Can anyone provide engine error codes for a 1998 Winnebego Motorhome w/GM chassis Class A Vortec 454 L-29?......and the procedure for determining them? Cant find it anywhere!

Frustrated:(,

I am asuming you mean check engine code numbers. You will need a scan tool or if you goto autozone they will usually pull them for you. If you get the numbers and send them to me I would be happy to look them up and tell you what they are. The aldl connector should be beside the doghouse on one side or the other or under the dash on drivers side. Unfortunetly the days of retriving codes with a paper clip ended in 94

well, 95 actually....
althought there was some obd2 in 95...
and yes, you'll need a scanner..

Actually, 1993 for some GM passenger cars. Like the LT1s and many 3.1L V6 FWD cars. I get calls all the time from guys trying to pull codes from those cars with a paper clip. It's pretty much plug-in proms you can, flash memory you can't.

Actually, GM started to phase in OBDII in 1994. My dad's 94 LeSabre has it.

Re: Motorhome Error codes
 

Actually, the OBD2 style connector under the dash does not make the vehicle OBD2. 1994 LeSabres were still OBD1. The '94 & '95 GM vehicles with the newer connector do not have the class 2 data terminal and wiring. The '94 & '95 Corvettes, and 1995 F body cars all have the OBD2 style connector below the dash, but are not OBD2. Actual OBD2 GM cars and trucks came along in 1996.

My 94 firebird v-6 has a obd1 plug but you can't read it with a paper clip. It's one of those bastard years tha you have to have a scan tool.

Bobby, it has a flash PCM, not a removable prom. Flash computers all need a scan tool or code reader. Not all flash computers are OBD2 however. Not until 1996.

Wondering why the paper clip wouldn't work.

Thanks for all the help guys........we took it to Auto Zone and they couldnt get a reading. They are not sure if their computer is the correct one for a Motor Home?

doubly frustrated

Re: Motorhome Error codes
 

because it don't.

although some of the really early obd2 (like some of the guys are talking about) CAN be jumped but i don't remember which terminals to jump so the smoke don't get let out....96-up yer gonna need a scanner...

btw, you can pick up code readers pretty cheap, i guess, but i like a data stream...

Re: Motorhome Error codes
 

Lynn, if it's a GM powertrain, the same scan tool, or code reader that works on a truck will work on your motorhome. I program those all the time. GM computers is all I do, all day every day. The '96/'97 454" trucks use a slightly different computer than the 1998/2000. Tell the kid at Autozone to select 1997 as the year model and he may get in. I often see motorhomes called one year newer than the chassis actually is. Probably the chassis were still on hand from the previous year when they built the motorhome.

Good luck, Ed

You can now buy a cheap scan tool from Kragen that will read any OBD2 code and give a breakdown
on any vehicle equipt with OBD2 or you get a little nicer one from Mac tools that does the same and has
some extra features such as Web updates and comes with a cable for USB. I have the MAC one and it works great lets you also Clear the codes. Cost $100.00
