Multiplex Network Body Computer No.2 (89226-53010) located in the passenger foot-well.As they are quite expensive I was wondering if you could help me determine which of these parts needs replacing?Many thanks.

By MPX-B I mean that pulling the MPX-B fuse or the DC-CUT fuse eliminates the drain. I also have the following DTC code:B1400 Normal

HI,

I am sorry that you have not been helped yet. I just came online and saw your question

Ok, I need to get the last 8 of the vin number to pull the schematics to go thru them and testing for the fault codes

Please remember that I am not there and therefore may need to ask for more information at times

HI,

Unfortunately I dont have the schematics or testing procedures for this one so I will need to opt out and see if another expert can help
