6. BASIC INSPECTION
When the malfunction code is not confirmed in the DTC check, troubleshooting should be performed in the
order for all possible circuits to be considered as the causes of the problems. In many cases, by carrying
out the basic engine check shown in the following flow chart, the location causing the problem can be found
quickly and efficiently. Therefore, use of this check is essential in engine troubleshooting.
1 Is battery positive voltage 11 V or more when engine is stopped?
NO Charge or replace battery.
YES
2 Is engine cranked?
NO Proceed to page ST−15 and continue to trouble-
shoot.
YES
3 Does engine start?
NO Go to step 7.
YES
4 Check air filter.
PREPARATION:
Remove the air filter.
CHECK:
Visual check that the air filter is not dirty or excessive oily.
HINT:
If necessary, clean the filter with compressed air. First blow from
inside thoroughly, then blow from outside of the filter.
NG Repair or replace.
OK

(b) Clear the DTC.
The following actions will erase the DTCs and freezed
frame data.
(1) Operating the OBD II scan tool (complying with SAE
J1978) or TOYOTA hand−held tester to erase the
codes (See the OBD II scan tool’s instruction book
for operating 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 if the igni-
tion switch is turned from ON to ACC or OFF during check
mode, the DTCs and freezed frame data will be erased.
4. FAIL−SAFE CHART
If any of the following codes is recorded, the ECM enters fail−safe mode.
DTC No.Fail−Safe OperationFail−Safe Deactivation Conditions
P0100Ignition timing fixed at 10° BTDCReturned to normal condition
P0110Intake air temp. is fixed at 20°C (68°F)Returned to normal condition
P0115Engine coolant temp. is fixed at 80°(176°F)Returned to normal condition
P0120VTA is fixed at 0°
Following condition must be repeated at least 2 times
consecutively

P1300Fuel cutIGF signal is detected for 6 consective ignitions
5. CHECK FOR INTERMITTENT PROBLEMS
HINT:
TOYOTA HAND−HELD TESTER only:
By putting the vehicle’s ECM in check mode, 1 trip detection logic is possible instead of 2 trip detection logic
and sensitivity to detect open circuits is increased. This makes it easier to detect intermittent problems.
(a) Clear the DTCs (See step 3).
(b) Set the check mode (See step 3).
(c) Perform a simulation test (See page IN−16).
(d) Check the connector and terminal (See page IN−26).
(e) Handle the connector (See page IN−26).

STARTER RELAY
INSPECTION
1. REMOVE STARTER RELAY (Marking: ”ST”)
LOCATION: The relay is located in the No.1 junction block on
the driver’s side.
2. INSPECT STARTER RELAY CONTINUITY
(a) Using an ohmmeter, check that there is continuity be-
tween terminals 1 and 2.
If there is no continuity, replace the relay.
(b) Check that there is no continuity between terminals 3 and
5.
If there is continuity, replace the relay.
3. INSPECT STARTER RELAY OPERATION
(a) Apply battery voltage across terminals 1 and 2.
(b) Using an ohmmeter, check that there is continuity be-
tween terminals 3 and 5.
If there is no continuity, replace the relay.
4. REINSTALL STARTER RELAY
