B211A-IGNITION RUN/ACC/SPAD CONTROL CIRCUIT LOW





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

- When Monitored:
Continuously.

- Set Condition:
When the Cluster senses a low condition on the (F103) Ignition Run/ACC Relay Control circuit for over 10 seconds, this code will set.





1. TEST FOR INTERMITTENT CONDITION
1. With the scan tool, record and erase DTCs.
2. Cycle the ignition from on to off.
3. Turn the ignition on.
4. With the scan tool, read DTCs.

Does the scan tool display: B211A-IGNITION RUN/ACC CONTROL CIRCUIT LOW?

Yes

- Go To 2

No

- The conditions that caused this code to set are not present at this time. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

2. IGNITION RUN/ACC DELAY RELAY
1. Turn the ignition off.
2. Install a substitute relay in place of the original Ignition Run/ACC Delay Relay.
3. Cycle the ignition switch from off to on, leaving the ignition on for a minimum of 30 seconds.
4. With the scan tool, read the DTCs.

Does the scan tool display this DTC as active?

Yes

- Go To 3

No

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

3. JUNCTION BLOCK

NOTE: Perform this test with the relay removed.

1. Turn the ignition off.
2. Disconnect the Junction Block C2 connector (on top of junction block).
3. From the Relay cavity 85, measure the resistance to ground.

Is the resistance below 10K Ohms?

Yes

- Replace the Junction Block.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Go To 4

4. (F103) IGNITION RUN/ACC RELAY CONTROL CIRCUIT SHORTED TO GROUND




1. Disconnect the Cluster C2 harness connector.
2. Measure the resistance between ground and the (F103) Ignition Run/ACC Relay Control circuit in the Cluster C2 connector.

Is the resistance below 10K ohms?

Yes

- Repair the (F103) Ignition Run/ACC Relay Control circuit for a short to ground.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Replace the Cluster.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
