  1. Can it be deleted? Keeps killing batteries and alternators!! Serging power up to 15.5 volts then drops to 10 volts, my scan tool freaked out cuz everything had codes!! High volts and low volt codes on all systems!!! Holy crab apples!! i think it’s the unit right off the positive bat side with diodes and chips! I would like to just cut it out! What do you think??

Of course not. No control unit = no power.

If you want real help, you'll need to post your codes + definitions.

You can look them up on obd-codes.com
