Thank you Welcome to the forum. That is interesting, that is the first I have heard of a login password for/to reset codes. Bill Share this post Link to post Share on other sites
05 Vectra Report post Posted November 30, 2020 Thanks Bill for reaching out. Yes there is a small screen to the right of the steering wheel of the 05 Vectra that once you scroll trough it, shows a screen which will display the engine codes. Only if you know the Password. I've tried calling Cummings and Freightliner service centers and none know the Password. The codes can also be reset using the proprietary Freightliner software and a PC. I am not sure whether there is an off the shelf code reader that will read the Cummings ISL Codes even though I have come across an adapter that will connect an OBD to the 9 pin round port mounted at the rear of the engine compartment. Any comment would be appreciated. Stuck in Phoenix, AZ. Share this post Link to post Share on other sites

hermanmullins Report post Posted November 30, 2020 This is a long shot but may help. 1) Google search 2005 Vectra 2) RV Trader has 4 on their list for sale the first is a private owner. 3) There is a place that you can email the seller. The seller may have the code. You may have to try more than one. Have you reached out to Winnebago? Herman Share this post Link to post Share on other sites
wildebill308 Report post Posted November 30, 2020 (edited) If that doesn't work I would try to call Winnebago Inc. Customer Care (800) 537-1885 - Toll Free (641) 585-6939 Wish I knew more but that's the first I heard about a password for the codes. Hope that works. If that doesn't work try calling National Indoor RV Centers in Phoenix, AZ 520-442-2500 Bill Edited November 30, 2020 by wildebill308 Share this post Link to post Share on other sites
hermanmullins Report post Posted November 30, 2020 Just a thought. if the number you got doesn't work try the last 4 numbers of your VIN number and or engine serial number. Herman Share this post Link to post Share on other sites
05 Vectra Report post Posted November 30, 2020 SUCCESS !! But be careful for what you wish for... So the password 8127 allowed me to get into the SYSTEMS MONITOR, this is what it threw back at me.. H2o IN FUEL - SPN 97 CM 0 Voltage Short or above normal RNG. MI 3 OC 10 FUEL DLV PRESSR - SPN 94 CM 0 Data Valid But Below Normal RNG MI 18 OC 34 POWER SUPPLY SPN 627 CM 0 DATA INCORRECT, INT 2 OC 1 Share this post Link to post Share on other sites

kaypsmith Report post Posted November 30, 2020 I would affix the code # just below or very near the code read area with a note of what it represents, for future reference. Share this post Link to post Share on other sites
