SERVICE ACTION ENGINE HARNESS INSPECTION / REPAIR

SERVICE CAMPAIGN BULLETIN

Reference Number(s): SB276, Date of Issue: March 16, 2005

LAND ROVER:	Range Rover (LP)
ISSUE:	1
SECTION:	General Info
AFFECTED VEHICLES:	Range Rover (LP) XA403796 to 1A458539

SITUATION:

ENGINE HARNESS DAMAGE / CHAFE

The original harness routing path can permit the engine harness to chafe on the engine compartment fuse box bracket. Extended chafing can result in electrical short or system malfunction.

RESOLUTION:

INSPECT AND REPOSITION HARNESS

At the next service opportunity inspect the harness for damage. If damage is determined, repair the harness using harness repair kits. If damage is severe, contact the Land Rover HelpLine for consultation and authorization to replace the harness. Route the engine harness as specified in this Bulletin.

PARTS INFORMATION:

NOTE: Supply of engine harnesses is extremely limited. DO NOT order harnesses for stock.

Contact the Technical HelpLine (888-577-8577 Option 3) to determine if a replacement harness is required for repair after inspection indicates that it MIGHT be.
* VIN ranges are approximate. A label with part number is fitted to the harness adjacent to the battery box. Prior to ordering a replacement harness the harness part number on the vehicle must be checked to ensure that the correct harness is ordered.
NOTE: Repair connectors are supplied in packs of five. Due to limited availability, please restrict parts order to one pack of each of these part numbers.

REPAIR PROCEDURE

INSPECT AND RE-ROUTE ENGINE HARNESS

Release and remove the battery cover.
CAUTION: After the ignition is switched off, the navigation computer remains 'on' for approximately 55 seconds. It then performs a memory back-up operation for approximately 5 seconds before shutting down into 'sleep' mode.
If the vehicle battery is disconnected during this critical 5-second backup period, it can cause a memory error in the navigation computer. This can render the computer unusable, so that when power is reapplied, the satellite navigation system will not power up, giving a blank screen.
Refer to Service Action Bulletin H269 for information governing battery removal.
After waiting two minutes from ignition shut-off, disconnect the battery ground cable.
Remove 3 bolts securing the engine compartment fuse box to the retaining brackets. (Fig 1 )

Fig 1: Removing Bolts Securing Engine Compartment Fuse Box To Retaining Brackets

Move the fuse box aside.
Determine if the harness lead is incorrectly routed between the alarm horn and fuse box bracket. (Fig 2 )
If incorrectly routed, inspect the engine harness for damage caused by a foul condition on the fuse box mounting bracket.

Fig 2: Identifying Incorrect Routing Of Harness Lead

NOTE: A thorough examination of the engine harness will ensure that no other damage has occurred as the result of harness routing.
If the engine harness is damaged but repairable, perform the following repair process:
- Remove outer cable sheathing to exposed damaged wires.
- Repair individual leads using repair wires of correct cross section.
- Insulate the repaired engine harness damaged area using electrical tape.
If it is believed that the engine harness is beyond repair consult with the Technical HelpLine to verify that the replacement option is the best solution.
NOTE: GTR lookup sequence is as follows: GTR Home > NAS > Service Information/ LP Range Rover/2002 > Workshop Manuals > Range Rover > Bookmark "86 - Electrical" > "HARNESS - ENGINE - V8 - FROM 99MY" link
If it is determined that the harness is beyond repair, refer to GTR section 86.70.17 and replace the harness.
During the repair or replacement process, perform the following:
- Disconnect the alarm horn connector.
- Position the engine harness between the battery box and the alarm horn. (Fig 3 and Fig 4 )
- Ensure the engine harness is situated below the alarm horn connector.
- Connect the alarm horn connector.
Position the fuse box to the fuse box retaining brackets.
Verify that the wiring to the fuse box is not trapped between the fuse box and bracket.
Start the three fuse box attachment bolts and tighten to 2.5 Nm (1.8 lbf.ft).
Connect the battery ground cable.
Install and secure the battery cover.
