2. SPEED SENSOR SIGNAL
(a) Check the speed sensor signal.
(1) Turn the ignition switch OFF.
(2) Using SST, connect terminals Ts and E
1 of DLC1.
SST 09843 ± 18020
(3) Start the engine.
(4) Check that the ABS warning light blinks.
HINT:
If the ABS warning light does not blink, inspect the ABS warning
light circuit (See page DI±213).
(5) Drive vehicle straight forward.
HINT:
Drive vehicle faster than 45 km/h (28 mph) for several seconds.
(6) Stop the vehicle.
(7) Using SST, connect terminals Tc and E
1 of DLC1.
SST 09843 ± 18020
(8) Read the number of blinks of the ABS warning light.
HINT:

See the list of DTC shown on the next page.

If every sensor is normal, a normal code is output (A cycle
of 0.25 sec. ON and 0.25 sec. OFF is repeated).

If 2 or more malfunctions are indicated at the same time,
the lowest numbered code will be displayed 1st.
(9) After doing the check, disconnect the SST from ter-
minals Ts and E
1, Tc and E1 of DLC1, and turn igni-
tion switch OFF.

ABS Warning Light Circuit
CIRCUIT DESCRIPTION
If the ECU detects trouble, it lights the ABS warning light while at the same time prohibiting ABS control. At
this time, the ECU records a DTC in memory.
After removing the short pin of the DLC1, connect terminals Tc and E
1 of the DLC1 or DLC2 to make the
ABS warning light blink and output the DTC.

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.

Turn ignition switch ON.
(2): For check No.4

Jack up the vehicle.

Start the engine.

Shift to D position.
(a) Pull the control switch to SET/COAST or RES/ACC posi-
tion and hold it down or up (1).
(b) Push the main switch ON (2).
(c) Check that the CRUISE MAIN indicator light blinks twice
or 3 times repeatedly after 3 seconds.

(e) Operate each switch as listed in the table below.
(f) Read the blinking pattern of the CRUISE MAIN indicator
light.
(g) After performing the check, turn the main switch OFF.
HINT:
When 2 or more signals are input to the ECU, the lowest num-
bered code will be displayed first.

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.

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).

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
