Static Testing

NOTE: You must perform the Circuit/System Testing first.

Ignition OFF, remove the PCS2 from the valve body. Refer to Control Valve Solenoid Replacement (SS1, SS2, SS3, TCC, and MAIN MOD) or Control Valve Solenoid Replacement (PCS1 and PCS2) .
Test for an open circuit between the control circuit terminal 2 and the PCS2 solenoid metal case and between the B+ circuit terminal 1 and the PCS2 solenoid metal case.
- If not within the specified range, replace the PCS2 solenoid.
Test for the specified resistance between the control circuit terminal 2 and the B+ circuit terminal 1 of the PCS2. Refer to Temperature Versus Resistance (Transmission Fluid Temperature Sensor) or Temperature Versus Resistance (Speed Sensor) or Temperature Versus Resistance (Solenoid) .
- If not within the specified range, replace the PCS2 solenoid.
Ignition OFF, remove the SS1, SS2 and SS3 solenoids from the valve body. Refer to Control Valve Solenoid Replacement (SS1, SS2, SS3, TCC, and MAIN MOD) or Control Valve Solenoid Replacement (PCS1 and PCS2) .
Test the SS1, SS2 and SS3 for an open circuit between the control circuit terminal B and solenoid metal case and the B+ circuit terminal A and solenoid metal case.
- If not within the specified range, replace the affected solenoid.
Test for resistance between the control circuit terminal B and the B+ circuit terminal A of SS1, SS2, and SS3. Refer to Temperature Versus Resistance (Transmission Fluid Temperature Sensor) or Temperature Versus Resistance (Speed Sensor) or Temperature Versus Resistance (Solenoid) .
- If not within the specified range, replace the affected solenoid.
