Ts Terminal Circuit
CIRCUIT DESCRIPTION
The sensor check circuit detects abnormalities in the speed sensor signal which cannot be detected with
the DTC check.
Connecting terminals Ts and E
1 of the DLC1 in the engine compartment starts the check.
WIRING DIAGRAM
INSPECTION PROCEDURE
1 Check voltage between terminals Ts and E1 of DLC1.
CHECK:
(a) Turn the ignition switch ON.
(b) Measure voltage between terminals Ts and E
1 of DLC1.
OK:
Voltage: 10 ± 14 V
OK If ABS warning light does not blink even after Ts
and E
1 are connected, the ECU may be defec-
tive.

CIRCUIT DESCRIPTION
When the clutch pedal is depressed, the clutch switch sends a signal to the cruise control ECU. When the
signal is input to the cruise control ECU during cruise control driving, the cruise control ECU cancels cruise
control.

PRE±CHECK
1. DIAGNOSIS SYSTEM
(a) Description
ECM controls the function of immobiliser on this vehicle.
Data of the immobiliser or DTC can be read form DLC3 of
the vehicle. When a trouble occurs in immobiliser, MIL
does not light ON but DTC inspection is performed.
Therefore when there seems to be a trouble with immobi-
liser, use TOYOTA hand±held tester or SST to check and
troubleshoot it.
(b) DLC3 INSPECTION
The vehicle's ECM uses ISO 9141±2 for communication.
The terminal arrangement of DLC3 complies with
SAEJ1962 and matches the ISO 9141±2 format.
Tester connectionconditionSpecified condition
7 (Bus
Line) ± 5 (Signal ground)During communicationPulse generation
4 (chassis Ground) ± BodyAlways1 W or less
5 (Signal Ground) ± BodyAlways1 W or less
16 (B+) ± BodyAlways9 ± 14 V
HINT:
If your display shows ºUNABLE TO CONNECT TO VEHICLEº
when you have connected the cable of OBD ll scan tool or TOY-
OTA hand±held tester to DLC3, turned the ignition switch ON
and operated the scan tool, there is a problem on the vehicle
side or tool side.
(1) If communication is normal when the tool is con-
nected to another vehicle, inspect DLC3 on the orig-
inal vehicle.
(2) If communication is still impossible when the tool is
connected to another vehicle, the problem is prob-
ably in the tool itself, so consult the Service Depart-
ment listed in the tool's instruction manual.

HINT:
As a large amount of exhaust gas enters, the engine will misfire
slightly.
(g) Remove the vacuum gauge, and reconnect the vacuum
hoses to the proper locations.
(h) Inspect the EGR valve.
(1) Apply vacuum directly to the EGR valve with the en-
gine idling.
(2) Check that the engine runs rough or dies.
(3) Reconnect the vacuum hoses to the proper loca-
tions.
HINT:
As exhaust gas is increasingly recirculated, the engine will start
to misfire.
(i) Remove the SST from the DLC1.
SST 09843±18020
2. INSPECT EGR VACUUM MODULATOR
(a) Disconnect the vacuum hoses from ports P, Q and R of
the EGR vacuum modulator.
(b) Block ports P and R with your finger.
(c) Blow air into port Q, and check that the air passes through
to the air filter side freely.
(d) Start the engine, and maintain speed at 2,500 rpm.
(e) Repeat the above test. Check that there is a strong resis-
tance to air flow.
(f) Reconnect the vacuum hoses to the proper locations.

valve clearance. (See step (a))
4. ADJUST VALVE CLEARANCE
(a) Remove the adjusting shim.
(1) Turn the crankshaft so that the cam lobe of the cam-
shaft on the adjusting valve points upward.
(2) Position the notch of the valve lifter facing the spark
plug side.
(3) Using SST (A), press down the valve lifter and place
SST (B) between the camshaft and valve lifter. Re-
move SST (A).
SST 09248±55040 (09248±05410, 09248±05420)
HINT:
Apply SST (B) at slight angle on the side marked with º9º, at the
position shown in the illustration.
(4) Remove the adjusting shim with a small screwdriver
and magnetic finger.
(b) Determine the replacement adjusting shim size by follow-
ing the Formula or Charts:
(1) Using a micrometer, measure the thickness of the
removed shim.
(2) Calculate the thickness of a new shim so that the
valve clearance comes within specified value.
T ........... Thickness of removed shim
A ........... Measured valve clearance
N ........... Thickness of new shim
Intake: N = T + (A ± 0.24 mm (0.009 in.))

1. WARM UP ENGINE
Allow the engine to warm up to normal operating temperature.
2. CONNECT TOYOTA HAND±HELD TESTER OR OBDII

(a) Remove the fuse cover on the instrument panel.
(b) Connect a TOYOTA hand±held tester or OBDII scan tool
to the DLC3.
(c) Please refer to the TOYOTA hand±held tester or OBDII
scan tool operator's manual for further details.
3. CONNECT TIMING LIGHT TO ENGINE
4. INSPECT IGNITION TIMING
(a) Using SST, connect terminals TE1 and E1 of the DLC1.
SST 09843±18020
HINT:
After engine rpm is kept at 1,000 ± 1,300 rpm for 5 seconds,
check that it returns to idle speed.
(b) Using a timing light, check the ignition timing.
Ignition timing: 8 ± 12° BTDC @ idle
(Transmission in neutral position)
(c) Remove the SST from the DLC1.
SST 09843±18020
5. FURTHER CHECK IGNITION TIMING
Ignition timing: 0 ± 10° BTDC @ idle
(Transmission in neutral position)
HINT:
The timing mark moves in a range between 0° and 10°.
