Output leakage or poor insulation on any of the valve channels.
Modulator valve solenoid failure or valve cable damage. Indicates that the solenoid or its cable has a short circuit to positive power (12V DC). The most likely cause is a damaged cable or solenoid. Disconnect the indicated solenoid and check the resistance at the solenoid pins. If solenoid checks good and 80-89 code still exists, check ECU.

Low supply voltage fault. This code is not stored in memory.
Verify 12V DC power source. Do Not Use Battery Charger as Power Supply. ECU minimum operating voltage is 8.5V DC.
XX
91
No internal ABS ECU solenoid voltage available.
Verify permanent power is present.
XX
92 Power input over voltage fault.
Verify 12V DC power source. Do Not Use Battery Charger as Power Supply. ECU maximum operating voltage is 16V DC.
