Power on Yellow valve channel.
Dump solenoid out shorted to Permanent
Power on Red valve channel.
Dump solenoid out shorted to Permanent
Power on Blue valve channel.

Low supply voltage fault. This code is not
stored in memory.
No internal ABS ECU solenoid voltage
available.
Power input over voltage fault.
Short circuit on ABS ECU internal relay.
ABS Corrupt Memory
ABS Corrupt Memory
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.
Verify 12 V DC power source.
Do Not Use Battery Charger as
Power Supply. ECU minimum
operating voltage is 8.5 V DC.
Verify permanent power is
present.
Verify 12 VDC power source.
Do Not Use Battery Charger as
Power Supply. ECU maximum
operating voltage is 16.0 VDC.
