Code P0885 Hyundai Description

The Hyundai Integrated Vehicle Electronic Control (HIVEC) Automatic Transmission supplies the power to the solenoid valves by way of a control relay. When the Transmission Control Module (TCM) sets the relay to ON, the relay operates, and the battery power is supplied to all the solenoid valves. When the TCM sets the relay to OFF, all solenoid valve power is shut off and the transmission is held in the 3rd gear position. The TCM checks the A/T control relay signal by monitoring the control signal. If, after the ignition key is turned on, an unexpected voltage value, which is quite a bit lower than battery voltage is detected, the TCM sets this code.
