Dynamic Suspension - Geometry Setting Mode

No: LA204-007
Issue: 1
Date: 03 Oct 2006

SECTION: 204-00 - SUSPENSION SYSTEM

Dynamic Suspension Geometry Setting Mode

AFFECTED VEHICLE RANGE:

LR3 (LA)

VIN: All with EAS

CONDITION SUMMARY:

ACTIVATING "TIGHT TOLERANCE MODE" TO ADJUST VEHICLE GEOMETRY

Situation:
New functionality has been added to the Integrated Diagnostic System (I DS) that allows the vehicle dynamic suspension (electronic air suspension) to be temporarily set in a geometry setting mode. The "Tight Tolerance Mode" changes the suspension ride height tolerances to a lower/tighter range of +/- 5 mm (+/- 0.2 in) to allow for accurate geometry adjustment.

Variations in geometry setting results have led to the introduction of the "Tight Tolerance Mode" to improve setting consistency.

NOTE:
The "Tight Tolerance Mode" is set using IDS. The IDS unit does not need to remain connected while the geometry is being adjusted.

NOTE:
Activating the "Tight Tolerance Mode" will cause the air suspension warning lamp to be illuminated and the DTC CIA00-54 to be logged. When the setting mode is de-activated using IDS the warning lamp is extinguished and the DTC is cleared automatically.

Action:
Should the vehicle geometry settings require adjustment, refer to the Repair Procedure detailed in this bulletin to temporarily activate the "Tight Tolerance Mode" and adjust vehicle geometry using workshop manual procedures.

PARTS:

No parts required.

TOOLS:

IDS DVD/03 or later software installed.

WARRANTY:

NOTE:
Repair procedures are under constant review, and therefore times are subject to change; those quoted here must be taken as guidance only. Always refer to DDW to obtain the latest repair time.





DDW requires the use of causal part numbers.

Labor only claims must show the causal part number with a quantity of zero.

Normal warranty policy and procedures apply.





NOTE:
Labor operation 60.90.18 and associated time of 0.2 hours to activate and deactivate Tight Tolerance mode replaces the need to check or re-calibrate the air suspension system. The labor time of 1.1 hours to calibrate the air suspension system has been removed and the labor time of 0.2 hours to activate/deactivate Tight Tolerance mode has been included in the revised labor times listed in Table 1.

^ Labor operation 60.90.18 should not be claimed as a separate SRO on any warranty claim where the geometry has been checked or adjusted and claimed by a Land Rover Retailer.

^ Labor operation 60.90.18 should only be claimed as a separate SRO when the Retailer has used IDS to activate and deactivate Tight Tolerance mode in order to prepare the vehicle for sublet to an outside repair facility for geometry adjustments.
