Normal Operation

The Passive Anti-Theft System (PATS) transceiver communicates with the PATS  key. The control functions are contained in the Instrument Cluster (IC). The IC  carries out all of the PATS  functions such as receiving the identification code from the PATS  key and controlling the engine and transmission enable. The IC  initiates the key interrogation sequence when the key is turned to the ON or START position.

• DTC U2510 (CAN  - Invalid Data For Vehicle Security) - sets when the IC  and Transmission Control Module (TCM) IDs do not match or have not been sent.

This pinpoint test is intended to diagnose the following: 

• IC  calibration (parameters)
• TCM  calibration (parameters)
• IC 
• TCM
