Land Rover Defender: Operation

A single Tire Pressure Monitoring System (TPMS) hardware configuration is used. The TPMS status information is relayed to the driver with a message, displayed in the Instrument Cluster (IC) message center and an amber warning indicator.

TIRE PRESSURE MONITORING SYSTEM FAULT MESSAGES Connect the Jaguar Land Rover (JLR) approved diagnostic equipment and read the Diagnostic Trouble Codes (DTCs) from the Tire Pressure Monitoring System (TPMS) sensor.

Circuit voltage above threshold:

• B1182-17 - Battery/charging system fault - Test the battery and charging system.

Tire Pressure Monitor Module internal failure:

• B1182-96 - Tire Pressure Monitor Module (TPM) internal failure - Replace the TPM.

Tire pressure sensor signals not received at the start of a drive cycle:

• C1A56-31 (Left Front Tire Pressure Sensor and Transmitter Assembly - Mute from start of drive cycle).
• C1A58-31 (Right Front Tire Pressure Sensor and Transmitter Assembly - Mute from start of drive cycle).
• C1A60-31 (Left Rear Tire Pressure Sensor and Transmitter Assembly - Mute from start of drive cycle).

  C1A62-31 (Right Rear Tire Pressure Sensor and Transmitter Assembly - Mute from start of drive cycle).

Possible causes:

• A spare wheel with a rubber valve is used in place of a road wheel.
• A rubber valve is mounted to the wheel.
• The tire pressure sensor is in 'Ship' mode and it does not transmit signal.
• The embedded battery within the tire pressure sensor has reached the end of its life cycle (Approximately 6 years).

Tire pressure sensors not recognized during a drive cycle:

• C1A56-93 (Left Front Tire Pressure Sensor and Transmitter assembly no operation (During Tire Pressure Monitoring System (TPMS) drive cycle) ).
• C1A58-93 (Right Front Tire Pressure Sensor and Transmitter assembly no operation (During TPMS drive cycle) ).
• C1A60-93 (Left Rear Tire Pressure Sensor and Transmitter assembly no operation (During TPMS drive cycle) ).
• C1A62-93 (Right Rear Tire Pressure Sensor and Transmitter assembly no operation (During TPMS drive cycle) ).

Possible causes:

• When 1 or more wheels swapped over in less than 15 minutes (winter wheel warehouse replacement).
• Radio Frequency (RF) interference of the Tire Pressure Monitoring System (TPMS) signal from the tire pressure sensors to the receiver.
• The tire pressure sensor damaged.
• The tire pressure sensor battery low (Tire pressure sensor greater than 6 years old).

Incorrect tire pressure sensor installed:

• C1A56-4A (Left Front Tire Pressure Sensor and Transmitter assembly - Incorrect component installed).
• C1A58-4A (Right Front Tire Pressure Sensor and Transmitter assembly - Incorrect component installed).
• C1A60-4A (Left Rear Tire Pressure Sensor and Transmitter assembly - Incorrect component installed).
• C1A62-4A (Right Rear Tire Pressure Sensor and Transmitter assembly - Incorrect component installed).

The vehicle has been installed with tire pressure sensors that are not compatible with the Tire Pressure Monitoring System (TPMS), installed on the vehicle. New TPMS TG1C sensors are required to be installed. This claim is not covered by Jaguar Land Rover (JLR) warranty.

Wheel localization:

• C1D18-00 Wheel localization failed.

Check for wheel speed sensor faults.

Invalid Controller Area Network signal received:

• U0001-81 Invalid Controller Area Network (CAN) signal received.

The signals received are vehicle speed from the Anti-lock Brake System (ABS) control module, Ambient Air Temperature (AAT) and ambient air pressure from the Powertrain Control Module (PCM). Read local snapshot data 0xD020 and the 4 byte code identifies the control module at fault.

Implausible Controller Area Network signal received:

• U0001-86 Implausible CAN systems bus signal received from the following control module:
  • Anti-Lock Brake System (ABS) control module
  • Powertrain Control Module (PCM)
  • Instrument Cluster (IC)
  • Body Control Module/Gateway Module (BCM/GWM).

Read local snapshot data 0xD020 and the 4 byte code identifies the control module at fault.

Controller Area Network communication bus missing message:

• U0001-87 CAN communication missing message.

If 1 or more CAN frames have not been received from the following control module:

• Powertrain Control Module (PCM)
• Anti-Lock Brake System (ABS) control module
• Body Control Module/Gateway Module (BCM/GWM)
• Instrument Cluster (IC).

Check the CAN network, and other modules Diagnostic Trouble Codes (DTCs) to find which module has the fault.

Controller Area Network Bus OFF:

• U0001-88 CAN bus OFF.

Check the CAN bus voltages.

Controller Area Network Alive/sequence counter incorrect/not updated:

• U0046-82 Invalid data received from another control module.

Check the snapshot data to determine the invalid data source control module.

Internal Control Module Software Incompatibility:

• U0300-00 Tire pressure monitoring system control module is not configured correctly.

Using the Jaguar Land Rover (JLR) approved diagnostic equipment, reconfigure the Tire Pressure Monitoring System Control Module (TPMSCM) with the latest level software.

Car configuration problems:

• U2300-54 Central configuration - Missing calibration.
• U2300-55 Central configuration - Not configured.
• U2300-56 Central configuration invalid/incompatible.
• U2300-64 Central configuration - Signal plausibility failure.

Do a software update on the Body Control Module/Gateway Module (BCM/GWM), and check the configuration for the vehicle is correct.

Missing local configuration file:

• U3000-51 Missing Local Configuration File (LCF).

Do a software update on the Tire Pressure Monitoring System Control Module (TPMSCM) selecting the correct Local Configuration File (LCF).

TIRE PRESSURE SENSOR INVESTIGATION

When the Tire Pressure Monitoring System (TPMS) warning indicator illuminates in the Instrument Cluster (IC), indicating a TPMS system fault, or 1 of the tires has a cross over the tire in the cluster image, then ask the customer if the following additional accessories are in the vehicle:

• USB chargers
• Insurance cameras
• Direct Current to Direct Current converter (DC/DC)
• Cool boxes
• Navigation
• Radar detectors.

If yes, ask the customer to remove the items, and check if the TPMS warning indicator does not illuminate in the IC.

If the tire pressure sensor is not detected, then ask the customer where the tire pressure sensor was purchased. If the tire pressure sensor is in ship mode, it needs to be put into park mode with a low frequency TPMS tool. This claim is not covered by Jaguar Land Rover (JLR) warranty, this is not a manufacturing defect.
