DTC C2111: Tire Pressure Sensor 1 in Shipping Mode

DTC C2112: Tire Pressure Sensor 2 in Shipping Mode

DTC C2113: Tire Pressure Sensor 3 in Shipping Mode

DTC C2114: Tire Pressure Sensor 4 in Shipping Mode

Circuit/System Description

The tire pressure monitor (TPM) system has a radio frequency (RF) transmitting pressure sensor in each wheel/tire assembly. The module receives and translates the data contained in the tire pressure sensor RF transmissions into sensor presence, sensor mode, and tire pressure.

The receiver module receives a radio frequency (RF) transmission from each tire pressure sensor. Each sensor RF transmission contains its own unique identification (ID) code that must be learned into the module memory. Once all 4 IDs have been learned, the module continuously compares IDs received in transmission to its learned IDs to determine if all 4 sensors are present.

Conditions for Running the DTC

The ignition is ON.

Conditions for Setting the DTC

The tire pressure sensors stop transmitting signals.

Action Taken When the DTC Sets

The Tire Pressure Warning Light is illuminated.

Conditions for Clearing the DTC

A current DTC will clear when the signal transmission is resumed.

Diagnostic Aids

If the displayed tire pressure data did not change within 3 minutes, refer to DTC C2121-C2124 .

Circuit/System Verification

With the scan tool, record tire pressure sensors ID and locations:

1. Rapidly reduce the tire pressure for each wheel at least 6 psi within 30 seconds. It may take up to 3 minutes for the display to change.
2. Check that each tire pressure data displayed has changed.

Repair Instructions

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
