HINT:
If your display shows ”UNABLE TO CONNECT TO VEHICLE”
when you have connected the cable of the OBDII scan tool or
TOYOTA hand−held tester to DLC3, turned the ignition switch
ON and operated the scan tool, there is a problem on the ve-
hicle side or tool side.
If communication is normal when the tool is connected to
another vehicle, inspect 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.
(2) When the engine is started, the MIL should go off.
If the lamp remains on,the diagnosis system has
detected a malfunction or abnormality in the sys-
tem.
(b) Check the DTC.
NOTICE:
TOYOTA hand−held tester only:
When the diagnosis system is switched from normal mode
to check mode, it erases all DTC and freezed frame data re-
corded in normal mode. So before switching modes, al-
ways check the DTC and freezed frame data, and note them
down.
(1) Prepare the OBDII scan tool (complying with SAE
J1978) or TOYOTA hand−held tester.
(2) Connect the OBDII scan tool or TOYOTA hand−
held tester to DLC3 at the lower of the instrument
panel.
(3) Turn the ignition switch ON and turn the OBDII scan
tool or TOYOTA hand−held tester switch ON.
(4) Use the OBDII scan tool or TOYOTA hand−held tes-
ter to check the DTC and freezed frame data, note
them down.
(5) See page DI−14 to confirm the details of the
DTC.

(f) Check the fluid leaks.
Check for leaks in the transmission and transfer.
If there are leaks, it is necessary to repair or replace O − rings,
FIPG’s, oil seals or other parts.
(g) Inspect and adjust the throttle cable.
(1) Check that the throttle valve is fully closed.
(2) Check that the inner cable is not slack.
(3) Loosen the adjustment nuts.
(4) Adjust the outer cable so that the distance between
the end of the boot and stopper on the cable is as
standard.
Standard boot and cable stopper distance:
0 − 1 mm (0 − 0.04 in.)
(5) Tighten the adjusting nuts.
(6) Recheck the adjustments.
(h) Adjust the shift control cable.
(1) Loosen the nut on the lever.
(2) Push the manual lever fully toward the right side of
the vehicle.

PROBLEM SYMPTOMS TABLE
If a normal code is displayed during the DTC check but the trouble still occurs (reappears), troubleshoot for
each problem symptom, checking the circuits for each symptom in the order given in the table below. Pro-
ceed to the page indicated for each circuit.
HINT:
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.
If the trouble still reappears even through there are no abnormalities in any of the other circuits, then
check or replace the cruise control ECU as the last step.
