Diagnostic Test

  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 step  2

      No 

  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 step  3

      No 

  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 

      No 

      • Go to step  4
