Test G: DTC U2511 - CAN - Data Mis-Match (Receive Data Does Not Match Expected)

PINPOINT TEST G: DTC U2511 - CAN - DATA MIS-MATCH (RECEIVE DATA DOES NOT MATCH EXPECTED)

G1:

G2-G5:

Normal Operation
The passive anti-theft system (PATS) uses a visual anti-theft indicator located in the instrument cluster. This indicator proves out for 3 seconds when the key is turned to the ON or START position under normal operation. If there is a PATS concern, this indicator either flashes rapidly or glows steadily (for more than 3 seconds) when the key is turned to the ON or the START position. PATS also flashes the anti-theft indicator every 2 seconds at key off to act as a visual theft deterrent. The anti-theft indicator operation is controlled by the instrument cluster.

DTC U0100 (Lost Communication With ECM/PCM) - sets when the instrument cluster loses communication with the PCM.

DTC U2510 (CAN - Invalid Data for Vehicle Security) - sets when the instrument cluster receives an invalid PCM ID over the HS-CAN network. The instrument cluster ID and the PCM ID do not match and this DTC is set. This DTC can be set if either the instrument cluster or the PCM is replaced without resetting the parameters in both modules, or if there is an issue with either the instrument cluster or the PCM. This DTC can also be set if the battery is low.

DTC U2511 (CAN - Data Mis-Match (Receive Data Does Not Match Expected) - sets when the instrument cluster does not receive the expected response from the PCM over the HS-CAN network. The data sent by the PCM does not match the data expected by the instrument cluster and this DTC is set. This DTC can be caused by the HS-CAN circuits between the instrument cluster and the PCM or by either module. This DTC can also be set if the battery is low.

This pinpoint test is intended to diagnose the following:
- Low battery SOC
- Mis-matched parameters
- Instrument cluster
- PCM
