DIAGNOSTIC TROUBLE CODE CHART
HINT:

Using SST 09843±18040, connect the terminal Tc and CG of the DLC3.

If malfunction is not found when inspecting parts, inspect the ECU and grou\
nd points for poor contact.

If a malfunction code is displayed during the DTC check, check the circuit\
listed for that code. For de-
tails of each code, refer to the ºSee pageº for respective ºDTC No.º\
in the DTC chart.

When 2 or more DTCs are detected, perform circuit inspection one by one unti\
l the problem is identi-
fied.

AVENSIS RE PAIR MANUAL (RM1018E)
PRE±CHECK
1. DIAGNOSI S SYSTEM
(a ) Release the parking brake leve r.
(b ) Check the warning lights.
Whe n the ignition switch is turned ON, check that the ABS
warnin g light and brake warning light come on for 3 sec.
HIN T:

Whe n the parking brake is applied or the level of the brake
flui d is lo w, the brake warning light comes on.

If the indicator check result is not normal, proceed to trou-
bleshootin g for the ABS warning light circuit ( See page
05±73 7 or 05±741 ) or brake warning light circuit ( See
pag e 05±744 ).
(c ) Without using hand±held tester:
Check the DTC.
(1 ) Usin g S S T, c onne ct te rmi na l T c a n d C G o f the
DLC3.
SS T 09843±18040
(2 ) Tur n the ignition switch ON.
(3 ) Rea d the DTC from the ABS warning light on the
combinatio n mete r.
HIN T:

If no code appears, inspect the diagnostic circuit or ABS
warning light circuit ( See page 05±737 or 05±744 ).

As an example, the blinking patterns for normal code and
code s 1 1 and 21 are shown on the left.
(4 ) Codes are explained in the code table on page
05±704.
If 2 or more DTCs are detected at the same time, the lowest
numbered DTC is displayed 1st. (5) After completing the check, remove the SST fromthe DLC3.
SST 09843±18040
(d) With using hand±held tester: Check the DTC.
(1) Read the DTC by following the prompts on the tes-ter screen.
HINT:
Please refer to the hand±held tester operator's manual for fur-
ther details.
(e) Without using hand±held tester: Clear the DTCs.
(1) Using SST, connect the terminal Tc and CG of theDLC3.

(3) Clear the DTCs stored in ECU by depressing the
brake pedal 8 or more times within 5 sec.
(4) Check that the ABS warning light indicates the nor-
mal code blinking pattern.
(5) Remove the SST from the DLC3.
SST 09843±18040
HINT:
Disconnecting the battery cable during repairs will not erase the
DTCs in the ECU.
(f) With using hand±held tester:
Clear the DTCs.
(1) Turn the ignition switch ON.
(2) Operate the hand±held tester to erase the codes.
HINT:
Please refer to the hand±held tester operator's manual for fur-
ther details.
2. DATA LIST
HINT:
According to the DATA LIST displayed on the Hand±held tester, you can read the value and status of the
switch, sensor, actuator and so on without parts removal. Reading the DATA LIST as a first step of trouble-
shooting is one of the methods to shorten the labor time.
(a) Connect the Hand±held tester to the DLC3.
(b) Turn the ignition switch ON.
(c) From the display on the tester, read the ºDATA LISTº.
