REPAIR PROCEDURE

INSTALL COLUMN COWL USING NEW PROCEDURE

NOTE:

The steering column cowl or "nacelle" procedure in the Workshop Manual (57.40.29) will be updated at the next available opportunity to reflect

the procedure detailed below.

1. Fully extend the steering column for access. Wheel removal is not required.

113

2. Remove three Torx screws securing steering column cowl. (Figure 1)

3. Release the cowl from the clips securing the assembly to the column extension bellows.

4. Remove the steering column cowl.

5. Push the steering column extension bellows fully toward the front of the vehicle.

CAUTION:

The lower half of the cowl must not come in contact with the steering wheel.

6. Position the lower half of the cowl to the column assembly.

7. Install and tighten the two T25 Torx screws.

8. Install the upper half of the cowl.

9. Verify that the clips engage with the lower half.

CAUTION:

The upper part of the cowl must not come in contact with the steering wheel.

10. Verify that there is no contact between the upper or lower cowl components and the steering wheel.

11. Secure the upper half of the cowl into position with the remaining T20 Torx screw.

12. Install and secure steering column extension bellows to the assembled cowl.

Rocker Arm Rattle/Tapping Sound

AFFECTED VEHICLE RANGE:

RANGE ROVER (LP) WA382672 to YA437311

DISCOVERY SERIES II (LT)Up to YA265404

DISCOVERY (U) WA753113 to XA795263

SITUATION:

NOISE FROM ENGINE VALVE TRAIN/ROCKER ARMS

Customer complaints of a rattling/tapping noise from the engine found to originate from rocker shaft area may be the result of the hardened push-rod

cup being insecure in the rocker arm.

RESOLUTION:

NOTE:

This bulletin supersedes and replaces TIB 12/01/981NAS.

INSPECT AND REPLACE ROCKER ARMS

Investigate customer complaints of valve rattling/tapping noise on vehicles within the above VIN ranges and identify rocker arms with loose

push-rod cups. If noisy or loose rocker arms are encountered during the inspection, replace all rocker arms with updated parts.

PARTS INFORMATION

WARRANTY CLAIMS

Normal warranty policy and procedures apply.

152

REPAIR PROCEDURE:

DETERMINE FAULTY ROCKER ARMS AND REPLACE

1. Refer to Workshop Manual, Section 12, Engine Repairs, and remove both rocker covers.

2. Determine that rocker arms with loose cups are the source of the noise.

3. Locate the rocker arm casting date code on each rocker arm.

CAUTION:

Only rocker arms with date codes '00' may be used to repair valve trains. Use of early production rocker arms may result in a reoccurrence

of the problem.

4. Refer to Overhaul Manual LRL0004ENG and replace all rocker arms manufactured prior to a '00' date code with new rocker arms having date

code '00' or above. (Figure 1)

5. Assemble and install rocker arm assemblies.

6. Install rocker arm covers.

7. Start the engine and confirm that the rattling/tapping noise has been resolved.

Battery - Dead/Fails to Maintain A Charge

No: 86/01/00/NAS

Ref:

Issue: 1

Date: 03/03/00

Quiescent Current Draw

AFFECTED VEHICLE RANGE:

All Vehicles

SITUATION:

BATTERY IS DEAD OR FAILS TO MAINTAIN CHARGE

NOTE:

"Quiescent current" is current drawn from the battery by vehicle components that require power when the key is in the "off" position. The draw

may include the radio, clock, security system and ECU memory. It will also vary depending on the "sleep" status of various ECUs.

Some electronics, including plips from other vehicles in the vicinity, can "awaken" an ECU. When testing avoid the use of plips in the vicinity. If

consistently and repeatedly "awakened" over an extended time, the ECU quiescent draw can drain a battery.

A battery will self discharge at a rate between 0.1 - 1% at 20锟斤拷C (68锟斤拷F) depending on the age and condition of the battery. The self discharge rate will

INCREASE 1% for every 10锟斤拷C (19锟斤拷F) increase in temperature

Dirt and moisture on the top surface of the battery will also increase the discharge rate.

A quiescent current draw that exceeds specification can cause excessive battery drain while the engine is off. This may result in a dead battery or

inability of the battery to maintain a charge.

RESOLUTION:

TEST VEHICLE FOR EXCESSIVE QUIESCENT CURRENT DRAW

When a vehicle exhibits the above symptoms, measure the current from the battery after all vehicle systems have been shut down. Verify that the

current is less than or equal to the specified current level for that vehicle in the Repair Procedure section of this TIB.

PARTS INFORMATION:

No parts are necessary.

WARRANTY CLAIMS:

86.60.89126 Time 0.40 hrs.

Measure quiescent current draw from battery

FAULT CODE: T

Normal warranty policy and procedures apply

REPAIR PROCEDURE

MEASURE QUIESCENT CURRENT LEVEL

1. Verify that the battery is fully charged.

2. Remove key from ignition lock.

3. Open hood.

4. Disconnect bonnet switch.

5. Close all doors.

6. Verify that all interior lights have extinguished.

7. Lock vehicle with remote.

NOTE:

Ensure that the vehicle electrical system remains powered throughout the following steps.

8. Connect a suitable ammeter between the battery and vehicle electrical system.

9. Wait 30 minutes for all on-board systems to power down. In some cases a Discovery Series II may take up to 60 minutes to completely power

down.

NOTE:

Any accessories fitted to the vehicle with a permanent battery connection, will adversely affect quiescent current. They should be

disconnected before testing the vehicle

10. Measure the current level between the battery and vehicle electrical system.

11. Verify that the current levels recorded are less than those specified for that vehicle in the table.

12. If current levels exceed those specified in the above table, it is necessary to evaluate each electrical subsystem to locate the source of the

excessive current draw.
