BCM Code B335, Loss Of CCDIC Data

Since a loss of data communication with CCDIC will result in SYSTEM PROBLEM display, this code can only be recognized as a history code. During a failure, the A/C-heater programmer will default to 75°F set temperature, front defrost air delivery and automatic blower control.

With a 2-way, redundant communication ability built into this system, a double open in data line must occur to set fault. A single fault; however, in the CCDIC power or ground would also cause this code to set.
