Connector JAGUAR X308 1998 2.G Workshop Manual

ItemPart NumberDescription
1—Gear selector lever
2—Access blank - Gear-shift interlock solenoid
3—Connector - DLS
4—Dual Linear Switch (DLS)
5—Connector - Park position switch
6—Connector - Illumination module

Selector lever:
Gear selector positions are:
P Transmission mechanically locked, starting available * R Reverse gear N Neutral gear, no power to the rear wheels (starting available) D Drive gear, all 5 forward gears available (see Performance Mode Pushbutton) 4 Upshift to 4th gear only 3 Upshift to 3rd gear only 2 Upshift to 2nd gear only
Gearshift Interlock Manual Override*
The interlock system which locks the sele ctor in P and prevents the ignition key from being removed except when P is
selected, may be manually overridden in the event of an emergency.
1. 1. With the parking brake applied
2. 2. Remove the access blank using a suitable Torx bit
3. 3. Insert a small screwdriver into the vacated hole
4. 4. Push the screwdriver downwards, gently, and hold whilst simultaneously moving the selector from P towards R ,
but do not engage R until the tool has been removed
5. 5. An audible warning may be heard when operation 4 is carried out
6. 6. With the selector in N and the access bl ank replaced, the vehicle may be started
Range Selection
The selector lever transmits operator demand to the transmission and TCM by means of a cable and Dual-Linear
Switch (DLS).
The lever operates the transmission assemb ly selector shaft, only for P R N D , by means of a cable. Movement of the
lever across the gate to 4, 3 and 2 positions disengages th e cable from the selector lever and engages the DLS which
controls gear selection electronically.
Gear selector module:
Provides illumination of the decal relevant to the gear sele cted. This information is provided by CAN from the TCM. Illuminates the security system Active LED on the gear selector surround, in response to an output from the BPM.

TEST CONDITIONSDETAILS/RESULTS/ACTIONS
A1: RETRIEVE DTCS
• NOTE: Battery and or ECM disconnection prior to scanning wi
ll erase all data, ensure that the correct DTC is present.
Connect the scan tool 1
Have the DTC(s) and freeze frame data been recorded?
Yes GO to A2
A2: STATUS / RELATIONSHIP CHECK
Move the selector lever sl owly from P to 2 and back,
noting the illumination / positi on relationship as follows: 1
Does state illumination match the lever position in each
direction of travel?
Yes
GO to A4
No GO to A3
No With lever at D (when moving from 2 to P ) is 3 or 4
illuminated?
Yes GO to A3

Align the drive peg and lower sliding block of the switch to
the mating components of the selector mechanism.

2. Install the four screws, bu t do not fully tighten.
Remove the Ty-Strap from the dual linear switch.
Use the manual release and repo sition the selector to 'N'
for installation of the selector cable.

3. Connect the electrical connector to the linear switch.

4. Assemble the cable to the gear shift assembly.
1. Locate the outer cable and fit the inner cable to the gear selector arm. Tighten to 22-28 Nm.
2. Position the abutment nuts to the approximate position, but do not tighten.
5. NOTE: When setting the selector cable, ensure that the
selector lever on the transmission ca sing is still in the 'N' position.

Adjust the selector cable from inside the vehicle.
1. Confirm that the selector lever is in the 'N' position.
2. Adjust the nuts to lock against the bracket without
