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.

Numbers to compare
The numbers from the listing, as written on the labels and as a single string:
- 12801328, original Saab number,

- 13509104G, additional number from the listing,
- 54084714A, additional number from the listing.
The full numbers matter, including their endings. If in doubt, send us a photo of your pump.
What can point to an ABS pump failure
- the brake pedal pulses or feels uneven for no obvious reason,
- valve or pump motor faults are stored in the control unit memory,
- the pump motor switches on at unusual moments or runs louder than usual,
- the ABS activates for no reason during normal braking.
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
| What is the difference between numbers 12801328 and 13664004? |
|---|
| 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. |
| 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. |
| 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. |
| What condition is this ABS module in? |
| It is an original recycled part in good condition, checked by us. Warranty details are in the product features table. |
