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.

BMW ABS pump 3451685274701: hydraulic module with control unit
ABS pump 3451685274701 for BMW is a used original module that regulates brake pressure when a wheel starts to lock up. It is matched by the numbers on its labels, not by the car model alone. The listing does not state the car model or year, so we do not give them here and match the part by its numbers.
Part number 3451685274701 and related numbers
The numbers as written on the labels and as a single string, the way catalogues list them:
- 3451 6852747 01 (catalogue format: 3451685274701), BMW number of the ABS pump (hydraulic part),
- 6852748, BMW number in short form, without the group prefix.
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.
What can point to an ABS pump failure
- the pump motor switches on at unusual moments or runs louder than usual,
- the ABS activates for no reason during normal braking,
- brake fluid leaks from the hydraulic block, which requires immediate action,
- the ABS switches itself off shortly after the engine is started.
First check the wheel sensors, their wiring and the supply voltage. Only a fault code pointing to the module justifies replacing the pump. After fitting, clear the fault codes and, if necessary, bleed the brake system.
Questions and answers
| What is the difference between numbers 3451685274701 and 6852748? |
|---|
| The module carries several numbers, because it is identified both by the car brand and by the manufacturer of the block and control unit. When matching the part, compare all the numbers. |
| 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. |
| 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. |
