U0155 GMC code

Error code U0155 indicates that there’s a loss of communication with your Instrument Panel Cluster Control Module (IPC). This occurs when the Powertrain Control Module (PCM) notices that it can no longer communicate with the IPC properly.

What causes U0155 code?

Diagnostic trouble code (DTC) U0155 stands for “Lost Communication with Instrument Panel Control (IPC) Module.” This code is logged when one or more modules (computers) on the vehicle have lost communication with the Instrument Panel Control (IPC) module.

What is an IPC module?

Since Electron applications are broken into two separate processes (main and render), we need a system to communicate between them. That system is in the IPC module. This module allows you to send and receive synchronous and asynchronous messages between the processes.

What does lost communication with TCM mean?

It means that the transmission control module is not communicating with one or more modules that are connected with it through the CAN bus/controller area network system.

How do I fix U0155?

To repair a U0155 code, run a diagnostic test on your vehicle and do any of the following:

  1. Replace or recharge your vehicle’s battery.
  2. Fix any additional error codes which may appear on your scanner.

How do I reset my instrument cluster?

Push and release the Sel/reset button button 3 times repeatedly. The instrument cluster begins its self-test. Each successive press of the Sel/reset button initiates a new cycling of all the gauges. To end, turn the ignition switch to OFF, or vehicle speed exceeds 1.5 mph.

Will disconnecting battery reset TCM?

Will disconnecting battery reset TCM? Disconnecting the battery would not return the TCM to its default settings, and you would need to use a transmission scan method to do so. Simply disconnecting the battery terminals will not complete the phase or solve the gear shift issue.

What causes TCM to fail?

A transmission control module is an electronic device and a burnt circuit is the reason for its failure in most cases. It can be a faulty resistor or transistor on a printed circuit board. Any qualified technician or an experienced car mechanic can fix the problem.

Where is the TCM fuse located?

It should be just below the engine control module’s position. Sometimes it’s found under the center console in the interior or even under the hood near the battery or inner fender panel.

Can communication failure with TCM?

Description: The powertrain control module (PCM) continuously monitors the controller area network (CAN) for messages from the TCM. This DTC sets when the PCM does not receive the TCM message within the defined amount of time. Possible Causes: Damaged CAN communication bus circuit.

How much does it cost to fix U0100 code?

The cost to diagnose the U0100 FORD code is 1.0 hour of labor. The auto repair’s diagnosis time and labor rates vary by location, vehicle’s make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour.
