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 (12 Volts 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.

91
No internal ABS ECU solenoid voltage
available.
Verify permanent power is present.
