minimum of 90 seconds.
With the scan tool, read the active FCM DTC's.
Does the scan tool display this DTC as active?
Yes
- Go To 3
No
- Replace the original Run/Accessory Delay Relay.
- Perform BODY VERIFICATION TEST – VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE).
3. (P305) ACCESSORY DELAY RELAY CONTROL CIRCUIT OPEN
Turn the ignition off.
Remove the FCM from the Integrated Power Module.
Remove the Run/Accessory Delay Relay from the Junction Block.
Measure the resistance of the (P305) Accessory Delay Relay Control circuit from the FCM-IPM connector to the relay connector.
Is the resistance below 10.0 ohms?
No
- Repair the (P305) Accessory Delay Relay Control circuit for an open.
- Perform BODY VERIFICATION TEST – VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE).
Yes
- Inspect the wiring and connectors for damage or shorted circuits. If OK, replace and program the Front Control Module in accordance with the service information.
- Perform BODY VERIFICATION TEST – VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE).
