STEERING COLUMN ELECTRONIC SYSTEMS CONTROL MODULE

Description

The steering column electronic systems control module is a part of the steering column switch module. The steering column switch module consists of

  1. Left and right steering column switch
  2. Airbag spiral spring
  3. Steering angle sensor
  4. Ignition/starter switch
  5. Steering column electronic systems control module

The steering column electronic systems control module exchanges data between vehicle control modules (e.g. vehicle electrical system control module) and steering column modules (e.g. steering column switch) and steering wheel modules (e.g. airbag).

In addition, multi-function steering wheel button signals are process and relayed via CAN BUS.

Fault finding is performed via Guided Fault Finding. Refer to => .

Steering column switch module, removing and installing, refer to [For transmission(s) 02E] [For engine(s) CBRA, BPY, CETA, CCTA, CEPB, CDMA] Description and Operation .

Repair to CAN bus lines, refer to General Information .
