6.IGNITION KEY
NOTE: You must obtain the SKIM pin number.
NOTE: This DTC could have been set if the SKIM harness connector was disconnected, or if the SKIM was
replaced recently.
NOTE: All keys that the customer uses for this vehicle must be tested to verify they are operating properly.
Ignition on, engine not running.
Verify the correct VIN is programmed into the ECM and SKIM.
Turn the ignition off.
With each customer key turn the ignition on and crank the engine to start.
With the scan tool, read the ECM DTCs. Look for P0513.
Is the DTC P0513 still active?
Ye s>>
Replace the Ignition Key.
Perform SKIM VERIFICATION. (Refer to 8 - ELECTRICAL/VEHICLE THEFT SECURITY - STANDARD
PROCEDURE)
No>>
Te s t C o m p l e t e .
NOTE: If this DTC cannot be reset, it could have been an actual theft attempt.

When Monitored:
While the engine is running.
Set Condition:
The ECM does not read a change in value from the sensor over time.
Possible Causes
BATTERY TEMP SENSOR
INTERMITTENT CONDITION
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 9 - ENGINE -
DIAGNOSIS AND TESTING)
Diagnostic Test
1.BATTERY TEMP SENSOR
Remove the temperature sensor and reconnect the wiring harness connectorto the sensor.
Monitor scan tool, while heating the sensor with an external heat source (DO NOT USE OPEN FLAME).
Does the reading from the sensor increase at least 5 degrees F. on the scan tool?
Ye s>>
Refer to the INTERMITTENT CONDITION Symptom (Diagnostic Procedure). (Refer to 9 - ENGINE -
DIAGNOSIS AND TESTING)
No>>
Replace the battery temperature sensor.
