description

Shifting from 1st to 5th is performed in combination with the ON and OFF operation of the shift solenoid valves SL1 SL2 SI S2 and SR which is controlled by the ECM If an open or short circuit occurs in the shift

P0977

ECM detects open in solenoid valve S2 circuit 2 times when solenoid valve S2 is not operated. (1 trip detection logic)

• Open in shift solenoid valve S2 circuit

• Shift solenoid valve S2

• ECM

monitor description monitor description

These DTCs indicate an open or short in the shift solenoid valve S2 circuit. 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. When the shift solenoid valve S2 is ON, if resistance is 8 ohms or less, the ECM determines that there is a short in the shift solenoid valve S2 circuit.

When the shift solenoid valve S2 is OFF, if resistance is 100 kohms or more, the ECM determines that there is an open in the shift solenoid valve S2 circuit (See DIAGNOSIS SYSTEM ).
