Question about 1998 Cadillac DeVille
After installing the after market radio, the trip meter and average mpg resets.While installing this after market radio, if the battery was completely disconnected, then this problem occurs.When the battery is disconnected, the vehicle computer( also called ecm) looses all its settings/memory. Your average MPG should be back to normal next time you fill up.----------Also there is one more reset procedure, try this.Only disconnect the negative battery terminal of car.Let it remain unplugged for 30 minutes, then reconnect the battery terminal, this resets internal system.Then check if same problem occurs or it gets solved.If the same problem is seen then,If the trip meter and average mpg resets automatically after radio was installed, then it can be any of the radio wire getting connected to any other live wire causing the issue. Disconnect the radio wiring connection from dash and then check.If the problem, solves then, Check the radio wiring, if any wire is got crimped and cut, then insulate that wire and reconnect radio wirings as it were before.In some cars, it requires radio code, if you disconnect and reconnect radio.So take care you have your radio codes handy, before doing this.If you dont have code, then check the radio manual, which mostly comes with radio installation kit.On first or last page of manual , the radio code is mentioned.If you still do not get code, then get it from the store, from where you bought, the radio.Because with code, it will be difficult to make the radio work, after you reconnect.--------
Try this possibilities, this should help.Thanks.Helpmech.
