U2013 – Compass Module is not Responding

U2013 Possible Symptoms

Engine Light ON (or Service Engine Soon Warning Light),Amber ABS (Anti-lock Brakes) Light ON,Wrench Light On,Compass readings blank

U2013 Possible Causes

Faulty / intermittent ignition switch connections,J1850 / SCP / CAN Bus wiring intermittently open/shorted to power or ground,Faulty / intermittent connections at Compass module,Faulty / intermittent connections at ABS Control Module (ABS),Faulty / intermittent connections at the instrument cluster (IPC),Faulty / intermittent connections at Powertrain Control Module (PCM)

U2013 Description

This is a manufacturer specific fault code and can be used for several different faults, depending upon what the manufacturer wants to use it for. Controllers communicate over the Serial Communication Protocol (SCP) bus network, also known as J1850 bus, or Controller Area Network (CAN) Bus. These bus communication systems may or may not be fault tolerant, which means any type of intermittent/loose connection between these controllers could cause communication to stop. When these controllers are unable to communicate with each other at any time while the ignition switch is turned on, code U2013 will set.
