Hello. I am currently...

Hello. I am currently having 2 issues - I am not sure wether they are connected to each other. I am currently having 2 error codes "bcm-0094" and "CEM-1a64". also i get a warning light and a message saying anti skid service required

Mechanic's Assistant: Do you have the trouble code? Do you have a code reader or scan tool?

My local mechanic took the codes out for me

Mechanic's Assistant: I'll pass this info along to the Volvo Mechanic so that he can get you a quick fix. What is the model of your '94 Volvo?

My Volvo is an 2004 XC90 D5 AWD

Mechanic's Assistant: Are you fixing your XC90 yourself? What have you tried so far?

I am fixing the Volvo myself, the anti skid service required message occured after changing the rear brake pads and discs. so far i have not tried anything

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

Not at the moment

I would like to repair it myself, I was simply wondering why the cem and the bcm are related and what could have caused this issue. For now I am giving it a shot myself before taking it to a dealer. Thank you for your response

there is a wire connection between the BCM & DEM differential electronic module

it is either bcm bad , dem bad or wiring in between , there can bus line area network where all modules needs to shake hands each time you turn switch from off to on or start ,if one is missing or more on the line,it will trigger these faults

the most common is bcm itself but testing is needed ,either of these module will require relearn using dealer or capable scanner

THIS IS THE TEST PROCEDURE BUT YOU NEED SCANNER AND TOOLS
