B211E

B211E-IGNITION RUN/ACC/PAD CONTROL CIRCUIT LOW





For a complete wiring diagram, refer to the Wiring Information.

- When Monitored:
With the ignition on.

- Set Condition:
The Front Control Module will set this DTC within 500ms if the (P305) Accessory Delay Relay Control circuit is open or shorted to ground.





1. CHECK FOR ACTIVE DTC
1. With the scan tool, read the active DTCs.
2. Cycle the ignition switch from off to on, leaving the ignition on for a minimum of 90 seconds.
3. With the scan tool, read the active DTCs.

Does the scan tool display this DTC as active?

Yes

- Go To 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 Body Verification Test.

2. RUN/ACCESSORY DELAY RELAY
1. Turn the ignition off.
2. Install a substitute relay in place of the original Run/Accessory Delay Relay.
3. Cycle the ignition switch from off to on, leaving the ignition on for a minimum of 90 seconds.
4. With the scan tool, read the active FCM DTCs.

Does the scan tool display this DTC as active?

Yes

- Go To 3

No

- Replace the original Run/Accessory Delay Relay.
- Perform the BODY VERIFICATION TEST Body Verification Test.

3. (P305) ACCESSORY DELAY RELAY CONTROL CIRCUIT OPEN




1. Turn the ignition off.
2. Remove the FCM from the Integrated Power Module.
3. Remove the Run/Accessory Delay Relay from the Junction Block.
4. Measure the resistance of the (P305) Accessory Delay Relay Control circuit from the Front Control Module IPM connector to the Relay connector.

Is the resistance below 10.0 ohms?

Yes

- Go To 4

No

- Repair the (P305) Accessory Delay Relay Control circuit for an open.
- Perform the BODY VERIFICATION TEST Body Verification Test.

4. (P305) ACCESSORY DELAY RELAY CONTROL CIRCUIT SHORTED TO GROUND




1. Measure the resistance between ground and the (P305) Accessory Delay Relay Control circuit at the relay cavity (85).

Is the resistance below 100.0 ohms?

Yes

- Repair the (P305) Accessory Delay Relay Control circuit for a short to ground.
- Perform the BODY VERIFICATION TEST Body Verification Test.

No

- Inspect the wiring and connectors for damage or shorted circuits. If ok, replace and program the Front Control Module.
- Perform the BODY VERIFICATION TEST Body Verification Test.
