Test point 1
CVT drive pulley pressure control solenoid valve 2P connector No. 1
Test point 2
CVT drive pulley pressure control solenoid valve 2P connector No. 2


Is there 5.1?6.4 ??

     
YES
     
     
     
Go to step 5.
     
NO
     
     
     
Faulty CVT drive pulley pressure control solenoid valve. Replace the lower valve body, then do the repair verification.
5.
Shorted wire check (DRC+ line):

Test point 2
Body ground


Is there continuity?

     
YES
     
     
     
Go to step 6.
     
NO
     
     
     
Check for a short DR LS/DRC+, and check for poor connections or loose terminals between the CVT drive pulley pressure control solenoid valve and the PCM, then go to step 1 and recheck.
6.
Determine shorted wire in either solenoid wire harness A or B (DRC+ line):

Determine shorted wire in either solenoid wire harness A or B (DRC+ line)
?1.

Test circuit
DRC+
Test point 1
Solenoid wire harness A 6P connector No. 1 (RED)
Test point 2
Body ground


Is there continuity?

     
YES
     
     
     
Repair a short to body ground in the DRC+ wire between the solenoid wire harness A 6P connector and the solenoid wire harness A 8P connector, then do the repair verification.
     
NO
     
     
     
Repair a short to body ground in the DRC+ wire between the CVT drive pulley pressure control solenoid valve and the solenoid wire harness B 6P connector, then do the repair verification.
Repair verification (OBD STATUS check):

?6.
Monitor the OBD STATUS for P0962 in the DTCs MENU with the HDS.
DTC Description
OBD Status
P0962 CVT Drive Pulley Pressure Control Valve Circuit Low
  


Does the HDS indicate PASSED, FAILED, or NOT COMPLETED?

     
PASSED
     
     
     
Troubleshooting is complete. If the PCM was substituted, replace the original PCM. Check for other DTC after this troubleshooting. If any other Pending or Confirmed DTCs were indicated, go to the indicated DTC's troubleshooting.?
     
FAILED
     
     
     
Troubleshooting is incomplete. Check for poor connections or loose terminals between the CVT drive pulley pressure control solenoid valve and the PCM, then go to step 1 and recheck. If the PCM was updated, substitute a known-good PCM, and check the OBD STATUS again.
     
NOT COMPLETED
     
     
     
Repair verification is incomplete. Meet the test condition, and check the OBD STATUS again.
