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 to identify ABS pump 3451677538801 for your BMW
This module is made by ATE. ABS pump 3451677538801 is sold together with its control unit, just as it is fitted to BMW cars. The listing does not state the car model or year, so we do not give them here and match the part by its numbers.
Numbers to compare
The numbers from the listing, as written on the labels and as a single string:
- 3451 6775388 01 (catalogue format: 3451677538801), BMW number of the ABS pump (hydraulic part),
- 3452 6775389 01 (catalogue format: 3452677538901), BMW control unit number,
- 10.0613-3307.3 (catalogue format: 10061333073), additional number from the listing.
Matching by number is more reliable than matching by car model. Compare all the numbers and ask us if any of them does not match.
Symptoms of a faulty ABS pump or control unit
- valve or pump motor faults are stored in the control unit memory,
- the ABS activates for no reason during normal braking,
- the ABS warning light comes on together with the stability control warning light,
- on a slippery surface the wheels lock up noticeably sooner than they used to.
Before buying a module, read the fault codes with a diagnostic tester. A faulty wheel speed sensor or its wiring can cause the same symptoms, and in that case replacing the pump will not help. After replacement the fault codes usually need to be cleared, and if the brake lines have been disconnected, the system must be bled.
Questions and answers
| Are the make and model of the car enough to choose the part? |
|---|
| No. A single model comes with different versions of the module, depending on the engine, year of manufacture and drivetrain. The most reliable reference is the number on the original pump. |
| 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. |
| Is this a new part? |
| No. We sell used original modules, each one inspected before sale. You will find the warranty period in the product features table. |
