BCM Circuit:






CIRCUIT DESCRIPTION:
You have been directed to this as a result of a total loss of communication on CKT 800. The voltage was stable at 5 volts on either pin "L" or "M" of the DLC connector. This could be due to a wiring or element problem.

NOTES ON FAULT TREE:
1. The voltage is stable at pin "M" so the fault lies between the BCM and CCDIC.
2. The voltage is stable at pin "L," therefore the fault lies between the IPC and BCM.
