Chevrolet Captiva Service & Repair Manual: 2013-15 Captiva Sport

Tire Pressure Monitor (TPM) system in the 2014 Chevrolet Captiva integrates several components to function effectively. These include the instrument panel Cluster (IPC), Body Control Module (BCM), Remote Control Door Lock Receiver (RCDLR), keyless entry transmitter, four radio frequency transmitting pressure sensors, and a serial data circuit. The TPM system's primary function is to monitor and alert the driver of any significant changes in tire pressure, enhancing vehicle safety and performance.

The TPM learn mode procedure is essential and must be performed after specific maintenance tasks such as tire rotation, RCDLR replacement, or sensor replacement. During the learn mode, each sensor's unique identification code is learned into the RCDLR memory. This process ensures that the system can accurately determine the correct sensor location on the vehicle. Once a sensor ID has been learned, the RCDLR sends a serial data message to the BCM to sound a horn chirp, verifying that the sensor has transmitted its ID, and the RCDLR has successfully learned it.

The sequence of sensor ID learning is crucial for determining the correct sensor location. The first learned ID is assigned to the left-hand front location, the second to the right-hand front, the third to the right-hand rear, and the fourth to the left-hand rear. The turn signals will individually illuminate to indicate which location is to be learned in the proper sequence. It's important to note that if the learn mode is canceled before the first sensor is learned, the original sensor IDs will be maintained. However, if canceled after the first sensor is learned, all stored sensor IDs in the RCDLR memory will be invalidated, and the system will require the learn procedure to be repeated for proper functionality.
