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
Based on the ON-OFF combinations of the SL1, 2, 3, 4 and 5, SLT, SLU, SL and SR solenoids, the TCM performs gear shifts from 1st gear to 8th gear. If a line related to a solenoid valve is open or shorted, the TCM uses the fail-safe function to turn other solenoid valves ON or OFF. If all solenoid valves are malfunctioning, only the mechanical fluid pressure circuit will function and the system will change to manual transmission. If an open or short has occurred, the TCM cuts power to the malfunctioning solenoid valve.

P0985-P0986:

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 the shift solenoid valve SR is ON, if resistance is 8 Ohms or less, the TCM determines there is a short in the shift solenoid valve SR circuit.

When the shift solenoid valve SR is OFF, if resistance is 100 kOhms or more, the TCM determines there is an open in the shift solenoid valve SR circuit.
