AUTOMATIC TRANSMISSION SYSTEM (for 1VD-FTV with DPF), Diagnostic DTC:P0982, P0983

DESCRIPTION

Shifting from 1st to 6th is performed in combination with the 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).

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 higher, the ECM determines there is an open in the shift solenoid valve S4 circuit (Click here).

   CHECK HARNESS AND CONNECTOR (NO. 1 TRANSMISSION WIRE - ECM)

   
   

   1. Disconnect the ECM connector.

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

      Standard Resistance
      Table 2. for LHD Tester Connection Condition Specified Condition C45-6 (S4) - Body ground 20°C (68°F) 11 to 15 Ω
      Table 3. for RHD Tester Connection Condition Specified Condition C46-6 (S4) - Body ground 20°C (68°F) 11 to 15 Ω

   INSPECT SHIFT SOLENOID VALVE S4

   
   
   1. 

      Remove the shift solenoid valve S4.

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

      Standard Resistance
      Tester Connection Condition Specified Condition Shift solenoid valve S4 connector terminal - Shift solenoid valve S4 body 20°C (68°F) 11 to 15 Ω

   3. Apply 12 V battery voltage to the shift solenoid valve and check that the valve moves and makes an operating noise.

      OK
      Measurement Condition Specified Condition Battery positive (+) → Shift solenoid valve S4 connector Battery negative (-) → Shift solenoid valve S4 body Valve moves and makes an operating noise
