DTC P0982 Shift Solenoid "D" Control Circuit Low (Shift Solenoid Valve S4) Shift Solenoid "D" Control Circuit High (Shift Solenoid Valve S4)

This document provides information about diagnostic trouble codes P0982 and P0983 related to the shift solenoid valve S4 in the automatic transmission. These codes indicate issues with the low or high resistance circuit of solenoid valve S4. The monitoring strategy checks the resistance of solenoid valve S4 continuously with the ignition on. Malfunction thresholds are provided to diagnose high or low resistance faults in the solenoid valve S4 circuit. Inspection and testing procedures are outlined to diagnose the potential causes in the transmission wire, wire harness, or solenoid valve itself.

Shift Solenoid "D" Control Circuit Low (Shift


DTC P0982
Solenoid Valve S4)

Shift Solenoid "D" Control Circuit High (Shift


DTC P0983
Solenoid Valve S4)
AX DESCRIPTION
Shifting from 1st to O/D is performed in combination with the ON and OFF operation of the shift solenoid
valves SL1 and SL2, 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 (see page AX-31).
DTC No. DTC Detection Condition Trouble Area
P0982 ECM detects short in solenoid valve S4 circuit Short in shift solenoid valve S4 circuit
2 times when solenoid valve S4 is operated (1 Shift solenoid valve S4
trip detection logic) ECM
P0983 ECM detects open in solenoid valve S4 circuit Open in shift solenoid valve S4 circuit
2 times when solenoid valve S4 is not Shift solenoid valve S4
operated (1 trip detection logic) ECM

MONITOR DESCRIPTION
This DTC indicates an open or short in the shift solenoid valve S4 circuit. The ECM commands gear shifts
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, illuminates the MIL and stores the DTC. Also, the ECM
performs the fail-safe function and turns the other normal shift solenoid valves ON/OFF. In case of an
open or short circuit, the ECM stops sending current to the circuit (see page AX-31).
