Ensure the four wheels are off the ground
before performing the starting test.
4 W ith the ignition switched to the ON position, check if the engine can only be started in the Park and Neutral shift selector positions and ensure the back-up lamps illuminate when Reverse is selected. A further minor adjustment
may be required to achieve this state.
NOTE
To gain access to the rear attaching screw (11) it
will be necessary to remove the connector.
5 After the switch has been adjusted, tighten the rear attaching screw (11) to the correct torque specification. Neutral start and back-up lamp switch
attaching screw torque specification .................. 25.0 Nm
6 Reinstall the connector and the CPA securing pin.
7 Remove the switch front attaching screw (1).
8 Install the heat shield (3) and tighten the attaching screws (1 and 2) to the correct torque specification.
Heat shield front attaching screw
torque specification ............................................ 25.0 Nm
Heat shield rear attaching screw torque specification ..............................................9.0 Nm
9 Lower the vehicle to the ground and re-check the operation of the neutral start and back-up lamp switch. The vehicle must start only with the shift selector in the Park or Neutral positions and the back-up lamps should only
illuminate when Reverse is selected.
3.5 Vehicle Speed Sensor
NOTE
For the speed sensor fitted to four wheel drive
vehicles (4WD), refer to 7D Transfer Case and
Adaptor Housing.

1 Raise the vehicle and support in a safe manner, refer
to 0A General Information for the location of support
points.
2 Disconnect connector (1) from the vehicle speed sensor (2).
3 Remove the bolt (3) attaching the speed sensor to the transmission extension housing.

as required.
10 As a security check, push and clip each verification disc into place over the quick-connect fittings. If difficulty is experienced, repeat the installation process until the verification disc can be clipped into place over the radiator
quick-connect fitting.
11 Snap the outlet cooler line (4) in the clip (5) of the radiator fan shroud.
12 Ensure the routeing of the cooler lines is correct and there is no fouling of the lines.
13 Tighten the screw attaching the cooler lines bracket to the correct torque specifications.
Transmission cooler lines bracket
attaching screw torque specification .................. 23.0 Nm
14 If required, top up the transmission fluid level (cold).
15 Start the engine and check for any fluid leak at the fittings. If a leak is found, stop the engine and rectify the leak.
16 Check and top up the transmission fluid to the correct level as required, refer to 2.1 Transmission Fluid.

Disconnection of the battery affects certain
vehicle electronic systems. Refer to 6D1-3
Battery, before disconnecting the battery.
1 Disconnect the battery ground lead.
2 Raise the vehicle and support in a safe manner, refer to 0A General Information for the location of support points.
3 Remove the heat shield from the neutral start and back-up lamp switch, gently prise the selector cable from the transmission external manual shaft linkage and remove the selector cable from the bracket, refer to
3.3 Selector Cable Assembly.
4 Disconnect the harness connectors from the following:
a Vehicle speed sensor, refer to 3.5 Vehicle Speed Sensor.
b Neutral start and back-up switch, refer to 3.4 Neutral Start and Back-up Lamp Switch.
c For the following on four wheel drive vehicles (4W D), refer to 7D Transfer Case and Adaptor Housing:
• neutral switch,
• 2WD – 4WD shift actuator switch,
• speed sensor.
NOTE
If the battery is connected, avoid turning the
ignition switch to the ON position, as the transfer
case control module (TTCM) must first be
removed (memory to be cleared as Check 4W D
Indicator will light).
5 Remove the following components: a Front and centre exhaust assemblies, refer to 6F Exhaust System.
