The BCM monitors the state of the RAP output by checking the voltage level on the accessory voltage input.
The BCM will be ready to test for and set this DTC when:
The BCM detects one of the following incorrect voltage conditions on the BCM program input:
The DTC will clear when the fault is corrected and the DTC memory clearing procedure is completed. Refer to On-Board Diagnostic Features in Body Control System.
If the only DTC that flashes is a history code, DTC 33, the problem is intermittent. Refer to Testing for Electrical Intermittents in Wiring Systems.

Does the test lamp remain OFF? | Go to Step 8 | Go to Step 7 |
5 | Test the RAP B+ circuit for an open or a short to ground. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 12 | Go to Step 10 |
6 | Test the circuits between the accessory voltage input circuit and the RAP output circuit for a short to voltage. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 12 | Go to Step 10 |
7 | Test the circuits between the accessory voltage input circuit and the RAP output circuit for a short to ground. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 12 | Go to Step 10 |
8 | Test the accessory voltage input circuit for an open. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 12 | Go to Step 9 |
9 | Test the BCM RAP output for an open. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 12 | Go to Step 10 |
10 | Inspect for poor connections at the harness connectors for the BCM. Refer to Testing for Intermittent and Poor Connections and Connector Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 12 | Go to Step 11 |
