"D" Control Circuit Low (Shift Solenoid Valve S4); 2015 MY Tundra [08/2014 - ]
DTC
P0982
Shift Solenoid "D" Control Circuit Low (Shift Solenoid Valve S4)
DTC
P0983
Shift Solenoid "D" Control Circuit High (Shift Solenoid Valve S4)
DESCRIPTION
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
.

CODE
DTC DETECTION CONDITION
TROUBLE AREA
P0982
ECM detects a short in the solenoid valve S4 circuit 2 times when
solenoid valve S4 is operated (1-trip detection logic).

P0983
ECM detects an open in the solenoid valve S4 circuit 2 times when
solenoid valve S4 is not operated (1-trip detection logic).

MONITOR DESCRIPTION
These DTCs indicate an open or short in the shift solenoid valve S4 circuit. When there is an open or short circuit
in any shift solenoid valve circuit, the ECM detects the problem, illuminates the MIL and stores the DTC. When
the shift solenoid valve S4 is ON, if its resistance is 8 Ω or less, the ECM determines there is a short in the shift
solenoid valve S4 circuit.
When the shift solenoid valve S4 is OFF, if its resistance is 100 kΩ or more, the ECM determines there is an open
in the shift solenoid valve S4 circuit
.
