Details of the Jaguar u1262 OBD Code

Jaguar U1262 code indicates a communication fault between the vehicle modules.

Jaguar OBD code U1262 means that there is a communication issue between the vehicle’s SCP (Standard Corporate Protocol) data bus and the instrument cluster module.

This code is triggered by the instrument cluster module when it detects a lack of communication or invalid data coming from the SCP data bus.

The SCP data bus is a network that allows various modules in the vehicle to communicate with each other.

In this case, the instrument cluster module is not receiving the expected data or signals from the SCP data bus, leading to the U1262 fault code being set.

When diagnosing a U1262 code in a Jaguar, it is important to check the wiring and connections between the instrument cluster module and the SCP data bus.

Issues such as loose connections, damaged wiring, or faulty modules can cause communication problems and trigger this fault code.

Mechanic’s Tech Notes

This section provides detailed information on diagnosing and repairing Jaguar fault code U1262.

To diagnose and fix OBDII code U1262 in a Jaguar, start by checking the Transmission Control Module (TCM) power and ground using a multimeter.

Verify TCM communication over the Controller Area Network (CAN) network with a scan tool.

If the TCM does not respond, reprogramming or reflashing may be necessary.

Visually inspect the wiring harness and connectors for any damage, and check connector pins for signs of being broken, bent, pushed out, or corroded.

This thorough inspection can help identify and resolve the communication issue causing the U1262 fault code.
