Removal and Installation
CAUTION:
As the internal mechanism of the idler gear must first of all,
and always, be set by a bolt when removing the timing chain
before removing the fuel injection pump and timing gear, fol-
low the procedures on EM-38, ªRemoval of timing chain after
setting idler gearº, ªElectronic controlled fuel injection pumpº.
IThis chapter will deal with the summary of removing the timing
chain before removing the camshaft and cylinder head.
Removal
1. Remove the following parts.
IEngine cover
I Intercooler
I Air inlet pipe
I Throttle body
I Rocker cover
I Spill tube
I Coolant (Drain)
I Radiator upper hose
I Water outlet
I Radiator shroud
I Cooling fan
I Auxiliary belt
I Vacuum pipe
I Vacuum pump

TCM FUNCTION
The function of the TCM is to:
IReceive input signals sent from various switches and sensors.
I Determine required line pressure, shifting point, lock-up operation, and engine brake operation.
I Send required output signals to the respective solenoids.
INPUT/OUTPUT SIGNAL OF TCM
Sensors and solenoid valves Function
Input Park/neutral position switch
Detects select lever position and sends a signal to TCM.
Throttle (accelerator) position sensor Detects throttle valve position and sends a signal to TCM.
Closed throttle position switch Detects throttle valve's fully-closed position and sends a signal to TCM.
Wide open throttle position switch Detects a throttle valve position of greater than 1/2 of full throttle and sends a
signal to TCM.
Engine speed signal From ECM.
A/T fluid temperature sensor Detects transmission fluid temperature and sends a signal to TCM.
Revolution sensor Detects output shaft rpm and sends a signal to TCM.
Vehicle speed sensor Used as an auxiliary vehicle speed sensor. Sends a signal when revolution sen-
sor (installed on transmission) malfunctions.
Overdrive control switch
A/T mode switch Sends a signal, which prohibits a shift to ªD
4º (overdrive) position, to the TCM.
Output Shift solenoid valve A/B
Selects shifting point suited to driving conditions in relation to a signal sent from
TCM.
Line pressure solenoid valve Regulates (or decreases) line pressure suited to driving conditions in relation to
a signal sent from TCM.
Torque converter clutch solenoid valve Regulates (or decreases) lock-up pressure suited to driving conditions in relation
to a signal sent from TCM.
Overrun clutch solenoid valve Controls an ªengine brakeº effect suited to driving conditions in relation to a sig-
nal sent from TCM.
O/D OFF indicator lamp
SPORT indicator lamp Shows TCM malfunctions, when A/T control components malfunction.

Vehicle Speed Sensor×MTR
DESCRIPTION
The vehicle speed sensor×MTR is built into the speedometer
assembly. The sensor functions as an auxiliary device to the revo-
lution sensor when it is malfunctioning. The TCM will then use a
signal sent from the vehicle speed sensor×MTR.
ON BOARD DIAGNOSIS LOGIC
Diagnostic trouble codeMalfunction is detected when ... Check items
(Possible cause)
: VHCL SPEED SEN×MTR TCM does not receive the proper volt-
age signal from the sensor.I
Harness or connectors
(The sensor circuit is open or
shorted.)
I Vehicle speed sensor
: 2nd judgement flicker
SELF-DIAGNOSIS CODE CONFIRMATION PROCEDURE
After the repair, perform the following procedure to confirm the
malfunction is eliminated.
1) Start engine.
2) Select ªSELF-DIAG RESULTSº mode with CONSULT-II.
3) Drive vehicle under the following conditions:
Selector lever in ªDº position and vehicle speed higher
than 20 km/h (12 MPH).

1) Start engine.
2) Drive vehicle under the following conditions:
Selector lever in ªDº position and vehicle speed higher
than 20 km/h (12 MPH).
3) Perform self-diagnosis. Refer to SELF-DIAGNOSTIC PROCEDURE (Without
CONSULT-II), AT-15.

Inspection
SPEAKER
1. Disconnect speaker harness connector.
2. Measure the resistance between speaker terminalsq
1andq2.
I The resistance should be2-4 W.
3. Using jumper wires, momentarily connect a 9V battery between speaker terminals q
1andq2.
I A momentary hum or pop should be heard.
ANTENNA
Using a jumper wire, clip an auxiliary ground between antenna and body.
IIf reception improves, check antenna ground (at body surface).
I If reception does not improve, check main feeder cable for short circuit or open circuit.
RADIO
All voltage inspections are made with:
IIgnition switch ON or ACC
I Radio ON
I Radio connected (If removed for inspection, supply a ground to the case using a jumper wire.)
