BCM-To-PCM Data Malfunction In Circuit No. 526

If BCM fails to receive data from PCM terminal C10 on circuit No. 526, Code F32 sets immediately and BCM will stop sending data to PCM on circuit No. 491. When PCM stops receiving data on circuit No. 491, it will set Code E47 in its memory.

However, this code will not be displayed because it would have to be sent on circuit No. 526 to BCM. Loss of data to BCM will result in a faulty instantaneous fuel economy reading of "0" MPG at all times.
