Inspect Shift Solenoid Valve S

a. Remove the shift solenoid valve S2.

b. Measure the resistance between the solenoid valve terminal and solenoid valve body. Standard resistance: 11 to 15 ohms at 20°C (68°F)

c. Connect the positive (+) lead to the terminal of the solenoid connector, and the negative (-) lead to the solenoid body.

d. Check the operating sound of the solenoid valve.

description

Shifting from 1st to 5th is performed in combination with the ON and OFF operation of the shift solenoid

2006 TRANSMISSION A750F Automatic Transaxle - Sequoia valves SL1, SL2, S1, S2 and SR, which is controlled by the ECM. If an open or short circuit occurs in the shift solenoid valves, the ECM controls the remaining normal shift solenoid valves to allow the vehicle to be operated safely (See DIAGNOSIS SYSTEM ).

P0985

ECM detects short in 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

• 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

monitor description

These DTCs indicate an open or short in the shift solenoid valve SR circuit. When there is an open or short in any shift solenoid valve circuit, the ECM detects the problem and illuminates the MIL and stores the DTC. When the shift solenoid valve SR is ON, if resistance is 8 ohms or less, the ECM determines that 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 ECM determines that there is an open in the shift solenoid valve SR circuit (See DIAGNOSIS SYSTEM ).
