The Drive-to-fourth switch:
Detects when the gear selector lever is moved from Drive to Fourth. Is hard-wired to the transmission control module.
The Neutral position switch:
Is hard-wired to the body processor module. Detects when the gear selector lever is moved to the Neutral position.
The Park position switch:
Is hard-wired to the body processor module. Detects when the gear selector leve r is moved to the Park position.
The gear selector module:
Provides illumination of the gear sele ctor surround, which is dimmable via a CA N signal from the instrument cluster. Provides red illumination, on the gear selector surround, of the gear selected, by CAN signals from the instrument
cluster.
Illuminates the security system Active LED on the gear se lector surround, in response to an input from the body
processor module.
Is connected to the fascia harness via a 12-way connector. Refer to Connec tor Pins Identification, 307-01A.
The gear selector interlock solenoid:
Prevents the gear selector lever from be ing moved from the Park position, unless th e ignition switch is in position II,
and the brake pedal is depressed.
Is controlled by an input from the body processor module.
The seven gear selector positions are:
P : The transmission is mechanically locked (starting available). R : Reverse gear. N : No power to the rear wh eels (starting available). D : All 5 forward gears available. 4 : Upshift to 4th gear only. 3 : Upshift to 3rd gear only. 2 : Upshift to 2nd gear only.
Performance Mode Pushbutton

The performance mode pushbutton:
Is mounted on the gear selector surround. Selects Normal or Sport mode when pressed by the driver. Is illuminated when Sport mode is selected.

Move the selector lever slowly 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
No GO to A5
No With lever moved from P , to position 4 , is D illuminated?
Yes GO to A4
No GO to A5
A3: CHECK SELECTOR CABLE ADJUSTMENT
Verify and correct as requ ired the selector cable
adjustment 1

307-05A and test the system for normal operation.
A4: CHECK HARNESS SIGNAL CONTINUITY - D TO 4 SWITCH

No GO to A5
No With lever moved from P , to position 4 , is D illuminated?
Yes GO to A4
No GO to A5
A3: CHECK SELECTOR CABLE OR LINEAR SWITCH ADJUSTMENT

switch adjustment 1
OK?
Yes GO to A4
No Correct adjustment error, see 44.15.07 Workshop Manual
307-05B and test the system for normal operation.

14. Where the voltages at step 12 are the same as the voltages
taken at step 10, contin ue to step 16 below.
15. Rotate the adjustment nut clockwise (as viewed from the
front of the vehicle) until the same voltages are indicated as in
step 10. Continue to turn thro ugh a part revolution until the
sides of the nut are vertical. Tu rn through a further 90 degrees,
then fully insert the nut into the abutment bracket.
