NOTE:
DC stands for “DRIVING CYCLE” and indicates a series of driving cycle of “Ignition switch OFF → ON → driving → OFF”.
DTC CONFIRMATION PROCEDURE
CAUTION:
Be careful of the driving speed.
1.PREPARATION BEFORE WORK
If another “DTC CONFIRMATION PROCEDURE” occurs just before, turn ignition switch OFF and wait for at least 10 seconds, then perform the next test.
>> GO TO 2.
2.CHECK DTC DETECTION
With CONSULT
CAUTION:
Never stop the engine.
Is “P1586” detected? YES >> Go to TM-218, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis Procedure
1.CHECK G SENSOR SIGNAL
With CONSULT
Is the inspection result normal? YES >> GO TO 2.
NO >> GO TO 3.
2.CALIBRATION OF G SENSOR (PART 1)
With CONSULT
>> Perform “CALIBRATION OF G SENSOR”. Refer to TM-147, "Work Procedure".
3.CHECK SENSOR POWER SUPPLY
Is the inspection result normal? YES >> GO TO 4.
NO >> GO TO 8.
4.CHECK CIRCUIT BETWEEN TCM AND G SENSOR (PART 1)
Is the inspection result normal? YES >> GO TO 5.
NO >> Repair or replace malfunctioning parts.
5.CHECK CIRCUIT BETWEEN TCM AND G SENSOR (PART 2)
Check continuity between TCM harness connector terminal and ground.
The inspection result normal? Yes >> go to 6.
No >> repair or replace malfunctioning parts.
6.Check g sensor
: Direction of gravitational
force
Is the inspection result normal? Yes >> go to 7.
No >> replace g sensor. Refer to tm-265, "removal and installation".
7.Calibration of g sensor (part 2)
With CONSULT
>> Perform “CALIBRATION OF G SENSOR”. Refer to TM-147, "Work Procedure".
8.CHECK SENSOR POWER SUPPLY CIRCUIT (PART 1)
Is the inspection result normal? YES >> GO TO 9.
NO >> Repair or replace malfunctioning parts.
9.CHECK SENSOR POWER SUPPLY CIRCUIT (PART 2)
Check continuity between TCM harness connector terminal and ground.
Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-39, "Intermittent Incident".
NO >> Repair or replace malfunctioning parts.
If you think something
is wrong
If you notice any of the following symptoms, your vehicle probably
needs adjustment or repair. Contact your Toyota dealer as
soon as possible.

Brake precautions
Vacuum assisted brakes
The brake booster aids braking by using engine
vacuum. If the engine stops, you can stop the
vehicle by depressing the brake pedal. However,
greater foot pressure on the brake pedal will be
required to stop the vehicle and stopping distance
will be longer.
