(10) After checking the DTC, inspect the applicable cir-
cuit.
(b) Clear the DTC.
The following actions will erase the DTC and freezed
frame data.
(1) Operating the OBDII scan tool (complying with SAE
J1978) or TOYOTA hand−held tester to erase the
codes.
(See the OBDII scan tool’s instruction book for oper-
ating instructions.)
(2) Disconnecting the battery terminals or EFI fuse.
NOTICE:
If the TOYOTA hand−held tester switches the ECM from
normal mode to check mode or vice−versa, or it the ignition
switch is turned from ON to ACC or OFF during check
mode, the DTC and freezed frame data will be erased.
4. FAIL−SAFE CHART
If any of the following codes is recorded, the ECM enters fail−sate mode.
DTC No.Fail−Safe OperationFail−Safe Deactivation Conditions
P0105Ignition timing fixed at 5° BTDCReturned to normal condition
P0110Intake air temp. is fixed at 68°F (20°C)Returned to normal condition
P0115Engine coolant temp. is fixed at 176°F (80°C)Returned to normal condition
P0120VTA is fixed at 0°
The following condition must be repeated at least
2 times consecutively
When closed throttle position switch is ON:
0.1 V  VTA  0.95 V
P0325Max. timing retardationIgnition switch OFF
P1300Fuel cutIGF signal is detected for 1 ignition
5. CHECK FOR INTERMITTENT PROBLEMS
TOYOTA hand−held tester only:
By putting the vehicle’s ECM in check mode, 1 trip detection logic possible instead of 2 trip detection logic
and sensitivity to detect open circuit is increased. This makes it easier to detect intermittent problems.
(1) Clear the diagnostic trouble codes (See page DI−3)
(2) Set the check mode (See page DI−3)
(3) Perform a simulation test (See page IN−20)
(4) Check the connector and terminal inspection (See page IN−30)
(5) Visual check and contact pressure (See page IN−30)
(6) Handle the connector (See page IN−30)

INSPECTION PROCEDURE
1 Check voltage between terminals +B and E1 of ECM connector.
PREPARATION:
(a) Remove side trim cover (See page SF−61).
(b) Turn ignition switch ON.
CHECK:
Measure voltage between terminals +B and E1 of ECM connec-
tor.
OK:
Voltage: 9 − 14 V
OK Proceed to next circuit inspection shown on
matrix chart (See page DI−20).

2 Check for open in harness and connector between terminal E1 of ECM and body
ground (See page IN−30).
NG Repair or replace harness or connector.
OK
3 Check EFI main relay (Making: EFI) (See page SF−39).
NG Replace EFI main relay (Making: EFI)
OK
4 Check EFI fuse (See page DI−11 0, step 2).
NG Check for short in all the harness and compo-
nents connected of EFI fuse.
OK

HINT:
When 2 or more codes are indicated, the lowest numbered code will be displayed first.
If the inspection ”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 check.
If the trouble still reappears even though there are no abnormalities in any of the other circuits, then
check or replace the cruise control ECU as the last step.
(*) When the vehicle speed decrease on uphill roads, the speed can be set again and driving continued. (This
is not a malfunction.)

H POWER SOURCE (Current Flow Chart)
The chart below shows the route by which current flows from the battery to each electrical source (Fusible Link, Circuit
Breaker, Fuse, etc.) and other parts.
The next page and following pages show the parts to which each electrical source outputs current.

B HOW TO USE THIS MANUAL
The Current Flow Chartº section, describes which parts each power source (fuses, fusible links, and circuit breakers)
transmits current to. In the Power Source circuit diagram, the conditions when battery power is supplied to each system are
explained. Since all System Circuit diagrams start from the power source, the power source system must be fully understood.
