A faulty transmission control module (TCM) most often causes limp mode with the gearbox stuck in one gear, harsh jolts when you select D or R, erratic gear changes, flashing PRND letters and a gearbox or engine warning light. However, the same symptoms are often caused by a low gearbox oil level, a weak battery, a poor earth or a faulty sensor. To test a transmission control module, start by checking the battery and reading the fault codes with a diagnostic tool that can talk to the gearbox control unit, then check the power supply, the connector, the oil and the live data. Below we explain the symptoms, the diagnostic steps and what the most common fault codes mean.

Chrysler Voyager: how do you match the ABS unit P04721452AA?
A used, working ABS unit with pump and control unit for a Chrysler Voyager. Numbers: P04721452AA and ATE 25.0206-1130.4, 25.0926-4329.3 and 25.0610-1281.4.
ABS pump with control unit - Chrysler Voyager, P04721452AA
The ABS control unit works in a loop: it reads the speed of each wheel, calculates the slip and, if it exceeds the permitted limit, opens or closes the relevant valves. Meanwhile the return pump draws off fluid and maintains pressure, which is why the brake pedal pulsates noticeably. This listing describes a unit marked as a Chrysler Voyager, with one OEM number and three ATE numbers. That is a lot of markings, but they are exactly what allows the version to be identified unambiguously.
The full set of unit markings
- P04721452AA - OEM part number: P04721452AA
- 25020611304 - ATE number: 25.0206-1130.4
- 25092643293 - ATE number: 25.0926-4329.3
- 25061012814 - ATE number: 25.0610-1281.4
Three ATE numbers mean that one unit contains components marked separately by the system manufacturer. We do not decide which number refers to which component - check that all three match.
How an ABS module failure shows itself
The most common signs include:
- an ABS warning light that is permanently on,
- faults pointing to the valves or the module electronics,
- the ABS function switching off when braking,
- no communication with the control unit during diagnosis.
Start diagnostics by reading the fault codes and checking the wheel sensors and fuses. After the unit is replaced, the brake system must be bled; depending on the car, coding or adaptation may also be needed.
