Circuit / System Description
The 3-4, 4-5 shift solenoid (SS) valve?(S4) controls transmission fluid pressure acting on the U1?shift valve to position the valve for the appropriate gear. The 3-4, 4-5?SS valve?(S4) is a normally open exhaust valve located on the front control valve body. The solenoid is case grounded. The output driver module (ODM), within the transmission control module?(TCM), commands the solenoid ON or OFF by providing voltage. When the 3-4, 4-5?SS valve?(S4) is commanded ON, the TCM senses high voltage. When the 3-4, 4-5?SS valve?(S4) is commanded OFF, the TCM senses low voltage.
If the TCM detects a continuous open or short to voltage in the 3-4, 4-5?SS valve?(S4) circuit, then DTC?P0983 sets. DTC?P0983 is a type?A DTC.
