HDS.
Go to step 6.
Go to step 8.
6. Start the engine with the shift lever in P, and wait for at least 1 second.
7. Monitor the OBD STATUS for P0976 in the DTCs MENU with the HDS.
Go to step 8.
If the HDS indicates PASSED, intermittent
failure, the system is OK at this time. Check for
intermittent short to body ground in the wire
between shift solenoid valve B and the PCM. If the
HDS indicates NOT COMPLETED, go to step 5.
8. Turn the ignition switch to LOCK (0). 9. Jump the SCS line with the HDS.

by the test result, but if the HDS has not determined
the cause of the failure, go to step 11. If any part
was replaced, go to step 12.
11. Inspect A/T clutch pressure control solenoid valve A (see page 14-219).
Repair the hydraulic system related with shift
valve E, or replace the transmission, then go to step
14.
