Electrical problems.

Post by newMercowner69 » Tue 05 Dec, 2017 1:59 pm

After fully charging the battery after Werner/Wilhelm locked me out&kicked me out last week,
Now what's happening is hazard lights come on even though i've NOT depressed the hazard light button &NO indicators working,
&low coolant light's displayed although temperature gauge is reading normally!,
SHOULD i've got the onboard computer reset AFTER charging the battery?,
The Hazard lights come on at same time as indicator's clicked on! :(.

ECU in these cars is dumbarse. No reset.

You need to resync the key with the immobilizer.
If you have the books - the method is in there.
If you don't YouTube is your friend. Take note that there are different sync methods you need to try them all before your keys might sync.
