The Body Computer M001 receives door open input signals at pin 8 of connector D (driver''s front door) and 25 of connector E (passenger side door).The puddle lights G051 and G052 are operated by the driver''s door control unit M066 and the passenger door control unit M067 connected by the CAN to the Body Computer M001.The control units M066 and M067 receive a direct supply from the battery pin 11 of connector D via the line protected by fuse F32 of the junction unit under the dashboard B002. Pin 7 of connector D of M066 and M067 is earthed.On the basis of the control logic described previously, each control unit supplies the puddle light G051 and G052 with a timed delay from pins 17 and 18 of connector B.
