How to solve VCM 2 SP177C cannot read voltage on obd pin 16
VCM 2 SP177C voltage issue:
I have one of my VCM 2 SP177-C that doesn't read voltage on obd pin 16.
It does power up, but when trying to program, I get a message saying vehicle battery is low. Voltage going into vcm2 is steady 13.9v as I always use my Schumacher battery charger while programming.
The problem is inside the vcm2. Either the processor doesn't see voltage or sees a lower voltage than what comes in.
Anyone has some sort of electrical schematic of those sp177c so i could try to repair it ??
Thanks
Possible solution:
If you have new ids then car's battery needs to be like 14v.!
Get into runtime folder and edit file "batterymonitor"
