Checking diagnostic trouble codes (DTCs) in the central electronic module
Checking diagnostic trouble codes (DTCs) in the central electronic module
Checking other diagnostic trouble codes (DTCs)
In the event of communication problems, the fault may exist in other parts of the communications network.
The role of the central electronic module is to generally control the communications network and to store diagnostic trouble codes (DTCs) in the event of communication problems between control modules.
If there are diagnostic trouble codes (DTCs) stored for communication problems in the central electronic module, stop the fault tracing and fault trace the central electronic module.
Were diagnostic trouble codes (DTCs) for communication problems stored in the central electronic module?
Yes - DONE
No - No Fault Found

Checking diagnostic trouble codes (DTCs) in the control module for the steering angle sensor
If there are diagnostic trouble codes (DTCs) stored in the control module for the steering angle sensor, these must be fault-traced first.
Were diagnostic trouble codes (DTCs) stored in the control module for the steering angle sensor?
Yes - DONE
No - Checking wiring and terminals
-------------------------------------------------
Checking wiring and terminals
- Ignition off.
Check the brake control module connector. Check for damaged or bent terminal pins. Check for contact resistance and oxidation.
Check the wiring for CAN communication between brake control module terminal #11 (#A11) and terminal #6 (#A36) on the control module for the steering angle sensor and between brake control module terminal #15 (#A15) and terminal #15 (#A45) on the control module for the steering angle sensor. Check for an open-circuit. Check for a short-circuit to ground. Check for a short-circuit to supply voltage.
Check that the wiring is not too close to a source of interference such as a carphone etc.
Remedy as necessary.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
