We unhooked an AC connection today and then rehooked it under the hood and got the SERVICE ELECTRIC VEHICLE SYSTEM and a code P167B code, How can we clear this code without going to a dealer? On the gas models you could pump the gas pedal three times with the ignition switch on. How do you clear it with the electric model?

How do you clear Service Electric Vehicle System light?
Code-clearing methods are the same as if the car won't start:

- OBD
- 10 to 50 key cycles, each with 3+ minutes off
- 12V disconnect
- HV disconnect

If you don't already have OBD, you should read #6 here:

We have AlfaOBD and OBDLink LX but no yellow cable yet. Can you please spell out the step by step and will I need the cable?
You might only need the yellow cable if the odometer is flashing, but either way, you can access many modules without it...:
Before connecting OBD, have the key OFF, & then turn it ONLY ONE CLICK to "MAR", NOT 2 clicks to "AVV". Click to enlarge:
![]()
Then Alfa connects to the car with the LX the same as with the KW902 shown here:
![]()
That example is for the Battery Pack Control Module. Other modules connect the same. Just go back to the home screen & select whatever module you want to check, where it will show right on the screen whether or not the yellow cable is required:
![]()
For all the modules that don't need it you can do a code check:
![]()
Then clear faults:
![]()
Make sure you follow any on-screen instructions for key position, although I think my first step above usually covers that ("ignition" ON, but not twisted far enough to "start" the "engine").

Sorry not understanding. First you said 10 to 50 key cylces along with other steps and now you are saying just clear codes. Is it one or the other or both?
One or the other, not both. Key cycles are when you do not have a OBD2 dongle and AlfaOBD. Clear codes are when you have the dongle.

Right, & if one of the steps doesn't work you try another*, but always, ALWAYS leave the humidity sensor disconnected, at least until after every issue is resolved.
* For example, if a couple of 3-minutes-off key cycles doesn't work, try OBD code clearing & if that doesn't work try a 12V disconnect, & if that doesn't work try HV disconnect & then try OBD again. Sometimes it's easier for me to describe just going all-out from the start, by disconnecting 12V, then HV for 30+ hours, then reconnect & clear in OBD.
As I mentioned above, please see #3 here:
