DTC CONFIRMATION PROCEDURE

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.

CHECK DTC DETECTION

1. Start the engine and wait for 5 seconds or more

2. Check the first trip DTC.
Is “P099C” detected?

YES

>> Go to

TM-216, "Diagnosis Procedure"

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000009759466

CHECK CIRCUIT BETWEEN TCM AND CVT UNIT

1. Turn ignition switch OFF.

2. Disconnect TCM connector and CVT unit connector.

3. Check continuity between TCM harness connector terminal and CVT unit harness connector terminal.

Is the inspection result normal?

YES

>> GO TO 2.

>> Repair or replace malfunctioning parts.

CHECK HIGH CLUTCH & REVERSE BRAKE SOLENOID VALVE

Check high clutch & reverse brake solenoid valve. Refer to

TM-216, "Component Inspection"

Is the inspection result normal?

YES >> Check

intermittent incident. Refer to

GI-39, "Intermittent Incident"

>> Repair or replace malfunctioning parts.

NOTE:

DC stands for “DRIVING CYCLE” and indicates a series of driving cycle of “Ignition switch OFF

→ ON → driv-

ing

→ OFF”.

DTC CONFIRMATION PROCEDURE

CAUTION:

Be careful of the driving speed.

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.

CHECK DTC DETECTION

With CONSULT

1. Start the engine.

2. Drive the vehicle for 10 seconds or more.

3. Stop the vehicle.

CAUTION:

Never stop the engine.

4. Repeat step 2 through 3.

5. Check the DTC.
Is “P1586” detected?

YES

>> Go to

TM-218, "Diagnosis Procedure"

Diagnosis Procedure

INFOID:0000000009759469

CHECK G SENSOR SIGNAL

With CONSULT

1. Park the vehicle on a level surface.

2. Turn ignition switch ON.

DTC detection condition

Possible causes

P1586

G Sensor
(Gravity Sensor Circuit)

When the following diagnosis conditions are
satisfied and the detection conditions are sat-
isfied twice in the same DC:
• Diagnosis conditions
- While driving
- TCM power supply voltage: More than 11 V
• Detection condition
- The G sensor detection voltage is 0.7 V or

less continuously for 5 seconds or more.

• Harness or connector

(G sensor circuit)

• G sensor

more continuously for 5 seconds or more.

3. Select “Data Monitor” in “TRANSMISSION”.

4. Select “G SEN SLOPE”.

5. Swing the vehicle and check if the value varies between

−40.45% and 40.45%.

Is the inspection result normal?

YES

>> GO TO 2.

>> GO TO 3.

CALIBRATION OF G SENSOR (PART 1)

With CONSULT

1. Select “Self Diagnostic Results” in “TRANSMISSION”.

2. Touch “Erase”.

>> Perform “CALIBRATION OF G SENSOR”. Refer to
