Driver Air Bag Module

Trustmark Authoring Standards (TAS) Repair Procedures

NOTE: TAS style procedures can be identified by steps that have no accompanying step text and the magenta color of the electrical connectors and fasteners such as nuts, bolts, clamps or clips.

A TAS removal and installation procedure uses a sequence of color illustrations to indicate the order to be followed when removing/disassembling or installing/assembling a component.

Specification data
Specification procedures will only contain technical data that is not already part of a repair procedure.

Sequence of tasks
If components must be removed or installed in a specific sequence, the sequence will be identified numerically in a graphic and the corresponding text will be numbered accordingly.

Special Tools, Equipment, Materials and Torque Figures

Special tools will be shown with the tool numbers in the illustration. The special tool numbers, general equipment, materials and torque figures used for the procedure step will be shown in the text column.

TAS Graphics

Colors used in the graphic are as follows:
Blue - Component to be removed/installed or disassembled/assembled.
Green and Brown - Additional components that need to be removed/installed or disassembled/assembled prior to the target component.
Yellow - Component that is touched or affected in a way but remains in the vehicle. It may be detached, attached, moved, modified, checked, adjusted etc.
Magenta - Electrical connectors and fasteners such as nuts, bolts, clamps and clips.
Pale Blue - Special tool(s) and general equipment.

One illustration may have multiple steps assigned to it.

Numbered pointers are used to indicate the number of electrical connectors and fasteners such as nuts, bolts, clamps and clips.

Items in the illustration can be transparent or use cutouts to show hidden details.

Supplemental Restraint System - Driver Air Bag Module

Removal and Installation

Removal

WARNINGS:
- Allow a period of 10 minutes to elapse after disconnecting the battery before undertaking any work on the SRS.
- Always wear safety glasses when repairing an air bag supplemental restraint system (SRS) vehicle and when handling an air bag module.
- Take extra care when handling supplemental restraint system (SRS) components.
- To avoid accidental deployment and possible personal injury, the backup power supply must be depleted before repairing or replacing any air bag supplementary restraints system (SRS) components. To deplete the backup power supply energy, disconnect the battery ground cable and wait for one minute. Failure to follow this instruction may result in personal injury.
- Always disconnect both battery cables before beginning work on the SRS system. Disconnect the ground cable first. Never reverse connect the battery.
- Make sure all personnel are a minimum of 15 Meters (50 Feet) away from the SRS component. Failure to follow this instruction may result in personal injury.
- When repairing an SRS system, only use genuine new parts.

CAUTION: Make sure the wires are not twisted before connecting them to the airbag module. Once connected do not rotate the airbag as this will cause the wires to twist, which can lead to harness damage and SRS faults.

NOTE:
- Some variation in the illustrations may occur, but the essential information is always correct.
- If the SRS component is to be replaced, the bar code of the new unit must be recorded.

1. Refer to: Specifications.

2. NOTE: The steering wheel is shown removed for clarity.

5. CAUTION: Take extra care not to damage the wiring harnesses.

Installation

1. CAUTION: Take extra care not to damage the wiring harnesses.

NOTE: Make sure that the connector wiring is routed correctly in the clips.

2. WARNING: Driver air bag module installation can be confirmed by hearing 3 audible clicks, 1 for each clip.

CAUTION: Take extra care not to damage the wiring harnesses.

3. If a new component has been installed, configure using Land Rover approved diagnostic equipment.
4. Refer to: Specifications.
