U129E: Unraveling The Mystery Of Your Car’s Communication Failure
The U129E code is a Diagnostic Trouble Code (DTC) related to the Controller Area Network (CAN) system in automobiles.
It indicates that the Powertrain Control Module (PCM) has lost communication with the Keyless AccessTPMS Control Unit. This happens when the PCM does not receive signals from the Keyless AccessTPMS Control Unit via the F-CAN lines for a set time. The U129E code is stored in the PCM as a result of this malfunction.
FAQ
If you see the engine light on or the service engine soon warning light, it could be due to the u129e fault code. This code is often caused by a faulty keyless access/TPMS control unit, an open or shorted harness, a poor electrical connection in the control unit circuit, or a faulty powertrain control module. To fix this issue, you should visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector pins.
If you’re experiencing an Engine Light ON (or Service Engine Soon Warning Light) due to a faulty Keyless Access/TPMS Control Unit, you can visually inspect the related wiring harness and connectors to fix the issue. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. Make sure to also check for an open or shorted harness and poor electrical connection in the Keyless Access/TPMS Control Unit circuit. If the issue persists, check the Powertrain Control Module (PCM) for faults.
Yes, it is necessary to check for damaged components and connector pins when fixing the U129E fault code. This is because a faulty Keyless Access/TPMS Control Unit, open or shorted harness, poor electrical connection, or a faulty Powertrain Control Module (PCM) can cause the engine light to turn on. To fix the issue, it is important to visually inspect the related wiring harness and connectors, and check for any damaged components or broken, bent, pushed out, or corroded connector pins.
Wrap Up
If you see the Engine Light ON or Service Engine Soon Warning Light, it could be due to a faulty Keyless AccessTPMS Control Unit, open or shorted harness, poor electrical connection, or a faulty Powertrain Control Module (PCM).
Check the possible causes, inspect the wiring harness and connectors, and look for damaged components or corroded pins.
