PINPOINT TEST B: DTC U2511 - DATA MISMATCH (RECEIVE DATA DOES NOT MATCH EXPECTED)

B1-B2:

Normal Operation
The passive anti-theft system (PATS) transceiver communicates with the PATS key. The instrument cluster carries out all of the PATS functions such as receiving the identification code from the PATS key and determining whether the key is a programmed key. The instrument cluster initiates the key interrogation sequence when the key is turned to the START or RUN position.

Possible Causes
- parameter reset not carried out
- powertrain control module (PCM) calibration
- instrument cluster
