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.

It receives signals from the speed sensors on all wheels and uses them to decide when to operate the valves and the motor of pump 4B0614517G. When a sensor sends incorrect data, the control module normally switches off the ABS function and a warning light appears on the dashboard. The markings on the unit include the text ‘ESP’.

Most common signs of unit failure
A faulty ABS unit usually makes itself known through:
- a lit ABS warning light,
- an internal control module fault in the fault memory,
- no communication with the module during diagnostics,
- the brake warning light coming on.
Before replacement, read the fault memory with a diagnostic tool and check that the culprit is not a wheel speed sensor, fuse, wire or connector; it is also worth measuring the battery voltage. After fitting, bleed the brake system and, if the car requires it, code the control module and carry out a basic setting of the ESP sensors.
