DTC P0985 Shift Solenoid "E" Control Circuit Low (Shift Solenoid Valve SR)

DTC P0986 Shift Solenoid "E" Control Circuit High (Shift Solenoid Valve SR)


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
P0985
ECM detects short in solenoid valve SR circuit 2 times when solenoid valve SR is operated (1-trip detection logic)
  1. Short in shift solenoid valve SR circuit
  2. Shift solenoid valve SR
  3. ECM
P0986
ECM detects open in solenoid valve SR circuit 2 times when solenoid valve SR is not operated (1-trip detection logic)
  1. Open in shift solenoid valve SR circuit
  2. Shift solenoid valve SR
  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.)
