Module, Electronic Steering Lock (ESL): Installation
When the ESL requires replacement the RF-Hub must also be replaced.
To avoid serious or fatal injury on vehicles equipped with airbags, disable the Supplemental Restraint System (SRS) before attempting any steering wheel, steering column, airbag, Occupant Classification System (OCS), seat belt tensioner, impact sensor or instrument panel component diagnosis or service. Disconnect and isolate the battery negative (ground) cable, then wait two minutes for the system capacitor to discharge before performing further diagnosis or service. This is the only sure way to disable the SRS. Failure to follow these instructions may result in accidental airbag deployment.
- Carefully inspect the shaft lock module (also known as the Electronic Steering Column Lock/ESCL or the Elektronische Lenkungs Verriegelung/ELV) interface area of the module, the steering shaft and the steering column housing for damage or debris. Remove debris or replace damaged components that could hinder proper shaft lock module operation as required.
- Position the shaft lock module (3) onto the steering column housing (1).
- Install and tighten two new tamper resistant screws (2) to secure the shaft lock module to the steering column housing. Tighten the screws until the heads shear off.
- Install the steering column into the vehicle. Refer to COLUMN, INSTALLATION .
- Do not connect the negative battery cable at this time. The Supplemental Restraint System (SRS) Verification Test procedure should be performed following service of any SRS component. Refer to SUPPLEMENTAL RESTRAINT SYSTEM VERIFICATION TEST .
If this Electronic Control Unit (ECU) is being replaced with a new unit, a diagnostic scan tool MUST be used to determine if alignment of the PROXI configuration data into the new ECU is needed. If PROXI alignment is needed, follow the routine outlined in the diagnostic scan tool for PROXI Configuration Alignment under the Body Control Module (BCM) Miscellaneous Functions menu.
