DTC P0966:
 Problem in A/T Clutch Pressure Control Solenoid Valve B Circuit
NOTE:
K24Z3 engine model
  1. Turn the ignition switch to ON (II).
  1. Clear the DTC with the HDS.
  1. Start the engine, and wait for at least 1 second.
  1. Check for Temporary DTCs or DTCs with the HDS.
Is DTC P0966 indicated?
YES -
Go to Step 8 .
NO -
Go to Step 5 .
  1. Select Clutch Pressure Control (Linear) Solenoid Valve B in the Miscellaneous Test Menu, and test A/T clutch pressure control solenoid valve B with the HDS.
Does the HDS indicate NORMAL?
YES -
Go to Step 6 .
NO -
Go to Step 8 .
  1. In the Clutch Pressure Control Solenoid Valve Control menu, select A/T clutch pressure control solenoid valve B at 1.0 A.
  1. Monitor the OBD STATUS for P0966 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 B and the PCM. If the HDS indicates NOT COMPLETED, go to Step 5 .
  1. Turn the ignition switch to LOCK (0).
  1. Disconnect the A/T clutch pressure control solenoid valve B connector.
  1. Measure the resistance between A/T clutch pressure control solenoid valve B connector terminals No. 1 and No. 2.
Is there 3−10 Ω?
YES -
Go to Step 11 .
NO -
  1. Check for continuity between A/T clutch pressure control solenoid valve B connector terminal No. 2 and body ground.
Is there continuity?
YES -
Go to Step 12 .
NO -
  1. Jump the SCS line with the HDS.
  1. Disconnect PCM connector B (49P).
  1. Check for continuity between A/T clutch pressure control solenoid valve B 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 B connector terminal No. 1 and body ground, then go to Step 16 .
NO -
Go to Step 15 .
  1. Check for continuity between A/T clutch pressure control solenoid valve B connector terminal No. 1 and PCM connector terminal B40.
Is there continuity?
YES -
Go to Step 22 .
NO -
Repair open in the wire between A/T clutch pressure control solenoid valve B connector terminal No. 1 and PCM connector terminal B40, then go to Step 16 .
  1. Reconnect all connectors.
  1. Turn the ignition switch to ON (II).
  1. Clear the DTC with the HDS.
  1. Start the engine, and wait for at least 1 second.
  1. Check for Temporary DTCs or DTCs with the HDS.
Is DTC P0966 indicated?
YES -
Check for poor connections or loose terminals between A/T clutch pressure control solenoid valve B and the PCM, then go to Step 1 .
NO -
Go to Step 21 .
  1. Monitor the OBD STATUS for P0966 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 20 , 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 B and the PCM, then go to Step 1 . If the HDS indicates NOT COMPLETED, go to Step 19 .
  1. Reconnect all connectors.
  1. Start the engine, and wait for at least 1 second.
  1. Check for Temporary DTCs or DTCs with the HDS.
Is DTC P0966 indicated?
YES -
Check for poor connections or loose terminals between A/T clutch pressure control solenoid valve B and the PCM. If the PCM was updated, substitute a known-good PCM, then go to Step 24 . If the PCM was substituted, go to Step 1 .
NO -
Go to Step 26 .
  1. Monitor the OBD STATUS for P0966 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 25 , 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 B and the PCM. If the PCM was updated, substitute a known-good PCM, then go to Step 24 . If the PCM was substituted, go to Step 1 . If the HDS indicates NOT COMPLETED, go to Step 24 .
