odometer flashing gauges out

[bonniepurplept]

I am a brand new member...love my purple woody 2001 PT Cruiser. Bought it about 18 months ago with 55,000 miles now has 94,000 (we drive a lot).
It has been fabulous. Today while driving my check engine, air bag and brake light came on. My odometer began flashing with the reading and the
"no bus" or "no bu5" code. (once before we got a "no fuse" code so this may be what it is trying to say). My odometer, tacometer and heat gauge are not working. My fuel gauge is working. My husband tried checking the fuses (in box inside car by drivers side) but found nothing and he had to go to work. I just found this site and hope you can help me. I have already found and copied ObiMatt87's info on " IOD fuse effects and replacement hints". I also tried to see if my car would show the codes by turning the key on and off three times but did not show anything....may not work on older model like mine.
Any advice or help is greatly appreciated and will be given to my husband who is the one who does our car repairs. thanks, Bonnie

Bonnie,

Welcome to the forum. First; turning the key trick started with the 2001 cruiser and they all show the codes if done right. Turning the key 3 times and leaving it the last time turned towards the windshield has to be done in 5 seconds or less to work. If no codes are stored, it will flash "done".

You already probably have the anser to your question as being the IOD fuse. It's located in the engine compartment in a black oblong box on the drivers side. You'l have to remove parts of the air filter system to get at it.

Good luck.

No bus means that the CCD bud is not working. Could be a fuse, a wire issue or a computer issue. The turn the key 3 times trick will probably not work because of no bus communication. You are going to need either a Chrysler DRB3 scan tool or a good aftermarket scan tool. You'll have to check which modules are communicating on the bus, if any and then go from there.

Thanks for your response. I don't know what CCD stands for. I don't have any electrical diagnostic tools so I'm probably headed to the mechanic, but I can check for connections, fusable links, etc. if I know where to look. I have checked all the fuses inside and under the hood. Thanks again for your help.
