P0513-INVALID SKIM KEY







- When Monitored:
Ignition on.

- Set Condition:
The Powertrain Control Module (PCM) detects an invalid SKREEM key. One Trip Fault.





Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. Pre-Diagnostic Troubleshooting Procedure.

1. ACTIVE DTC

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. For GPEC equipped vehicles, disconnect the battery and wait a minimum of 5 minutes, reconnect and attempt to start the vehicle. For NGC equipped vehicles, turn the ignition on a minimum for one hour, and then 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, read the PCM DTCs.

Is the DTC active at this time?

Yes

- Go To 2

No

- Go To 6

2. NO COMMUNICATION WITH SKREEM
1. With the scan tool, attempt to communicate with the SKREEM.

Can the scan tool communicate with the SKREEM?

Yes

- Go To 3

No

- No Response From WCM (Wireless Control Module) (Sentry Key Remote Entry Module) Perform the No Response from WCM (Wireless Control Module) diagnostic procedure.

3. SKREEM TROUBLE CODES SET
1. With the scan tool, check for SKREEM DTCs in the WCM

Are any DTCs present in the SKREEM?

Yes

- Testing and Inspection Perform the appropriate diagnostic procedure.

No

- Go To 4

4. VIN PROGRAMMED INTO PCM
1. With the scan tool, display the VIN that is programmed in the PCM.

Has a VIN been programmed into the PCM?

Yes

- Go To 5

No

- Program the correct VIN into the PCM and retest.
- Perform the POWERTRAIN VERIFICATION TEST. Powertrain Verification Test.

5. PCM
1. Turn the ignition off.
2. Replace and program the SKREEM.
3. Ignition on, engine not running.
4. With the scan tool, erase all SKREEM and PCM DTCs.
5. Attempt to start and idle the engine.
6. With the scan tool, read the PCM DTCs.

Does the scan tool display this code?

Yes

- NOTE: Before continuing, check the PCM harness connector terminals for corrosion, damage, or terminal push out. Repair as necessary.
- Replace and program the Powertrain Control Module.
- Perform the POWERTRAIN VERIFICATION TEST. Powertrain Verification Test.

No

- Test Complete.

6. IGNITION KEY

NOTE: You must obtain the SKREEM pin number.

NOTE: This DTC could have been set if the SKREEM harness connector was disconnected, or if the SKREEM was replaced recently.

NOTE: All keys that the customer uses for this vehicle must be tested to verify they are operating properly.

1. Ignition on, engine not running.
2. Verify the correct VIN is programmed into the PCM and SKREEM.
3. Turn the ignition off.
4. With each customer key, turn the ignition on and crank the engine to start.
5. With the scan tool, read the PCM DTCs. Look for P0513.

NOTE: If this DTC cannot be reset, it could have been an actual theft attempt.

Is the Good Trip Counter for DTC P0513 displayed and equal to 0?

Yes

- Replace the Ignition Key.
- Perform the WIRELESS CONTROL MODULE VERIFICATION TEST. Wireless Control Module (WCM) Verification Test.

No

- Test Complete.
