PROBLEM SYMPTOMS TABLE
If a normal code is displayed during the diagnostic trouble code check but the trouble still occurs, check the
circuits for each symptom in the order given in the charts on the following pages and proceed to the page
given for troubleshooting.
The Matrix Chart is divided into 3 chapters.
Chapter 1: Electronic Circuit Matrix Chart
Chapter 2: On−Vehicle Repair Matrix Chart
Chapter 3: Off−Vehicle Repair Matrix Chart
When troubleshooting, check Chapter 1 first. If instructions are given in Chapter 1 to proceed to chapter 2
or 3, proceed as instructed.
(1) If the instruction ”Proceed to next circuit inspection shown on matrix chart” is given in the flow
chart for each circuit, proceed to the circuit with the next highest number in the table to continue
the check.
(2) If the trouble still occurs even though there are no abnormalities in any of the other circuits, then
check and replace the ECM.

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.

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.

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.

1 Check voltage between terminals Tc and E1 of DLC1.
CHECK:
(a) Turn the ignition switch ON.
(b) Measure the voltage between terminals Tc and E1 of the
DLC1.
OK:
Voltage: 10 − 14 V
OK If ABS warning light does not blink even after Tc
and E1 are connected, ECU may be defective.

2. ECU TERMINAL VALUES MEASUREMENT USING
TOYOTA BRAKE−OUT−BOX AND TOYOTA HAND−
HELD TESTER
(a) Hook up the TOYOTA break−out−box and TOYOTA
hand−held tester to the vehicle.
(b) Read the ECU input/output values by following the
prompts on the scan tool screen.
HINT:
TOYOTA hand−held tester has a ”Snapshot” function.
This records the measured values and is effective in the diagno-
sis of intermittent problems.
Please refer to the TOYOTA hand−held tester/TOYOTA break−
out−box operator’s manual for further details.
