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).

DTC Code DTC Detection Condition Trouble Area
P0985 The ECM detects a short in the solenoid valve SR circuit 2 times when the solenoid valve SR is operated (1 trip detection logic).

  • Short in shift solenoid valve SR circuit

  • Shift solenoid valve SR

  • ECM
P0986 The ECM detects an open in the solenoid valve SR circuit 2 times when the solenoid valve SR is not operated (1 trip detection logic).

  • Open in shift solenoid valve SR circuit

  • Shift solenoid valve SR

  • ECM

MONITOR DESCRIPTION

These DTCs indicate an open or short in the shift solenoid valve SR 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 SR is ON, if its resistance is 8 Ω or less, the ECM determines there is a short in the shift solenoid valve SR circuit.

When the shift solenoid valve SR is OFF, if its resistance is 100 kΩ or higher, the ECM determines there is an open in the shift solenoid valve SR circuit (Click here).

    INSPECT NO. 1 TRANSMISSION WIRE (SHIFT SOLENOID VALVE SR)


    1. A0157O4E13

      Disconnect the No. 1 transmission wire connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      6 (SR) - Body ground 20°C (68°F) 11 to 15 Ω

    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 1. for LHD
      Tester Connection Condition Specified Condition
      C45-5 (SR) - Body ground 20°C (68°F) 11 to 15 Ω
      Table 2. for RHD
      Tester Connection Condition Specified Condition
      C46-5 (SR) - Body ground 20°C (68°F) 11 to 15 Ω

    INSPECT SHIFT SOLENOID VALVE SR


    1. A0159SDE01

      Remove the shift solenoid valve SR.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      Shift solenoid valve SR connector terminal - Shift solenoid valve SR 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 SR connector

      • Battery negative (-) → Shift solenoid valve SR body

      		 Valve moves and makes an operating noise
