CODE B335 - LOSS OF CRTC DATA

Circuit Description:

This code can only be displayed as "history", indicating an intermittent problem. The code cannot be displayed as "Current" since this would mean the problem is present now, and if the problem was present diagnostics could not be entered to read codes out. Code B335 will set if the ignition is on and the BCM is not able to exchange data with the CRTC. If the problem was presently occuring, the "Self Diagnostic System Check" would address the problem. If this code ever appears, the operator may indicate the CRT automatically flips to a radio function page. This intermittent problem would be caused by two opens in the data circuit, one on either side of the CRTC isolating it from the BCM, or the CRTC.

If code B335 is set as "History", along with any of the following codes set as "History"; B334, B336, B337, B552, B553, E047, see chart on "Multiple Intermittent Codes".
