S80 Fault Codes - Help! S80 1999

posted by  someone claiming to be hywel on  Thu Aug 19 04:46 CST 2004 [RELATED]

Emission Service Required was showing up and the dealer said the following codes showed up: ECM-261A, 271A and 9400. They cleaned the throttle body, and replaced the Mass Air Flow sensor, and for some reason, the brake pedal sensor. Now, I've had the occasional ABS/STC message pop up and go away in the past, but does the 9400 message relate to that in ANY way? I'm confused...

Any ideas? Cheers,

- hywel

    The ABS/STC control module on your Volvo S80 shares a lot of information and
    functions with the other computers, such as transmission and engine
    management; hence, you may have multiple trouble lights flashing randomly (Check Engine, STC, Brake Failure, Warning triangle, etc.).

    There are very good chances some of your problems are associated to a
    defective ABS control unit.

    Here's information I have on this subject.
