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.

When the ABS module does not respond: unit P04726568AI for Jeep
Used, working, genuine ABS pump and control module unit. Two part numbers (OEM) and one ATE number. Selection is by part numbers.
Jeep - ABS P04726568AI, 00534550950, ATE 28.5159-0707.3
The diagnostic tool connects to the engine and gearbox, but the ABS module stays silent. This is a common reason why people start looking for a unit. Before you do, rule out the power supply and earth. If the problem persists, move on to the numbers. This unit for Jeep is used, working and genuine. We do not state the model.
Numbers on the labels
- P04726568AI - part number (OEM): P04726568AI
- 00534550950 - part number (OEM): 00534550950
- 28515907073 - ATE number: 28.5159-0707.3
The number 00534550950 begins with two zeros. They are easy to lose when copying it out. The ATE number may be written as 28515907073. The first number has the letter P at the start and AI at the end. We do not specify the roles of the individual numbers.
When there is no connection with the ABS
Typical observations with this kind of fault:
- the diagnostic tool cannot find the ABS module in the list,
- the ABS and brake warning lights are on at the same time,
- other control modules store a lost-communication-with-ABS fault,
- the warning lights go out briefly after a restart.
Check the fuses supplying the module and its earth. Inspect the connector for corrosion and moisture. Measure the voltage with the engine running. If everything is within normal limits and there is still no communication, compare the numbers with the listing. After fitting, bleed the system and ask about configuration.
