Chevrolet Captiva Service & Repair Manual: 2013-15 Captiva Sport
Tire pressure monitor (TPM) system
uses instrument panel cluster (IPC), body control module (BCM), remote control
door lock receiver (RCDLR), keyless entry transmitter, four radio frequency
transmitting pressure sensors, and serial data circuit to perform TPM learn
mode functions. Sensor learn procedure must be performed after every tire
rotation, RCDLR replacement, or sensor replacement. Once learn mode has
been enabled, each of sensors unique identification codes can be learned
into RCDLR memory. When a sensor ID has been learned, RCDLR sends a serial
data message to BCM to sound a horn chirp. This verifies sensor has transmitted
its ID and RCDLR has received and learned it. RCDLR must learn sensor IDs
in proper sequence to determine correct sensor location. First learned ID
is assigned to lefthand front location, second righthand front, third to
righthand rear and fourth to lefthand rear. Turn signals will individually
illuminate indicating which location is to be learned in proper sequence. |
Each sensor has an internal low
frequency coil. When TPM special tool is used in activate mode, it produces
a low frequency transmission that activates sensor. Sensor responds to a
low frequency activation by transmitting in learn mode. When RCDLR receives
a learn mode transmission while in TPM learn mode, it will assign that sensors
ID to location on vehicle relative to order in which it was learned. |
Learn mode will cancel if ignition
is cycled to OFF or if more than two minutes has elapsed for any sensor
that has not been learned. If learn mode is cancelled before first sensor
is learned, original sensor IDs will be maintained. If learn mode is canceled
after first sensor is learned, following will occur: All stored sensor IDs
will be invalidated in RCDLR memory, DIC will display dashes instead of
tire pressures and DTC C0775 will be set. |
These conditions will now require
learn procedure to be repeated for system to function properly. |
In event a particular sensor information
is displayed on special tool upon activation but horn does not chirp, it
may be required to rotate wheel valve stem to a different position due to
sensor signal is being blocked by another component. |
1. |
Ignition ON, initiate TPM Learn Mode
using one of following procedures, as follows: |
|
a. |
Initiate TPM Learn Mode, using a suitably
programmed scan tool. A double horn chirp will sound indicating
learn mode has been enabled. Lefthand front turn signal will also
be illuminated. |
|
b. |
On vehicles equipped with keyless
entry, simultaneously press keyless entry transmitters lock
and unlock buttons until a double horn chirp sounds indicating learn
mode has been enabled. Lefthand front turn signal will also be illuminated. |
|
c. |
On vehicles without keyless entry,
press and release driver information center (DIC) "INFO" button
until "TIRE LEARN" message appears on DIC display. Press and hold
"SET/RESET" button until a double horn chirp sounds indicating learn
mode has been enabled. Lefthand front turn signal will also be illuminated. |
2. |
On all models, starting with
lefthand front tire, activate sensor by holding antenna of TPM special
tool aimed upward against tire sidewall close to wheel rim at valve
stem location. Press and release Activate button. Ensure that transmit
indicator on special tool indicates that sensor activation signal
is being transmitted. Wait for a horn chirp. If horn does not chirp,
repeat sensor activation sequence with tool. Once horn chirp has
sounded, sensor information is learned and turn signal in next location
to be learned will illuminate. |
3. |
After horn chirp has sounded and righthand
front turn signal is illuminated, repeat step two for remaining
three sensors in following order: Righthand front, righthand rear,
then lefthand rear. |
4. |
When lefthand rear sensor has been
learned and a double horn chirp has sounded, learn process is complete
and RCDLR exits learn mode. |

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.
When system has calculated that oil life has been diminished, it will indicate that an oil change is required. A "CHANGE OIL" message will come on. Change ...
