PRE-CHECK
1. DIAGNOSIS SYSTEM
(a) Check the indicator.
(1) Turn the ignition switch ON.
(2) Check that the CRUISE MAIN indicator light comes
ON when the cruise control main switch is turned
ON, and that the indicator light goes OFF when the
main switch is turned OFF.
HINT:
If the indicator check result is not normal, proceed to trouble-
shooting (See page BE-43) for the combination meter
section.
(b) Check the DTC.
HINT:
If a malfunction occurs in the No. 1 vehicle speed sensor or ac-
tuator, etc. during cruise control driving, the ECU actuates
AUTO CANCEL of the cruise control and turns on and off the
CRUISE MAIN indicator light to inform the driver of a malfunc-
tion. At the same time, the malfunction is stored in memory as
a DTC.
(c) Output of DTC using diagnosis check wire.
(1) Turn the ignition switch ON.
(2) Using SST, connect terminals Tc and E
1 of DLC2.
SST 09843-18020
(3) Read the DTC on the CRUISE MAIN indicator light.

DTC P0500 Vehicle Speed Sensor Malfunction
CIRCUIT DESCRIPTION
This sensor is mounted in the combination meter. It contains a magnet which is rotated by the speedometer
cable.
Turning the reed switch ON and OFF 4 times for every revolution of the speedometer.
It is then transmitted to the Engine ECM. The Engine ECM determines the vehicle speed based on the fre-
quency of these pulse signals.

INSPECTION PROCEDURE
HINT:
Read freeze frame data using TOYOTA hand-held tester or OBD II scan tool. Because freeze frame records
the engine conditions when the malfunction is detected. When troubleshooting, it is useful for determining
whether the vehicle was running or stopped, the engine was warmed up or not, the air-fuel ratio was lean
or rich, etc. at the time of the malfunction.

(b) Check the DLC3.
The vehicle's ECM uses ISO 9141-2 for communication.
The terminal arrangement of DLC3 complies with SAE
J1962 and matches the ISO 9141-2 format.

HINT:
If your display shows UNABLE TO CONNECT TO VEHICLE
when you have connected the cable of the OBD II scan tool or
TOYOTA hand-held tester to the DLC3, turned the ignition
switch ON and operated the scan tool, there is a problem 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. INSPECT DIAGNOSIS (Normal Mode)
(a) Check the MIL.
(1) The MIL comes on when the ignition switch is turned
ON and the engine is not running.
HINT:
If the MIL does not light up, troubleshoot the combination meter
(See page BE-53).
(2) When the engine started, the MIL should go off. If
the lamp remains on, the diagnosis system has de-
tected a malfunction or abnormality in the system.
(b) Check the DTC.
NOTICE:
If there is no DTC in the normal mode, check the 1st
trip DTC using Continuous Test Results function
(Mode 7 for SAE J1979) or the OBD II scan tool or TOY-
OTA hand-held tester.

SRS Warning Light Circuit Malfunction
CIRCUIT DESCRIPTION
The SRS warning light is located on the combination meter.
When the SRS is normal, the SRS warning light lights up for approx. 6 seconds after the ignition switch is
turned from the LOCK position to ACC or ON position, and then turns off automatically.
If there is a malfunction in the SRS, the SRS warning light lights up to inform the driver of the abnormality.
When terminals Tc and E1 of the DLC1 are connected, the DTC is displayed by blinking the SRS warning
light.

CIRCUIT INSPECTION
Indicator Light Circuit
CIRCUIT DESCRIPTION
When the theft deterrent system is preparing to set, this circuit lights up the indicator light. When the system
has been set, it continuously turns the indicator light on for 0.75 secs. and turns it off for 1.25 secs., thus
blinking the indicator light.

INSPECTION PROCEDURE
1 Check indicator light.
PREPARATION:
Remove combination meter.
CHECK:
Connect the positive (+) lead from the battery to terminal B22 and the negative (-) lead to terminal B21 of
combination meter connector then check indicator light comes ON.
(See combination meter on page BE-43)
NG Replace combination meter.

(3) Even in cases of a minor collision where the SRS
does not deploy, the steering wheel pad, front pas-
senger airbag assembly, side airbag assembly and
seat belt pretensioner should be inspected (See
page RS- 15, RS- 30, RS- 44, RS- 57 and
BO-130).
(4) Never use SRS parts from another vehicle. When
replacing parts, replace them with new parts.
(5) Before repairs, remove the airbag sensor if shocks
are likely to be applied to the sensor during repairs.
(6) Never disassemble and repair the airbag sensor as-
sembly, steering wheel pad, front passenger airbag
assembly, side airbag assembly or seat belt preten-
sioner.
(7) If the airbag sensor assembly, steering wheel pad,
front passenger airbag assembly, side airbag as-
sembly or seat belt pretensioner has been dropped,
or if there are cracks, dents or other defects in the
case, bracket or connector, replace them with new
ones.
(8) Do not directly expose the airbag sensor assembly,
steering wheel pad, front passenger airbag assem-
bly, side airbag assembly or seat belt pretensioner
to hot air or flames.
(9) Use a volt/ohmmeter with high impedance (10 kW/V
minimum) for troubleshooting of the electrical cir-
cuit.
(10) Information labels are attached to the periphery of
the SRS components. Follow the instructions on the
notices.
(11) After work on the supplemental restraint system is
completed, check the SRS warning light (See page
DI-349).
(c) SPIRAL CABLE (in Combination Switch)
The steering wheel must be fitted correctly to the steering
column with the spiral cable at the neutral position, other-
wise cable disconnection and other troubles may result.
Refer to SR-22 of this manual concerning correct steer-
ing wheel installation.
