VCM 2 SP177-C voltage issue:
I have one of my VCM 2 SP177C 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 ??
If you have new ids then car’s battery needs to be like 14v.!
Get into runtime folder and edit file “batterymonitor”
Something like this::::
MaxLowVoltage = 11600
MinMediumVoltage = 11500
MaxMediumVoltage = 12000
MinHighVoltag = 12800
Then try again.!
