(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 ).

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

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.

ther details.
(e) Without using hand±held tester: Clear the DTCs.

1.DIAGNOSIS SYSTEM
(a)Check the warning lights. (1)Release the parking brake lever.
(2)When the ignition switch is turned ON, check thatthe ABS warning light, Brake warning light, VSC
warning light, TRC OFF indicator light and SLIP in-
dicator light come on for approx. 3 seconds.
HINT:
When the parking brake is applied or brake fluid level is
low, the Brake warning light comes on.
If the ECU stores DTC, the ABS warning light , VSC warn-
ing light and TRC OFF indicator light come on.
If the indicator check result is not normal, proceed to trou-
bleshooting for the light circuit.

AVENSIS REPAIR MANUAL (RM1018E)
PRE±CHECK
1.DIAGNOSIS SYSTEM
(a)Check the DLC3. (1)The vehicle's ECM conforms to ISO 9141±2 forcommunication protocol. The terminal arrangement
of the DLC3 complies with ISO 15031±3 and meets
the ISO 9141±2 format.
Terminal No.Connection/Voltage or ResistanceCondition
7Bus + Line/Pulse generationDuring Transmission
4Chassis Ground Body Ground/1 or lessAlways
16Battery Positive Body Ground/9 ± 14 VAlways
HINT:
If the display shows UNABLE TO CONNECT TO VEHICLE
when you connect the cable of the hand±held tester to the
DLC3, turn the ignition switch to the ON position and operate
the hand±held tester, there is a problem either on the vehicle
side or tool side.
If communication is normal when the tool is connected to
another vehicle, inspect the DLC3 on the original vehicle.
If communication is still not possible when the tool is con-
nected to another vehicle, the problem is probably in the
tool itself, so consult the Service Department listed in the
tool's instruction manual.
2.SRS WARNING LIGHT CHECK
(a)Turn the ignition switch to the ON position, and check that the SRS warning light comes on.
(b)Check that the SRS warning light goes off after approx.
6 seconds.
HINT:
When the ignition switch is ON position and the SRS
warning light remains on or flashes, the airbag sensor
assy center detects a malfunction code.
When the SRS warning light comes on even when the
ignition switch is in the LOCK position, trouble in the pow-
er source or combination meter assy is suspected. Pro-
ceed to ºSRS warning light circuit malfunction (Always
lights up, when ignition switch is LOCK position)º on page
05±1386.
When the ignition switch is turned from the LOCK to ON
position, the SRS warning light does not come on. Pro-
ceed to ºSRS warning light circuit malfunction (Does not
light up, when ignition switch is turned ON)º on page
05±1389.
