This bulletin is being revised to add models and conditions. Please discard Corporate Bulletin Number 08-03-16-001 (Section 03 - Suspension).

### Condition

Some customers may comment that the key fobs are inoperative or that the TPM system is showing dashes as the reading for all four tires.

Technicians may find DTCs C0775, C0569 and B3105 set simultaneously in the RCDLR module.

In addition, the technicians may find Tire Pressure Monitoring sensors are unable to be programmed to the vehicle by adding or releasing pressure to the tire while the vehicles in the TPM learn mode.

### Cause

These conditions may be caused by the following:

• | The RCDLR may lose its transmitter and tire pressure monitoring data from its memory if a low voltage condition occurs on the vehicle.

• | The ability for TPM learning by adding or releasing pressure to the tire has been disabled in the RCDLR.

### Correction

Reprogram the RCDLR with an updated software calibration to address both issues listed above. This new service calibration is available on TIS2WEB using Service Programming System (SPS). As always, make sure your Tech 2® is updated with the latest software.

Important: If the Tech 2® could not establish communication with the RCDLR AND the programming event ended with error, contact TCSC for further assistance.

Once the RCDLR module has been reflashed with the latest software and calibrations, the following may also be necessary:

• | Relearn all keyless entry transmitters.

• | Reconfigure the tire pressure placards and the tire type.

• | Relearn the tire pressure sensors.

Refer to SI for the procedures to relearn transmitters, placard and tire type configuration and tire pressure sensor learn.
