TROUBLESHOOTING
20.1 ERROR CONDITION OR MISSING OPERATION CONDITION
When an error condition or a missing operation condition is present on a slide-out, the green indicator
light on its respective handheld control starts blinking upon releasing of the IN/OUT rocker switch.
Turning the ignition OFF and ON again, will stop the blinking and reset the fault. If the error condition or a
missing operation condition is still present, the blinking will start again the next time that the slide-out is
operated. So, to get a fault diagnostic, use the MCD right after operating the slide-out without cycling the
ignition switch.
NOTE
It is of the utmost importance to have a MCD (message center display) in working condition because it
is the most important tool to achieve troubleshooting on a multiplex vehicle.
Fault diagnostic
To get more specific information about the error condition or the missing operation condition, request a
diagnostic from the slide-out CECM using the dashboard message center display (MCD). Check if there
are active errors in the slide-out electrical system. With the SYSTEM DIAGNOSTIC menu, highlight
FAULT DIAGNOSTIC and then highlight ELECTRICAL SYSTEM to request a diagnostic of the electrical
system from the CECM. Press the enter key. If applicable, the MCD shows the device ID, the fault
messages or fault codes recorded. When more than one fault is recorded, an arrow pointing down
appears on the right of the display. Use the down arrow to see all the fault messages.
Once the problem corrected, the MCD still shows the fault as being active. You have to leave the FAULT
DIAGNOSTIC menu, wait approximately 20 to 30 seconds and then return to FAULT DIAGNOSTIC to
request a new diagnostic of the ELECTRICAL SYSTEM from the CECM. The MCD should display the
fault as being inactive.
