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.

ABS pump 30736588 - how do you check it is the right part?
A used, working ABS unit for Volvo: pump with number 30736588 (the label also shows 4N51-2C405-EC) and controller 30736589 A. Matching is done by the numbers on the labels.
Volvo ABS unit 30736588 and controller 30736589 A - ATE
This ABS unit has two labels, each with a different set of markings. The pump motor carries the Volvo numbers 30736588 and 4N51-2C405-EC and the code A426G (also visible on the controller), while the controller housing shows the Volvo number 30736589 A and the ATE number 10.0960-0423.3. The first set identifies the hydraulic block with the pump, the second the electronic module. When matching the part, compare both.
Numbers from the labels on this unit
- 30736588 - Volvo number from the label on the pump motor: 30736588
- 4N512C405EC - second number from the pump label: 4N51-2C405-EC
- 30736589A - Volvo number of the controller (marked “Controller”), as on the label: 30736589 A
- 10096004233 - ATE number from the controller label: 10.0960-0423.3
The controller label also carries the marking “CONTROL UNIT DSTC 2WD”. When comparing with the part removed from your car, check above all the Volvo number of the controller, 30736589 A, and the numbers on the pump motor.
Symptoms that call for a check of the ABS unit
The ABS unit is often suspected when your car shows:
- an ABS warning light, sometimes together with the brake warning light,
- an internal controller fault stored in the fault memory,
- no communication with the controller during diagnostics,
- ABS not working during hard braking.
Before replacing the unit, read the fault memory with a diagnostic tester and also check the wheel speed sensors, fuses, connector and battery voltage - a faulty sensor, for example, can cause similar symptoms. After fitting, the brake system must be bled, and on many cars the module also needs to be configured with a diagnostic tester.
Questions about this ABS unit
| Which car does this ABS unit fit? |
|---|
| It is an original unit from a Volvo car. We do not state the model - matching is done by the numbers on the labels: 30736588 on the pump and 30736589 A on the controller. |
| Which number matters most when matching? |
| No single number is enough - compare the Volvo number of the pump (30736588) and the Volvo number of the controller (30736589 A). The ATE number 10.0960-0423.3 additionally helps to confirm the version of the controller. |
| Does the controller need coding after replacement? |
| It depends on the car and the software version. On many cars, replacing an ABS module requires configuration with a diagnostic tester, so it is worth planning for this before fitting. |
| How can you be sure before buying that it is the right part? |
| Read the numbers from the labels of the part removed from your car and compare them with 30736588 and 30736589 A. If you are in any doubt, send us photos of the labels or your VIN. |
