DTC P0885 A/T RELAY CIRCUIT MALFUNCTION 

GENERAL DESCRIPTION 

The HIVEC Automatic Transmission supplies the power to the solenoid valves by way of a control relay. When 
the 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. (Fail Safe Mode). 

DTC DESCRIPTION 

The TCM checks the A/T control relay signal by monitoring the control signal. If, after the ignition key is 
turned on, a voltage value that is out of specification is detected, the TCM sets this code.
