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

Shifting from 1st to 5th is performed in combination with "ON" and "OFF" operation of the shift solenoid valves SL1, SL2, SL3, S4 and SR which are controlled by the ECM. If an open or short circuit occurs in either of the shift solenoid valves, the ECM controls the remaining normal shift solenoid valves to allow the vehicle to be operated smoothly (Fail safe function).

DTC No.
DTC Detection Condition
Trouble Area
P0982
ECM detects short in 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 open in 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

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 and illuminates the MIL and stores the DTC. And 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.)

INSPECTION PROCEDURE

1.INSPECT TRANSMISSION WIRE (S4)


    Camry. Acv40 Gsv40.U250E Automatic Transaxle.Automatic Transaxle System. Dtc P0982 Shift Solenoid D Control Circuit Low (Shift Solenoid Valve S4)

  1. Disconnect the transmission wire connector from the transaxle.

  1. Measure the resistance according to the value(s) in the table below.

    Standard resistance:
    Tester Connection
    		Specified Condition
    20°C (68°F)
    3 - Body ground
    		11 to 15 Ω


NG
Go to step 3
OK


2.CHECK HARNESS AND CONNECTOR (TRANSMISSION WIRE - ECM)


    Camry. Acv40 Gsv40.U250E Automatic Transaxle.Automatic Transaxle System. Dtc P0982 Shift Solenoid D Control Circuit Low (Shift Solenoid Valve S4)

  1. Connect the transmission connector to the transaxle.

  1. Disconnect the connector from the ECM.

  1. Measure the resistance according to the value(s) in the table below.

    Standard resistance:
    Tester Connection
    		Specified Condition
    20°C (68°F)
    C24-78 (S4) - Body ground
    		11 to 15 Ω


NG
REPAIR OR REPLACE HARNESS OR CONNECTOR
OK

REPLACE ECM

3.INSPECT SHIFT SOLENOID VALVE (S4)


    Camry. Acv40 Gsv40.U250E Automatic Transaxle.Automatic Transaxle System. Dtc P0982 Shift Solenoid D Control Circuit Low (Shift Solenoid Valve S4)

  1. Remove the shift solenoid valve S4.

  1. Measure the resistance according to the value(s) in the table below.

    Standard resistance:
    Tester Connection
    		Specified Condition
    20°C (68°F)
    Solenoid Connector (S4) - Solenoid Body (S4)
    		11 to 15 Ω

  1. Connect the positive (+) lead to the terminal of the solenoid connector, and the negative (-) lead to the solenoid body.

    OK:
    The solenoid makes an operating sound.
