circuit.
RIGHT SIACM, LOSS OF IGNITION RUN-START - ACTIVE
When Monitored: With the ignition in the run or start position the Right SIACM
monitors the SIACM Run-Start Driver circuit for proper system voltage. This is an active
trouble code only.
Set Condition: If the voltage on the SIACM Run-Start Driver circuit is below 4.0 volts,
the code will set.

When Monitored: With the ignition in the On position and the Right SIACM transmitting
information on the PCI BUS.
Set Condition: The code will set if the Right SIACM cannot detect the Right SIACM
transmitting information on the PCI BUS for 4 consecutive seconds. NOTE: Any PCI Bus
Failure will cause this code to set.
