DTC detection condition

Possible causes
P1588 G Sensor (Gravity Sensor Circuit) When the following diagnosis conditions are satisfied and the detection conditions are satisfied twice in the same DC:

Diagnosis condition (1 second or more)

  • The rate of change in G sensor detection value (mV): Between −15 and +15 inclusive

Detection condition

  • The rate of change in acceleration/deceleration stays 0.2677 m/s2 (0.0273 G) or more/ −0.2677 m/s2 (−0.0273 G) or less at least for 5 seconds or more.
 G sensor

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


  1. Start the engine.
  2. Select “Data Monitor” in “TRANSMISSION”.
  3. Select “G SPEED”.
  4. Drive the vehicle.
  5. Maintain the following conditions for 8 seconds or more.

Selector lever : “D” position

G SPEED : 0.05 G or more

  1. Stop the vehicle

CAUTION:

Never stop the engine.

  1. Repeat steps 4 through 6.
  2. Check the DTC.

Is “P1588” detected? YES >> Go to TM-221, "Diagnosis Procedure".

NO >> INSPECTION END

Diagnosis Procedure

1.CHECK G SENSOR SIGNAL

With CONSULT


  1. Park the vehicle on a level surface.
  2. Turn ignition switch ON.
  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?


Is the inspection result normal? YES >> GO TO 2.

NO >> GO TO 3.

2.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 TM-147, "Work Procedure".

3.Check g sensor

  1. Remove G sensor. Refer to TM-265, "Removal and Installation".
  2. Connect the all connectors.
  3. Turn ignition switch ON
  4. Check voltage between TCM connector terminal and ground.
