Diagnostic Code LED associated with 12 Blower on the original PCM
display will light up as the number 12 on the new display. In addition,
the G-III controller indicator switch lamp will blink 12 times like the G-II
controller does.
• Figure 3: Also illustrated is the “ON” indicator meaning the heater is
powered in the normal or standby state and “Pu” indicator showing the
heater is in the Cool Down (Purge) state.
• X45 ONLY: A new error code, 14, has been added to indicate a short
circuit on the hour meter (auxiliary output) harness. For this error code,
the indicator switch lamp will blink 14 times as well.
