P0513-INVALID SKIM KEY
For a complete wiring diagram, refer to the Wiring Information.
-
When Monitored:
With the ignition on.
-
Set Condition:
The Powertrain Control Module (PCM) receives and invalid SKIM Key message from the Wireless Control Module (WCM).
Possible Causes |
|---|
| INCORRECT VIN PROGRAMMED IN THE PCM |
| UNPROGRAMMED IGNITION KEYS |
| WIRELESS CONTROL MODULE (WCM) |
| POWERTRAIN CONTROL MODULE (PCM) |
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 28 - DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure).
1. CHECK FOR SKREEM/WCM COMMUNICATION AND DTCs
| NOTE: | An external Radio-Frequency Identification (RFID) key (and/or pass/radio key), such as one used to gain access to a 24 hour gym, can cause this DTC to set and create a no start condition. Inspect the customer's key chain for any type of RFID key. If one is not found, question the customer to see if a spare key chain has this RFID key on it or if it was removed from the original key chain before the vehicle was released for service. If a RFID key is present, remove the ignition key from the vehicle and remove the RFID key from the key chain. After performing the appropriate reset procedure, attempt to start the vehicle. If the vehicle does not start, continue with the diagnostic test. |
| 1. | Ignition on, engine not running. |
| 2. | With the scan tool, check for proper communication and active DTCs in the WCM. |
Are any WCM communication problems or DTCs present?
Yes
- (Refer to 28 - DTC-Based Diagnostics/MODULE, Wireless Control (WCM) - Diagnosis and Testing) and perform the appropriate diagnostic procedure.
No
- Go To 2
| 1. | Turn the ignition on. |
| 2. | With the scan tool, erase all PCM DTCs. |
| 3. | Turn the ignition on and off several times pausing 10 seconds between key cycles. |
| 4. | With the scan tool, select View DTCs in the PCM. |
Is the status Active for this DTC?
Yes
- Go To 3
No
- Perform the INTERMITTENT DTC diagnostic procedure. (Refer to 28 - DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure).
3. REPROGRAM IGNITION KEYS AND RETEST
| 1. | Turn the ignition on. |
| 2. | With the scan tool, clear all ignition keys out of WCM memory. |
| 3. | With the scan tool, reprogram all ignition keys to the WCM. |
| 4. | Turn the ignition on and off several times pausing 10 seconds between key cycles. |
| 5. | With the scan tool, select View DTCs in the PCM. |
Is the status Active for this DTC?
Yes
- Go To 4
No
| 1. | Replace and program the WCM in accordance with the service information. |
| 2. | Turn the ignition on. |
| 3. | With the scan tool, clear all PCM DTCs. |
| 4. | Turn the ignition on and off several times pausing 10 seconds between key cycles. |
| 5. | With the scan tool, select View DTCs in the PCM. |
Is the status Active for this DTC?
Yes
- Replace and program the Powertrain Control Module in accordance the service information.
- Perform the PCM VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure).
No
