Code No. P0763: 3-5 Reverse Clutch Linear Solenoid Valve System


DIAGNOSIS CODE SET CONDITIONS


During the 1st, 2nd, 4th, and 6th gear driving, an abnormal value equivalent to open or short circuit is detected in the solenoid control current for 5 seconds.

PROBABLE CAUSES



DIAGNOSIS PROCEDURE

STEP 1. Check the A/T-ECU terminal voltage.
[A/T-ECU connector (harness side, connected)]
Measure the voltage between 35LS terminal and body earth.

  • When 3-5 reverse clutch engaged. (3rd, 5th, and reverse): 0 V
  • Other than above: 300 Hz

Q. Is the check result normal?
Go to Step 5.
Go to Step 2.

STEP 2. Check for continuity in 35LS line between the A/T-ECU connector and A/T control solenoid valve assembly connector.
When the continuity check result is OK, check that the wiring harness is not shorted to the body and other wiring harness.

Q. Is the check result normal?
Go to Step 3.
Repair the connector(s) or wiring harness.

STEP 3. Check the 3-5 reverse clutch linear solenoid.
Refer to .

Q. Is the check result normal?
Go to Step 6.
Go to Step 4.

STEP 4. Check for continuity in signal line between the A/T control solenoid valve assembly connector and the 3-5 reverse clutch linear solenoid valve connector.

Q. Is the check result satisfactory?
Replace the valve body assembly.
Repair the connector(s) or wiring harness.

STEP 5. Check the A/T-ECU and A/T control solenoid valve assembly connector pin terminals and the connection status.

Q. Is the check result normal?
Go to Step 7.
Repair or replace the failure section.

STEP 6. Check the A/T-ECU and A/T control solenoid valve assembly connector pin terminals and the connection status.

Q. Is the check result normal?
Replace the A/T-ECU.
Repair or replace the failure section.

STEP 7. Erase the diagnosis code, and drive the vehicle for a while.
Check that the normal code is displayed.

Q. Is the check result normal?
The procedure is complete.
Return to Step 1.
