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.

When an ABS module needs replacing
- the ABS stops working, although basic braking usually remains functional,
- the brake pedal pulses or feels uneven for no obvious reason,
- valve or pump motor faults are stored in the control unit memory,
- on a slippery surface the wheels lock up noticeably sooner than they used to.
It is worth reading the fault codes and checking the sensor wiring before replacement. Fitting and bleeding the brake system are usually carried out by a garage with the right equipment.
Questions and answers
| Does a lit ABS warning light always mean a faulty pump? |
|---|
| No. Read the fault codes first, because the cause may be a wheel sensor, its wiring or too low a supply voltage. |
| Do the brakes need bleeding after replacing the module? |
| If the brake lines are disconnected during fitting, the system must be bled. The fault codes in the control unit usually need to be cleared as well. |
| Who makes this module? |
| The module is made by ATE. The manufacturer's name does not change the numbers you should use to match the part. |
| What condition is this pump in? |
| It is a used original part, inspected before sale. You will find the warranty period in the product features table. |
