Check AdvanceTrack

Hello:

I've got a 2002 Explorer Limited with v8 and AdvanceTrac. It has
50,000 miles. Today the message center comes on with the message
"Check AdvanceTrac". In addition, the 4x4 lights will flash
occasionally and the 4x4 buttons no longer have any effect. The
AdvanceTrac icon on the dash stays lit.

Any ideas on what to check first? Will an OBDII code reader be
able to read the error codes for this sort of fault?

Thanks, Larry

It will depend on the code reader.. Some code readers can't access
proprietary modules and are designed for PCM code retrieval only. For your
concern you will need to access the 4WD module. Diagnostics will depend on
whether yours in a Job 1 or Job 2 car...
