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 the ON and OFF operation of the shift solenoid valves SL1, SL2, SL3, S4 or 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 (RAV4_ACA30 RM000000O8L0BDX.html).

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

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 (RAV4_ACA30 RM000000O8L0BDX.html).

  1. Disconnect the transmission wire connector.

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

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


NG
Go to step 3
OK


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

  1. Connect the transmission wire connector.

  1. Disconnect the ECM connector.

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

    Standard resistance:
    Tester Connection
    		Condition
    		Specified Condition
    B96-7 (S4) - Body ground
    		20°C (68°F)
    		11 to 15 Ω


NG
REPAIR OR REPLACE HARNESS OR CONNECTOR
OK

  1. Remove the shift solenoid valve S4.

  1. Measure the resistance between the solenoid valve terminal and solenoid valve body.

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

  1. Connect the battery's positive (+) lead to the terminal of the solenoid valve connector, and the negative (-) lead to the solenoid body. Then check that the valve moves and makes an operating sound.

    OK:
    Valve moves and makes operating sound.
