poor connection, bending, corrosion, contamination, deterioration or damage. Repair or replace as
necessary and go to "VERIFICATION OF VEHICLE REPAIR" procedure.

NO



Go to "TERMINAL & CONNECTOR INSPECTION" procedure.

TERMINAL & CONNECTOR INSPECTION

Refer to DTC P0750.

POWER SUPPLY CIRCUIT INSPECTION

Refer to DTC P0750.

SIGNAL CIRCUIT INSPECTION

1. Check signal circuit open inspection

1. Ignition "OFF".

2. Disconnect "A/T SOLENOID VALVE" connector and "PCM/TCM" connector.

3. Measure resistance between terminal "10" of the ATM SOLENOID VALVE harness connector and

terminal "44" of the PCM/TCM harness connector.

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.
