My name is ***** *****. I have a 2001 Safari Trek with a P32

Customer Question

My name is ***** *****. I have a 2001 Safari Trek with a P32 chassis. I get no response when I plug a Scangauge II into the OBD2 port. Checked the cig lighter fuse. It's fine. What other circuit would power that port?
JA: Thanks. Can you give me any more details about your issue?
Customer: The scangauge display does not light up, as if it is getting no power from the OBD2 port. Scangauge trouble shooting manual say's check the cigarette lighter fuse. That fuse is fine. What other fuse could be the culprit?

Hello, my name is ***** ***** be a 15 amp fuse in the chassis load center / fuse block that is labeled something like eng.-batt.This fuse supplies 12v + to socket#16 of the datalink connector.Socket #4 should be a good ground.Communication from the control module is done through socket #2 See the diagram for reference.

Thanks Joe,I located a fuse block under the hood which contains 3 different 15A fuses. Tested them all, all good. There's another fuse block under the dash, but no 15A fuses there. Any idea where else I should look?Jim
Expert:  Joe replied 1 year ago.
Typically, the chassis fuse block will be located in front of the drivers area, behind the hood.Have you verified that there is not battery voltage at #16 socket in the diagnostic connector?If there is battery voltage on #16, you must make certain there is a good ground on #4. Joe
