c. Connect the battery's positive (+) lead to the terminal of the solenoid valve connector, and the

negative (-) lead to the solenoid valve body. Then check that the valve moves and makes an
operating noise.

OK: Valve moves and makes an operating noise.

DTC P0982, P0983: SHIFT SOLENOID "D" CONTROL CIRCUIT LOW (SHIFT SOLENOID VALVE
S4); SHIFT SOLENOID "D" CONTROL CIRCUIT HIGH (SHIFT SOLENOID VALVE S4)

DESCRIPTION

Shifting from 1st to 6th is performed in combination with ON and OFF operation of the shift solenoid valves
SL1, SL2, S1, S2, S3, S4 and SR, which are controlled by the ECM. If an open or short circuit occurs in any of
the shift solenoid valves, the ECM controls the remaining normal shift solenoid valves to allow the vehicle to be
operated safely. Also, the ECM stops sending current to the open or short circuited solenoid (see FAIL-SAFE
TABLE ).
