PRE−CHECK
1. DIAGNOSIS SYSTEM
(a) Check the indicator.
When the ignition switch is turned ON, check that the ABS
warning light goes on for 3 seconds.
HINT:
If the indicator check result is not normal, proceed to trouble-
shooting for the ABS warning light circuit (See page DI−275).
(b) Check the DTC.
(1) Turn the ignition switch ON.
(2) Disconnect the short pin from the DLC1.
(3) Using SST, connect terminals Tc and E1 of the
DLC1.
SST 09843−18020
(4) Read the DTC from the ABS warning light on the
combination meter.
HINT:
If no code appears, inspect the diagnostic circuit or ABS
warning light circuit (See page DI−278 or DI−275).
As an example, the blinking patterns for normal code and
codes 11 and 21 are shown in the illustration.
(5) Codes are explained in the code table on page
DI−242.
(6) After completing the check, disconnect terminals Tc
and E1, and turn off the display.
If 2 or more malfunctions are indicated at the same time, the
lowest numbered DTC will be displayed 1st.

(c) Clear the DTC.
(1) Using SST, connect terminals Tc and E1 of the
DLC1.
SST 09843−18020
(2) Disconnect the short pin from the DLC1.
(3) Turn the ignition switch ON.
(4) Clear the DTC stored in ECU by depressing the
brake pedal 8 or more times within 3 seconds (4WD
models) or 5 seconds (2WD models).
(5) Check that the warning light shows the normal
code.
(6) Remove the SST from the terminals of the DLC1.
SST 09843−18020
(7) Connect the short pin to the DLC1.
HINT:
4WD vehicles:
Cancellation can also be done by removing the ECU−B fuse,
but in this case, other memory systems will also canlelled out.
(d) Using TOYOTA break−out−box and TOYOTA hand−held
tester, measure the ECU terminal values.
(1) Turn the ignition switch OFF.
(2) Hook up the TOYOTA hand−held tester and TOYO-
TA break−out−box to the vehicle.
(3) Turn the ignition switch ON.
(4) Read the ECU input / output values by following the
prompts on the tester screen.
HINT:
TOYOTA hand−held tester has a ”Snapshot” function. This re-
cords the measured values and is effective in the diagnosis of
intermittent problems. Please refer to the TOYOTA hand−held
tester / TOYOTA break−out−box operators manual for further
details.

2. SPEED SENSOR SIGNAL CHECK
(a) Check the speed sensor signal.
(1) Turn the ignition switch OFF.
(2) Using SST, connect terminals Ts and E1 of the
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−275).
(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 E1 of the
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 terminals Ts and
E1, and Tc and E1 of the DLC1, and turn the ignition
switch OFF.

3. DECELERATION SENSOR OPERATION DIAGNOSIS
SYSTEM
CAUTION:
While checking the deceleration sensor operating diagno-
sis system, the Anti−lock Brake System does not work and
brake system works as a conventional brake system.
Check the deceleration sensor output.
(1) Connect 3 dry batteries of 1.5 V in series.
(2) Connect VGS terminal to the batteries’ positive (+)
terminal, and GGND terminal to the batteries’ nega-
tive (−) terminal, apply about 4.5 V between VGS−
GGND terminals.
NOTICE:
Do not apply voltage of 6 V or more to terminals VGS and
GGND.
(3) Check the output of GL1 and GL2 terminals.
SymbolsConditionStandard Value
GL1Horizontalabout 2.3 V
GL1Lean forward0 − about 2.3 V
GL1Lean rearwardabout 2.3 V − 4.5 V
GL2Horizontalabout 2.3 V
GL2Lean forwardabout 2.3 V − 4.5 V
GL2Lean rearward0 − about 2.3 V
HINT:
If the senor is tilted too much it may show the wrong value.
If dropped, the sensor should be replaced with a new one.
The sensor removed from the vehicle should not be
placed upside down.

DIAGNOSTIC TROUBLE CODE CHART
If a malfunction code is displayed during the DTC check, check the circuit listed for that code. For details
of each code, turn to the page referred to under the ”See page” for the respective ”DTC No.” in the DTC chart.
HINT:
Using SST 09843−18020, connect the terminals Tc and E1, and remove the short pin.
If any abnormality is not found when inspect each inspection parts, inspect the ECU.
DTC No.
