Functions
1. Firing order : 1-5-3-6-2-4
2. The ignition cables are located on the cylinder head cover.
Each ignition coil provides the high voltage to two spark
plugs simultaneously.
- T1/1 : cylinder 2 and 5
- T1/2 : cylinder 3 and 4
- T1/3 : cylinder 1 and 6
Removal & Installation Procedure
1. Disconnect the negative battery cable (1).
2. Remove the ignition cable connector from the ignition cable.
3. Disconnect the secondary spark plug connectors from the
each spark plugs and remove the ignition cable.
Installation Notice 3. The secondary output voltage (5a) is supplied to the No.2
cylinder spark plug through the spark plug connector. The
secondary output voltage (5b) is supplied to the No.5 cylinder
spark plug through the ignition cable. The guide pin (W)
acts as a ground while the ignition cable is operated.
lMake sure that the ignition cables are correctly routed.
lExactly install the ignition cable guide pin into the vehicle
to be grounded.
4. Installation should follow the removal procedure in the
reverse order.
Tightening Torque 9 - 11 Nm

Preheating System Operation
1. Preheating before start.
Preheating time is different by coolant temperature and it is
on until the glow indicator light goes off.
2. Preheating after start.
Preheating continues for max. 60 seconds to rise in
characteristic of warming-up on engine after starting too.
3. Monitoring on glow plug.
Glow plugs are monitored by low current by the micro
processor in control relay respectively while running the
engine.
If glow indicator comes on after starting for about one minute,
it indicates on or several plugs are faulty.
Possible Cause
- One or several glow are faulty Problem
Glow indicator does not come on in preheating
time and comes on after starting the engine.
Glow indicator does not come on while
preheating and after starting engine.
Glow indicator does not come on and engine’s
starting is difficult or does not start at all.
Glow indicator comes on after starting for
about one minute.1

4- Faulty glow indicator
- Faulty circuit of glow indicator
- Faulty control relay
- Circuits short in one or several glow plugs
- Faulty preheating circuits
- Faulty control relay
- One or several glow plugs are faulty

Planet Carrier and Centre Support
To remove the planet carrier and centre support, proceed as
follows.
1. Separate the planet carrier and centre support from the
output shaft. Remove the thrust bearings from the output
shaft and the planet carrier.
2. Separate the centre support from the planet carrier by
rotating it anti-clockwise.
3. Lift the one way clutch from the planet carrier.
4. Remove the circlip retaining the one way clutch outer race
in the planet carrier and remove the race.
5. Remove the one way clutch retainer from the planet carrier.
Pump
Note that the following valves are housed in the pump cover:
lSolenoid 7
lC1 bias valve
lConverter clutch control valve
lConverter clutch regulator valve
lPrimary regulator valve
To remove the pump, proceed as follows.
1. Remove the wiring loom retainer plate and remove
solenoid 7 with a T30 Torx bit.
2. Remove the five washer head bolts from the cover plate
using a multi-point 8 mm socket.
3. Remove the five Torx head screws from the cover plate
(Torx bit No. 30). Note that the odd screw holds the pump
body to the pump body cover.
Notice
Do not strike the converter support tube to loosen the
pump body.
4. Separate the pump body from the pump cover.
5. Lift the cover plate from the cover.
6. Remove the two ball check valves and one spring from
the pump cover.
Notice
Some of the valves and plugs are preloaded by springs
and may unexpectedly fall out of the cover when the pins
are removed.
7. Depress the plug inward and remove the retaining pin for
each of the four valves.
8. Remove the four valves, plugs and springs.
9. Remove the pump gears from the pump body.
10. Remove the lip seal from the front of the pump body.

5A-94 AUTOMATIC TRANSMISSION
ASSEMBLY PROCEDURE
The transmission is assembled in modular fashion and details
of assembly for each module are given under the appropriate
subject. Refer to table 8.1 (at the end of Section 8.3) for the
torque specifications to be applied, and to table 9.10 in section
9.6 for details of all special tools required, when performing
assembly procedures. Technicians overhauling these
transmissions will also require a selection of good quality Torx
bit sockets, in particular numbers 30,40 and 50, and an 8 mm,10
mm and 12 mm double hex socket.
Transmission
Notice
1. Ensure that the B1R circlip is fitted to the case. (If this is not
fitted, the valve will peen its way into and through the
separator plate.)
2. Ensure that the ‘E’ clip is fitted to the cross shaft.
3. Ensure that all aspects of the parking mechanism are
working.
To assemble the transmission, proceed as follows:
1. Turn the transmission case upside down on the bench and
mount it to the transmission cradle No.0555-331895.
2. Install all fittings, plugs and the breather, applying a sealant
where applicable, Tighten the fittings to specifications.
Ensure that the breather is clear, and check that the lube
fitting in the rear of the case is fitted and clear of obstruction.
3. Assemble the B1R valve and spring, and secure with the
irclip. Refer to Ensure that the circlip is completely seated
in its groove.
4. Install the rear servo lever and pivot pin.
Notice
The lever must pivot freely on its pin.
