B335

BCM Code B335:

BCM Circuit:

CIRCUIT DESCRIPTION:
Code B335 will set if the ignition is "ON" and the BCM loses data communication with the Combo Panel. Since a loss of data communication with the Combo Panel will result in a "SYSTEM FAULT" display, this code can only be recognized as a "History" code. During this event, the HVAC will divert to 75°F set temperature, front defrost air delivery and automatic blower control.

With a two-way, redundant communication ability built into this system, a double open in the data line must occur to set the fault. A single fault, however, in the Combo Panel power or ground or a loss of +10 volt wake-up to the combo panel would also cause this code to set.
