No power on dash,radio,parking lights and plug for emission test


Check the fuses against a dark piece of paper. I have had some look OK but looking closer against a dark background showed a crack. I had a Toyota that thought it didn't have any gas and would run intermittently. Checked all sorts of things and it was a 15 cent fuse.

Mazda miata computer not comminicating to obdII


You likely just have a blown fuse at the diagnostic connector, check to see that you have 12 volts at pin 16 on the connector. See diagram of pin below.

Emission test


Why aren't they just using the OBD II port instead of the dynomometer? Which state are you in? In Washington, where I work as an emission test specialist, we don't even use the dyne (rollers) to do the test. The OBD II port doesn't require the car to be taken out of park.
If you have to resort to it, just pull the TCS fuse for the test. The TCS won't activate and you won't get any emissions error codes.
Be sure to check with the testing facility before you do this. They may not allow it if it may be considered a safety issue.
I wish you the best!

Can't access on-board codes at all, '98 S10.


I would recommend checking the fuse that controls the cigarette lighter.... i know it sounds strange, but most manufacturers link the power to the OBD test port to the same fuse as the cigarette lighter, mainly because it would be the least used accessory in the vehicle. Hope this helps.

Instrument panel cluster gauges and odometer has stopped working


I had all my analog instrument panel gauges stop working after they did the state emissions test. I found the proper fuse in the fuse block located under the hood. Simply unplugged the fuse, noticed it was still good, and plugged the same fuse (10A) back in and all the gauges started working again. Guess it needed a reset atfer they plugged in for the emissions.

hi,  this got fixed . . . all my fuses i checked WERE good . .  BUT, i had taken out my dome light fuse to replace another similar fuse that had blown . . . the mechanic at Honda let me know that the diagnostic system runs through the domelight fuse for some reason - once that fuse was replaced, it was good to go!
