DTC P0963: A/T Clutch Pressure Control Solenoid Valve A

WARNING: This page is about a different car, the 2013 Honda Fit, 2012 Honda Fit, 2011 Honda Fit, 2010 Honda Fit, and 2009 Honda Fit. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

Before you troubleshoot, record all freeze data and any on-board snapshot with the HDS, and review General Troubleshooting Information (see GENERAL TROUBLESHOOTING INFORMATION ).
This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.

Clear the DTC with the HDS.
Check that DTC P0963 recurs.
Is DTC P0963 indicated?

YES -Go to step 6.

NO -Go to step 3.
Select Clutch Pressure Control (Linear) Solenoid Valve A in the Miscellaneous Test Menu, and test A/T clutch pressure control solenoid valve A with the HDS.
Does the HDS indicate NORMAL?

YES -Go to step 4.

NO - go to step 6.
In the Clutch Pressure Control Solenoid Control menu, select Clutch Pressure Control Solenoid Valve A at 0.2 A.
Monitor the OBD status for P0963 in the DTCs/Freeze Data in A/T Mode Menu for a pass/fail.
Does the HDS indicate FAILED?

YES -Go to step 6.

NO -Intermittent failure, the system is OK at this time. Check for poor connections and loose terminals at A/T clutch pressure control solenoid valve A and the PCM. If the HDS indicates NOT COMPLETED, return to step 3 and recheck.
Turn the ignition switch to LOCK (0).
Disconnect the A/T clutch pressure control solenoid valve A connector.
Measure the resistance between A/T clutch pressure control solenoid valve A connector terminals No. 1 and No. 2.

Is there 3-10 Ω?

YES -Go to step 9.

NO -Replace A/T clutch pressure control solenoid valve A (see A/T CLUTCH PRESSURE CONTROL SOLENOID VALVE A REPLACEMENT ), then go to step 15.
Check for continuity between A/T clutch pressure control solenoid valve A connector terminal No. 2 and body ground.

Is there continuity?

YES -Go to step 10.

NO -Repair an open in the wire between A/T clutch pressure control solenoid valve A and ground (G101), or repair poor ground (G101), then go to step 15.
Connect the A/T clutch pressure control solenoid valve A connector.
Update the A/T software in the PCM if it does not have the latest software (see ECM/PCM UPDATE ), or substitute a known-good PCM (see SUBSTITUTING THE ECM/PCM ).
Start the engine, and wait for at least 1 second.
Check for Pending or Confirmed DTCs with the HDS.
Is DTC P0963 indicated?

YES -If the PCM was updated, substitute a known-good PCM (see SUBSTITUTING THE ECM/PCM ), then recheck. If the PCM was substituted, go to step 1.

NO -Go to step 14.
Monitor the OBD status for P0963 in the DTCs/Freeze Data in A/T Mode Menu for a pass/fail.
Does the HDS indicate PASSED?

YES -If the PCM was updated, troubleshooting is complete. If the PCM was substituted, replace the original PCM (see ECM/PCM REPLACEMENT ). If any other DTCs were indicated on step 13, go to the indicated DTC's troubleshooting.

NO -Check for poor connections and loose terminals at A/T clutch pressure control solenoid valve A and the PCM. If the PCM was updated, substitute a known-good PCM (see SUBSTITUTING THE ECM/PCM ), then recheck. If the PCM was substituted, go to step 1. If the HDS indicates NOT COMPLETED, return to step 12 and recheck.
Connect the A/T clutch pressure control solenoid valve A connector.
Clear the DTC with the HDS.
Start the engine, and wait for at least 1 second.
Check for Pending or Confirmed DTCs with the HDS.
Is DTC P0963 indicated?

YES -Check for poor connections and loose terminals at A/T clutch pressure control solenoid valve A and the PCM, then go to step 1.

NO -Go to step 19.
Monitor the OBD status for P0963 in the DTCs/Freeze Data in A/T Mode Menu for a pass/fail.
Does the HDS indicate PASSED?

YES -Troubleshooting is complete. If any other DTCs were indicated on step 18, go to the indicated DTC's troubleshooting.

NO -Check for poor connections and loose terminals at A/T clutch pressure control solenoid valve A and the PCM, then go to step 1. If the HDS indicates NOT COMPLETED, return to step 17 and recheck.
