[SOLVED] Fixing U1267 Code: Esm Can Communication Error

The automobile fault code U1267 indicates a problem with the Electronic Shift Module (ESM) in your vehicle. The most common symptom of this issue is the Engine Light turning on or the Service Engine Soon Warning Light.

The cause of this fault code could be a faulty ESM, an open or shorted ESM harness, or a poor electrical connection in the ESM circuit. It is important to address this issue promptly as it can affect the performance of your vehicle. The repair process involves visually inspecting the wiring harness and connectors, checking for damaged components, and looking for broken, bent, pushed out, or corroded connector’s pins.

The repair time for this issue is estimated to be around 1.0 hour.

It is crucial to interpret the fault code correctly to ensure the proper repair is made.

The cost of repair is influenced by the repair time, which is commonly charged between $75 and $150 per hour by most auto repair shops.

Therefore, the total cost of fixing the U1267 fault code will depend on the hourly rate charged by the repair shop and the estimated repair time required to fix the issue.

The U1267 code is a Transmission Control Module (TCM) fault code.

It occurs when there is a problem with both CAN busses. The TCM cannot receive data from the Electronic Shift Module (ESM) to determine the shifter position. This code sets when there is no valid data from ESM on CAN C or CAN DPT.

In other words, the TCM is unable to communicate with the ESM due to a problem with the CAN circuits.

What are the possible causes of the u1267 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the u1267 fault code. This code is usually caused by a faulty Electronic Shift Module (ESM), an open or shorted ESM harness, or poor electrical connection in the ESM circuit. To fix this issue, you should visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

How can one visually inspect the related wiring harness and connectors to fix the u1267 fault code?

If you’re experiencing the u1267 fault code, which is indicated by the Engine Light ON or Service Engine Soon Warning Light, there are a few things you can do to fix it. The cause of this issue could be a faulty Electronic Shift Module (ESM), an open or shorted ESM harness, or a poor electrical connection in the ESM circuit. To address these issues, you should visually inspect the related wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector’s pins.

What are the consequences of ignoring the u1267 fault code and not fixing it in a timely manner?
