B2205-ORIGINAL VIN MISSING/MISMATCH
For a complete wiring diagram, refer to the Wiring Information.
-
When Monitored:
At ignition on, after ignition on during any rolling code handshake that occurs with the Powertrain Control Module (PCM) due to a Sentry Key remote Entry Module (SKREEM) also known as the Wireless Control Module (WCM) or PCM reset.
-
Set Condition:
A valid key is recognized but the programmed VIN does not match between the WCM and PCM/ECM.

1. DETERMINING IF DIAGNOSTIC TROUBLE CODE (DTC) IS CURRENT
| 1. | With the scan tool, erase the WCM DTCs. |
| 2. | Turn the ignition off. |
| 3. | Wait 10 seconds. |
| 4. | Turn the ignition on and wait 2 minutes. |
| 5. | With the scan tool, read the WCM DTCs. |
Does the scan tool display the DTC that was previously erased?
Yes
- Go To 2
No
- Go To 4
| 1. | Turn the ignition on. |
| 2. | With the scan tool, select Engine system from the main menu. |
| 3. | Display and record the Vehicle Identification Number. |
| NOTE: | Ensure that a VIN has been programmed into the PCM. If a VIN is not displayed, attempt to program the PCM with the correct VIN before continuing. |
Does the VIN recorded from the PCM match the VIN of the vehicle?
Yes
- Go To 3
No
- Replace and program the Wireless Control Module in accordance with the Service Information.
- Perform the WCM VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Wireless Control (WCM) - Standard Procedure)
3. REPLACE WCM AND CHECK DTC'S
| 1. | Turn the ignition off. |
| 2. | Replace and program the Sentry Key Remote Entry Module in accordance with the Service Information. |
| 3. | Turn the ignition on. |
| 4. | With the scan tool, display and clear all PCM and WCM DTCs. |
| 5. | Perform 5 ignition key cycles leaving the ignition key on for 90 seconds per cycle. |
| 6. | With the scan tool, check for WCM DTCs. |
Does the scan tool display the same DTC?
Yes
- Replace and program the Powertrain Control Module in accordance with the Service Information.
- Perform the WCM VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Wireless Control (WCM) - Standard Procedure)
No
- The repair is complete.
- Perform the WCM VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Wireless Control (WCM) - Standard Procedure)
| 1. | Turn the ignition off. |
| NOTE: | Check for the following conditions: |
Were any problems found?
Yes
- Repair wiring harness/connectors as necessary.
- Perform the WCM VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Wireless Control (WCM) - Standard Procedure)
No
