Code No.C1382: Abnormal voltage (low voltage) of G-sensor <4WD>
Code No.C1383: Abnormal voltage (high voltage) of G-sensor <4WD>



caution If there is any problem in the CAN bus lines, an incorrect diagnosis code may be set. Diagnose the CAN bus lines before the diagnosis codes (Refer to GROUP 54C, CAN bus-line diagnostic flow ).

OPERATION




DIAGNOSIS CODE SET CONDITIONS




  • With diagnosis codes No. C1365, C1382, and C1383 being not set, the input value of the G-sensor does not change.
  • With diagnosis codes No. C1365, C1382, and C1383 being not set, the acceleration calculated from the G-sensor and the acceleration calculated from the vehicle speed are not equal.

PROBABLE CAUSES




  • Damaged wiring harness or connector
  • Malfunction of the G-sensor
  • Malfunction of the hydraulic unit assembly (integrated with ABS-ECU)

DIAGNOSIS


STEP 1. M.U.T.-III CAN bus diagnostics.




caution Before connecting or disconnecting the M.U.T.-III, turn the ignition switch to the "LOCK" (OFF) position.
(1)Connect M.U.T.-III to the 16-pin diagnosis connector.
(2)Turn the ignition switch to the "ON" position.
(3)Diagnose the CAN bus line.
(4)Turn the ignition switch to the "LOCK" (OFF) position.

Q. Is the check result normal?

Go to Step 3.

Repair the CAN bus line (Refer to GROUP 54C, CAN bus line Diagnostic flow ). Then go to Step 2.

STEP 2. Check whether the diagnosis code is reset.




caution Before connecting or disconnecting the M.U.T.-III, turn the ignition switch to the "LOCK" (OFF) position.
(1)Turn the ignition switch to the "ON" position.
(2)Erase the diagnosis code.
(3)Turn the ignition switch to the "LOCK" (OFF) position.
(4)Turn the ignition switch to the "ON" position.
(5)Check if the diagnosis code is set.
(6)Turn the ignition switch to the "LOCK" (OFF) position.

Q. Is code No.C1381 set?

Go to Step 3.

The procedure is complete.

STEP 3. Check the G-sensor.


Refer to .

Q. Is the check result normal?

Go to Step 4.
Replace the G-sensor. Then go to Step 5.

STEP 4. Check whether the diagnosis code is reset.




Check again if the diagnosis code is set.
(1)Turn the ignition switch to the "ON" position.
(2)Erase the diagnosis code.
(3)Turn the ignition switch to the "LOCK" (OFF) position.
(4)Turn the ignition switch to the "ON" position.
(5)Check if the diagnosis code is set.
(6)Turn the ignition switch to the "LOCK" (OFF) position.

Q. Is code No.C1381 set?

Replace the hydraulic unit assembly (integrated with ABS-ECU). Then go to Step 5.

It can be assumed that this malfunction is intermittent. Refer to GROUP 00, How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunction .

STEP 5. Check whether the diagnosis code is reset.




Check again if the diagnosis code is set.
(1)Turn the ignition switch to the "ON" position.
(2)Erase the diagnosis code.
(3)Turn the ignition switch to the "LOCK" (OFF) position.
(4)Turn the ignition switch to the "ON" position.
(5)Check if the diagnosis code is set.
(6)Turn the ignition switch to the "LOCK" (OFF) position.

Q. Is code No.C1381 set?

Go to Step 1.

The procedure is complete.
