DTC P0985: Shift Solenoid "E" Control Circuit Low (Shift Solenoid Valve SR); DTC P0986: Shift Solenoid "E" Control Circuit High (Shift Solenoid Valve SR) [08/2015 - 08/2017]: Description

WARNING: This page is about a different variant/trim than selected.

Shifting from 1st to 6th is performed in combination with 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 the current to the open or short circuited solenoid (Refer to FAIL-SAFE CHART [08/2015 - ] ).

DTC Code DTC Detection Condition Trouble Area

  • Short in shift solenoid valve SR circuit
  • Shift solenoid valve SR
  • ECM
P0986 ECM detects open in 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
  • ECM
