IMPORTANT:
- When using this diagnostic, more than one vehicle key is required to ensure proper diagnosis. If more than one key is not available at the time of service, contact the customer and ask if any other keys can be provided for service. If unavailable, a new second key can be created.
- Interference from an RF device located on the keychain may cause this DTC to set. Remove any RF devices from the keychain before proceeding with the diagnostic.
- Inspect all available vehicle keys that they are correct vehicle keys.
- If not a correct vehicle key, replace the key.
- While viewing the scan tool TDM Transponder Key parameter, turn ON the ignition with each of the available vehicle keys. The parameter should read Present with all available keys.
- If only one key results in the parameter reading Not Present, replace the appropriate key.
- If all available keys result in the parameter reading Not Present, replace the TDM.
