Drive shaft JAGUAR X308 1998 2.G Workshop Manual

Operation
• NOTE: The rotary position switch is NOT adjustable.
The position of the gear selector lever is detected by the range sensor; a system which consists of two sensors (switch
systems). 1. 1. The rotary position switch, which is located on the RH side of the transmission case and is coaxial with the
selector shaft.
2. 2. The D to 4 (micro) switch, which is mounted in the 'J gate' assembly.
When the selector is moved across the ga te to engage 4, or back from that side towards D the selector cable does not
move. In order that this change of state be registered by the TCM the D to 4 switch is incorporated.
The rotary switch in isolation provides a 4-bit code, which, when added to the D to 4 switch becomes a 5-bit code. The TCM
will make a failure judgement if it detects an 'illegal' code.

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.
