DTC Troubleshooting: P0962 (16)

DTC P0962:

Problem in A/T Clutch Pressure Control Solenoid Valve A Circuit

NOTE:

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

R20A3 Engine Model

Turn the ignition switch to ON (II).

Clear the DTC with the HDS.

Start the engine, and wait for at least 1 second.

Check for Temporary DTCs or DTCs with the HDS.

Is DTC P0962 indicated?

YES	-	Go to Step 8 .
NO	-	Go to Step 5 .

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 6 .
NO	-	Go to Step 8 .

In the Clutch Pressure Control Solenoid Valve Control menu, select A/T clutch pressure control solenoid valve A at 1.0 A.

Monitor the OBD STATUS for P0962 in the DTCs MENU with the HDS.

Does the HDS indicate FAILED?

YES	-	Go to Step 8 .
NO	-	If the HDS indicates PASSED, intermittent failure, the system is OK at this time. Check for poor connections or loose terminals between A/T clutch pressure control solenoid valve A and the PCM. If the HDS indicates NOT COMPLETED, go to Step 5 .

Turn the ignition switch to LOCK (0).

Jump the SCS line with the HDS.

Disconnect PCM connectors A (44P) and C (44P).

Measure the voltage between PCM connector terminals A38 and C40.

Is there battery voltage?

YES	-	Go to Step 12 .
NO	-	Check for a blown No. 7 fuse (15 A) in the driver's under-dash fuse/relay box. If the fuse is OK, repair open in the wire between PCM connector terminal A38 and the driver's under-dash fuse/relay box, then go to Step 18 .

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 14 .
NO	-	Replace A/T clutch pressure control solenoid valve A, then go to Step 18 .

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 15 .
NO	-	Repair open in the wire between A/T clutch pressure control solenoid valve A and body ground (G101), or repair poor ground (G101), then go to Step 18 .

Disconnect PCM connector B (44P).

Check for continuity between A/T clutch pressure control solenoid valve A connector terminal No. 1 and body ground.

Is there continuity?

YES	-	Repair short to body ground in the wire between A/T clutch pressure control solenoid valve A connector terminal No. 1 and body ground, then go to Step 18 .
NO	-	Go to Step 17 .

Check for continuity between A/T clutch pressure control solenoid valve A connector terminal No. 1 and PCM connector terminal B44.

Is there continuity?

YES	-	Go to Step 24 .
NO	-	Repair open in the wire between A/T clutch pressure control solenoid valve A connector terminal No. 1 and PCM connector terminal B44, then go to Step 18 .

Reconnect all connectors.

Turn the ignition switch to ON (II).

Clear the DTC with the HDS.

Start the engine, and wait for at least 1 second.

Check for Temporary DTCs or DTCs with the HDS.

Is DTC P0962 indicated?

YES	-	Check for poor connections or loose terminals between A/T clutch pressure control solenoid valve A and the PCM, then go to Step 1 .
NO	-	Go to Step 23 .

Monitor the OBD STATUS for P0962 in the DTCs MENU with the HDS.

Does the HDS indicate PASSED?

YES	-	Troubleshooting is complete. If any other Temporary DTCs or DTCs were indicated in Step 22 , go to the indicated DTC's troubleshooting.■
NO	-	If the HDS indicates FAILED, check for poor connections or loose terminals between A/T clutch pressure control solenoid valve A and the PCM, then go to Step 1 . If the HDS indicates NOT COMPLETED, go to Step 21 .

Reconnect all connectors.

Update the PCM if it does not have the latest software, or substitute a known-good PCM.

Start the engine, and wait for at least 1 second.

Check for Temporary DTCs or DTCs with the HDS.

Is DTC P0962 indicated?

YES	-	Check for poor connections or loose terminals between A/T clutch pressure control solenoid valve A and the PCM. If the PCM was updated, substitute a known-good PCM, then go to Step 26 . If the PCM was substituted, go to Step 1 .
NO	-	Go to Step 28 .

Monitor the OBD STATUS for P0962 in the DTCs MENU with the HDS.

Does the HDS indicate PASSED?

YES	-	If the PCM was updated, troubleshooting is complete. If the PCM was substituted, replace the original PCM. If any other Temporary DTCs or DTCs were indicated in Step 27 , go to the indicated DTC's troubleshooting.■
NO	-	If the HDS indicates FAILED, check for poor connections or loose terminals between A/T clutch pressure control solenoid valve A and the PCM. If the PCM was updated, substitute a known-good PCM, then go to Step 26 . If the PCM was substituted, go to Step 1 . If the HDS indicates NOT COMPLETED, go to Step 26 .
