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

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

for Preparation Click here


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 (Click here).

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

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 (Click here).
