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.
If Code 335 is retrieved, check circuits No. 807 and No. 801 from the central power supply for an open. Check data communication circuit to BCM. If circuits are okay, check for intermittent contacts. If okay and fault continues, replace CCDIC panel.
