Code Description
A “Miscellaneous Output Fault” code indicates an electrical
fault in an OEM specific spare output, warning lamp or buzzer.
System operation is not affected when these faults are
detected.
The troubleshooting tree first tests that the associated ECU
harness pin is not shorted to ground and is continuous to the
component. If continuity exists, the component must be
repaired or replaced.
See "Troubleshooting Tips" for general guidelines on system
diagnostics.
