7A-36 AUTOMATIC TRANSMISSION (AW30-40LE)

CODE 32 SHIFT SOLENOID S2 (OPEN/SHORTED CIRCUIT)

UBS

D07R200026

TF

D07R200018

Circuit Description:

The solenoid S2 changes the hydraulic route with the
signals from the TCM according to the vehicle speed
and the throttle opening to control shifting. When the
solenoid S1 or S2 fails, the hydraulic circuit is
mechanically operated as a backup.

Test Description:

The following numbers correspond to the step numbers
on the diagnostic chart.
2. With the key “ON”, the voltage between the TCM

terminal (12) and ground terminal (24) is 1 V or
less.

5. When the driving wheels revolve with the 2nd

speed gear, the voltage is 8 to 16 V.

3. 6. 8. 11. The solenoid resistance is within the range

of 11 to 15 Ω (20 ℃).

Diagnostic Aids:

In case of faulty connection , open or shorted circuit to
the TCM terminal (12), code 32 is displayed.
A intermittent failure may be caused by a poor
connection, rubbed through wire insulation or a wire
broken inside the insulation.
