AUTOMATIC TRANSMISSION SYSTEM (for 1KD-FTV), Diagnostic DTC:P0985, P0986

DTC Code DTC Name
P0985 Shift Solenoid "E" Control Circuit Low (Shift Solenoid Valve SR)
P0986 Shift Solenoid "E" Control Circuit High (Shift Solenoid Valve SR)

DESCRIPTION

Shifting from 1st to 5th is performed in combination with the ON and OFF operation of shift solenoid valves SL1, SL2, S1, S2 and SR, which are controlled by the TCM. If an open or short circuit occurs in one of the shift solenoid valves, the TCM controls the remaining normal shift solenoid valves to allow the vehicle to be operated smoothly. In the case of an open or short circuit, the TCM stops sending current to the circuit. For details, refer to the fail-safe chart Click here.

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

  • Short in shift solenoid valve SR circuit

  • Shift solenoid valve SR

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

  • Open in shift solenoid valve SR circuit

  • Shift solenoid valve SR

  • TCM

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 TCM detects the problem, illuminates the MIL and stores the DTC. When shift solenoid valve SR is on, if its resistance is 8 Ω or less, the TCM determines there is a short in the shift solenoid valve SR circuit.

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

      *a

      Component without harness connected

      (Shift Solenoid Valve SR)

      Remove 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
