4.1 SYSTEM AND COMPONENT
DIAGNOSTICS
The G-II PCM continually monitors the PROHEAT operating conditions. If the G-II
PCM detects a problem, the indicator light flashes a diagnostic code(s) on
the G-II PCM status LED.
The diagnostic indicator light may also be located:
• In the toggle of the ON/OFF Switch provided by PROHEAT (standard
installation kit).
• In the PROHEAT Timer manual ON light (red).
• In an OEM indicator light package.
• In the remote switch (PROHEAT P/N PK0091) used for troubleshooting.

It is possible to have one or more diagnostic codes displayed. Codes are displayed
by a series of short flashes (that corresponds to the number of the Diagnostic
code) then turned off for 2 seconds and then the next code is displayed.
Note: The Same code is displayed only if one diagnostic code is active.
For example if a 7 and 10 Diagnostic Code occurs together, the G-II PCM status
light will flash Red 7 times then pause for 2 seconds then flash Red 10 times.
Similarly the remote ON/OFF Switch, Timer red manual light (T-II Timer will also
display the code on LCD) or OEM indicator light (installation options) will flash 7
times, pause and then 10 times.
