Hello. My name is ***** ***** I will be helping you today.

Do you currently have the van or does the mechanic? If you have it do you have a multimeter and are you willing to do some testing?

Customer: replied 1 year ago.
I have it and yes I can and 8 have multimeter. Also no speedometer.
no error code because no power and in limp mode. All gear lights stay on d r n 2 1 etc. Engine light is on. just to be clear
Expert:  Wayne Crawford replied 1 year ago.

OK start by checking for power and ground on the obd connector.

I am attaching a pinout.. check for a good ground on pin 5 and power on 16.

We need to see which is missing to determine which way to go with the diagnoses.

Is power on pin 16 but no ground on pin 5
Expert:  Wayne Crawford replied 1 year ago.

K check pin 4 and see if it has a ground.

No ground pin 4 or 5 with multimeter. No ground. Sorry for previous

Lets start by checking, cleaning and tightening ground G300. I am attaching a location view on it.

I checked 20 amp fuse eat under hood was bad seems to have fixed it at least for 20 min now. Yay
Expert:  Wayne Crawford replied 1 year ago.

A fuse was not responsible for the lack of ground so the results you gave me were not accurate apparently.

Let me know if you need anything further. THanks
