Transmission Control Module (TCM) fault code (Freelander 2)

Gearbox control unit

NOTE: If a module or component failure is suspected and the vehicle remains under manufacturer's warranty, refer to the Warranty Guide (Section B1.2) or determine if there is a previously approved special program in effect before replacing the component.

NOTE: Generic scan tools may not be able to read the codes listed or may only be able to read 5-digit codes. Match the 5 digits from the scan tool with the first 5 digits of the listed 7-digit code to identify the fault (the last 2 digits provide additional information readable by the manufacturer-approved diagnostic system).

NOTE: When performing voltage or resistance tests, always use a digital multimeter (DMM) with three decimal places of accuracy and a valid calibration certificate. When testing resistance, be sure to include the resistance of the DMM leads.

NOTE: Before starting diagnostic programs using fault location tests, check and correct basic faults.

NOTE: Inspect the connectors for signs of water ingress and their pins for damage and/or corrosion.

NOTE: If DTCs are set and the fault is not present after performing the troubleshooting tests, an intermittent problem may be the cause. Be sure to check for loose connections and corroded terminals.

U0401-00	Invalid data received from the engine control module (ECM)	Incorrect signal from ECM	Perform a full read of vehicle diagnostic trouble codes indicating a Controller Area Network (CAN) bus or ECM failure. Correct as necessary. Refer to the Warranty Policy and Procedures manual if an ECM failure is suspected.
U0415-00	Incorrect data received from the anti-lock brake system (ABS) control unit	The Engine Control Module (ECM) contains an incorrect code for the immobilizer. The ABS module (Brake Control Module (BCM)) contains an incorrect code for the immobilizer. Transmission control module (TCM) malfunction.	Reprogram units as necessary. Refer to the Warranty Policy and Procedures manual if unit failure is suspected.
U2100-00	Primary configuration is not configured	Malfunction of the electrical circuit of the CAN data bus. The initial configuration data for the central unit was not transmitted.	Check for other diagnostic trouble codes related to Controller Area Network (CAN) faults or which are not believed to be related to the customer complaints. Perform a full vehicle DTC reading. Check the CAN bus circuits. Refer to the electrical diagrams. Correct if necessary. Clear the DTCs and check for proper operation. Check if the correct version of the vehicle configuration software is installed in the central unit. Reprogram the unit if necessary.
U2101-00	Control unit configuration incompatibility	The central unit configuration parameter is missing or corrupted	Check if the correct version of the vehicle configuration software is installed in the central unit. Reprogram the unit if necessary.
U2023-00	Engine torque signal	Local Area Network (CAN) bus circuit (between engine control module (ECM) and transmission control module (TCM)): open circuit. CAN circuit (between ECM and TCM): short circuit. CAN unit malfunction.	Read all relevant DTCs completely. Correct as necessary. Check CAN bus circuits. Refer to electrical diagrams. Correct as necessary.
U2105-11	Signal "A" of the switch block	Shift Lock Solenoid Circuit Malfunction: Short to Ground. Gearbox selector module (GSM) malfunction.	Check GSM and electrical circuits. Refer to electrical diagrams. Correct if necessary. If GSM failure is suspected, refer to the warranty policy and procedures manual.
U2105-12	Signal "A" of the switch block	Shift Lock Solenoid Circuit Malfunction: Short to Power. Gearbox selector module (GSM) malfunction.	Check GSM and electrical circuits. Refer to electrical diagrams. Correct if necessary. If GSM failure is suspected, refer to the warranty policy and procedures manual.
U3003-62	Battery voltage	Voltage mismatch between battery and transmission control module (TCM): difference more than 2 V	Check TCM power supply circuit. Refer to electrical diagrams. Correct as necessary.
