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.

How do you check that ABS unit 51896323 is the one you are looking for?
A used, working, original ATE ABS unit: pump with number 51896323 and ATE 10.0212-0593.4, and a control unit with ATE number 10.0961-2806.3. Matching is done by part numbers.
ABS pump and control unit 51896323 - ATE, Alfa Romeo Giulietta, Fiat, Lancia
The pump motor of this unit carries a label with the number 51896323, the ATE number 10.0212-0593.4 and the marking “GERMANY”. The control unit housing has a second label with the ATE number 10.0961-2806.3 and the markings “Controller” and “CONTROL UNIT ESP”. Both labels show the ATE logo and the Lancia, Fiat and Alfa Romeo marks. Catalogues link these numbers to the Alfa Romeo Giulietta. The unit is used, working and original.
Part numbers to match against
- 51896323 - part number (OEM) from the label on the pump motor: 51896323
- 10021205934 - ATE number from the pump label: 10.0212-0593.4
- 10096128063 - ATE number from the control unit label: 10.0961-2806.3
The control unit label also shows other ATE markings and the text “MADE IN HUNGARY”. To compare with your own part, the three numbers listed above are enough - start with 51896323, then check both ATE numbers.
When an ABS unit needs checking
The most common signs are:
- an ABS or stability control warning light that does not go out,
- a control unit fault stored in the fault memory,
- no communication with the module during diagnostics,
- ABS and ESP switched off under hard braking.
Before you decide to replace it, read the fault codes with a diagnostic tester and rule out simpler causes: wheel speed sensors, connectors, fuses and battery voltage. After fitting, the brake system must be bled, and on many cars the module also needs to be configured with a diagnostic tester.
Questions before you order

| Start with 51896323, then check the ATE numbers 10.0212-0593.4 (pump) and 10.0961-2806.3 (control unit). All three should match. |
| Does the control unit need coding after replacement? |
| It depends on the car and the software version. On many cars a replacement module needs to be configured with a tester, so it is worth planning for this before fitting. |
