P0983

DTC P0983 Shift Solenoid "D" Control Circuit High (Shift Solenoid Valve S4)

CIRCUIT DESCRIPTION

DTC Detection Condition:

Shift solenoid valve No. 4 is controlled by ECM and it switches ON and OFF of the O/D direct switch.

MONITOR DESCRIPTION

Monitor Strategy:

Typical Enabling Conditions:

Typical Malfunction Thresholds:

The ECM commands gearshift by turning the shift solenoid valves "ON/OFF". When there is an open or short circuit in any shift solenoid valve circuit, the ECM detects the problem and illuminates the MIL and stores the DTC. And the ECM performs the fail-safe function and turns the other shift solenoid valves in good condition "ON/OFF" (In case of an open or short circuit, the ECM stops sending current to the circuit.).
