Backup Batteri


Recommended Posts

Hej!

Är det någon vet om det finns någon form av backup batteri till kretsarna.

Typ när min bil varit avstängd i 5 min återgår den alltid från metrik

till engelsk info. Typ från km till miles.

Cadillac Seville STS 1998

Det finns "alltid " linjer till PZM (kroppskontroll modul) och andra moduler som håller dem vid liv när nyckeln är avstängd. Den djupaste sömn bilen drar cirka 0,05 ampere, vilket räcker för flera moduler, och stöldskydd, svar på nyckelbricka minnas alternativknapparna , de IPM inställningar såsom metriska / brittiska inställningar och andra funktioner fortsätter att arbeta . Om du förlorar de metersystemet / brittisk inställningar, skulle jag leta efter en sprucken eller dålig säkring, eller ett batteri som faller under 9 volt vid start av bilen.

First, be sure and check your battery cables, particularly between the spades in the positive terminal.

If the battery drops below 9 Volts, it's either discharged or about to fail any minute. If putting a good trickle charger on it overnight doesn't get your battery back in shape, you should get a new one.

If the battery voltage drops below 9 Volts, several modules will throw a code that tells the system that they may not operate properly during startup. Modules will drop codes, throw spurious codes, or even lock up if the battery voltage drops below 9 Volts.
