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 PCM equipped vehicles, the vehicle should start once the RFID key is removed. 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. CHECK COMMUNICATION WITH WIN
1. With the scan tool, attempt to communicate with the WIN.

Can the scan tool communicate with the WIN?

Yes

- Go To 3

No

3. CHECK FOR WIN TROUBLE CODES SET
1. With the scan tool, check for WIN DTCs.

Are any DTCs present in the WIN?

Yes

- Go to and perform the appropriate diagnostic procedure. Testing and Inspection
- Perform the WIN VERIFICATION TEST. Wireless Ignition Node (WIN) Verification Test.

No

- Go To 4

4. CHECK FOR THE 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. Programming and Relearning.
- Perform the WIN VERIFICATION TEST. Wireless Ignition Node (WIN) Verification Test.

5. POWERTRAIN CONTROL MODULE
1. Turn the ignition off.
2. Replace and program the WIN.
3. Ignition on, engine not running.
4. With the scan tool, erase all WIN 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

- Check the PCM harness connector terminals for corrosion, damage, or terminal push out. Repair as necessary. Replace and program the Powertrain Control Module. Programming and Relearning.
- Perform the WIN VERIFICATION TEST. Wireless Ignition Node (WIN) Verification Test.

No

- Test Complete.

6. IGNITION KEY

NOTE: You must obtain the WIN pin number.

NOTE: This DTC could have been set if the WIN harness connector was disconnected, or if the WIN 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 WIN.
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 DTC P0513 still active?

Yes

- Replace the Ignition Key. Programming and Relearning.
- Perform the WIN VERIFICATION TEST. Wireless Ignition Node (WIN) Verification Test.
