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
troubleshooting for the ABS warning light circuit
(See page DI±529).
(b) Check the DTC.
(1) Disconnect the short pin from DLC1.
(2) Using SST, connect terminals Tc and E
1 of DLC2 or
DLC1.
SST 09843 ± 18020
(3) Turn the ignition switch ON.
(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±532 or DI±529).
As an example, the blinking patterns for normal code and
codes 11 and 21 are shown on the left.
(5) Codes are explained in the code table on page
DI±497.
(6) After completing the check, disconnect terminals Tc
and E
1, and turn off the display.
If 2 or more malfunctions are indicated at the same time the low-
est numbered DTC will be displayed 1st.

1. DIAGNOSIS SYSTEM
(a) Check the indicator.
When the ignition switch is turned ON, check that the ABS
warning light, TRAC OFF indicator light and SLIP indica-
tor light go on for 3 seconds.
HINT:

shooting for the ABS warning light circuit, TRAC OFF indicator
light circuit and SLIP indicator light circuit
(See page DI±612, DI±617, DI±620).
(b) Check the DTC.
(1) Using SST, connect terminals Tc and E

(2) Turn the ignition switch ON.
(3) Read the DTC from the ABS warning light and

ing light circuit, TRAC OFF indicator light circuit
(See page DI±621 or DI±612, DI±617).
As an example, the blinking patterns for normal code and codes
11 and 21 are shown on the left.

1. SRS WARNING LIGHT CHECK
(a) Turn the ignition switch to the ACC or ON position and
check that the SRS warning light lights up.
(b) Check that the SRS warning light goes out after approx.
6 seconds.
HINT:
When the ignition switch is at ACC or ON and the SRS
warning light remains on or flashes, the airbag sensor as-
sembly has detected a malfunction code.
If, after approx. 6 seconds have elapsed, the SRS warn-
ing light sometimes lights up or the SRS warning light
lights up even when the ignition switch is OFF, a short in
the SRS warning light circuit can be considered likely.
Proceed to ºSRS warning light circuit malfunctionº on
page DI±790, DI±792.
2. DTC CHECK (Using diagnosis check wire)
(a) Present troubles codes:
Output the DTC.
(1) Turn the ignition switch to the ACC or ON position
and wait for approx. 20 seconds.
(2) Using SST, connect terminals Tc and E1 of the
DLC1.
SST 09843±18020
NOTICE:
Pay due attention to the terminal connecting position to
avoid a malfunction.
(b) Past troubles codes:
Output the DTC.
(1) Using service wire, connect Terminals Tc and E1 of
the DLC1.
SST 09843±18020
(2) Turn the ignition switch to the ACC or ON position
and wait for approx. 20 seconds.
NOTICE:
Pay due attention to the terminal connecting position to

(c) Read the DTC.
Read the 2±digit DTC as indicated by the number of times
the SRS warning light blinks. As an example, the blinking
patterns, normal, 11 and 31 are shown in the illustration.
Normal code indication
The light will blink 2 times per second.
Malfunction code indication
The first blinking output indicates the first digit
of a 2±digit DTC. After a 1.5±second pause,
the second blinking output will indicate the
second digit.
If there are 2 or more codes, there will be a 2.5±second pause
between each code. After all the codes have been output, there
will be a 4.0±second pause and they will all be repeated.
HINT:
In the event of a number of trouble codes, indication will
start from the smallest numbered code.
If a DTC is not output or a DTC is output without terminal
connection, proceed to the Tc terminal circuit inspection
on page DI±796.
3. DTC CHECK (Using TOYOTA hand±held tester)
(a) Hook up the TOYOTA hand±held tester to the DLC1 or
the DLC3.
(b) Read the DTCs by following the prompts on the tester
screen.
HINT:
Please refer to the TOYOTA hand±held tester operator's manu-
al for further details.
4. DTC CLEARANCE (Not using service wire)
When the ignition switch is turned off, the diagnostic trouble
code is cleared.
HINT:
DTC might not be cleared by turning the ignition switch OFF.
In this case, proceed to the next step.
5. DTC CLEARANCE (Using service wire)
(a) Connect the 2 service wires to terminals Tc and AB of
DLC1.
(b) Turn the ignition switch to ACC or ON and wait for approx.
6 seconds.

(c) Starting with the Tc terminal, ground alternately terminal
Tc and terminal AB twice each in cycles of 1.0 seconds.
Make sure that the terminals are grounded. Ensure the
terminal Tc remain grounded.
HINT:
When alternately grounding terminals Tc and AB, release
ground from one terminal and immediately ground the other ter-
minal within an interval of 0.2 seconds.
If DTCs are not cleared, repeat the above procedure until the
codes are cleared.
(d) Several seconds after doing the clearing procedure, the
SRS warning light will blink in a 50 m sec. cycle to indicate
the codes which have been cleared.

HINT:
When the SRS warning light remains lit up and the DTC is the normal code, this means a voltage source
drops.
This malfunction is not stored in memory by the airbag sensor assembly and if the power source volt-
age returns to normal, the SRS warning light will automatically go out.
When 2 or more codes are indicated, the codes will be displayed in numeral order starting from the
lowest numbered code.
If a code not listed on the chart is displayed, the airbag sensor assembly is faulty.
