Detailed Description of Error U0136

Error U0136, also known as ''Lost Communication With Differential Control Module Rear'', is an OBDII trouble code that indicates a loss of communication between the vehicle''s onboard computer (OBDII) and the rear differential control module. This module is responsible for controlling the vehicle''s rear differential, which helps to distribute power to the wheels during various driving conditions. When the OBDII system detects a lack of communication with this module, it triggers the U0136 code and illuminates the ''Check Engine'' light on the dashboard. This code can be triggered by a variety of issues, including faulty wiring, module failure, or other electrical problems within the vehicle.

Possible Causes of Error U0136

There are several potential causes for the U0136 error code, including:

  • Wiring issues: Faulty or damaged wiring between the OBDII system and the rear differential control module can cause a loss of communication.
  • Module failure: A malfunctioning rear differential control module can prevent communication with the OBDII system.
  • Electrical problems: Issues with the vehicle''s electrical system, such as a short circuit or blown fuse, can disrupt communication between the OBDII and the rear differential control module.
  • Software glitches: In some cases, a software issue within the OBDII system or the rear differential control module can cause the U0136 error code.

Possible Fixes for Error U0136

To address the U0136 error code, it''s essential to diagnose the underlying issue. Here are some possible fixes:

  • Check wiring: Inspect the wiring between the OBDII system and the rear differential control module for any signs of damage or corrosion. Repair or replace the wiring as necessary.
  • Replace the module: If the rear differential control module is faulty, it may need to be replaced. This should be done by a qualified automotive technician.
  • Address electrical issues: Identify and repair any electrical problems within the vehicle, such as short circuits or blown fuses.
  • Update software: If a software glitch is suspected, update the software in the OBDII system or the rear differential control module to the latest version.
