Steering Column Electronics Control Module -J527-

General Information

The Steering Column Electronics Control Module -J527- includes the following components and cannot be disassembled:

• Airbag Spiral Spring/Return Spring with Slip Ring -F138-
• Steering Angle Sensor -G85-

WARNING

Before working on electronic system and removing the steering wheel the following conditions must be met:

The technician must discharge static electricity. This is accomplished by touching grounded metal like, for example, water pipes, heating pipes, metal carriers or a heater pipe.

If this note is ignored it can result in failure of the control modules during later operation.

• Remove the battery ground cable.
• Wheels must be located in straight ahead position.

If this note is ignored, it can result in failure of the airbag system during later operation.

Note

• Remove the transportation safeguard before assembling if a new Steering Column Electronics Control Module -J527- is being installed.
• Code the new Steering Column Electronics Control Module -J527- after installing it.
• If the steering column switch malfunctions, the coding of the Steering Column Electronics Control Module -J527- must be checked.

Caution

If the universal joint is separated from the steering gear, or the Steering Angle Sensor -G85- is removed, do not perform the following tasks:

• Connecting the battery
• Turning on the ignition
• Turning the steering gear.
• Turning the steering column.

These points must be followed otherwise, it can lead to irreparable damage.

The procedure for removing and installing the Steering Column Electronics Control Module -J527- differs between manufacturers.
