Question about Isuzu Cars & Trucks

1 Answer

I had my newerto me2003 Isuzu NPR Gas5.7LBox Truck Rust Proofed recently,cause I live in Ohio.Now the running lights don't work,and the BRAKEdash light is on.Any help with these 2 issues?

The regular lights work off the turn signal stalk OK still.Also,the running lights are ONLY the headlightsthat's how the system is set up-like most of them I think. Also the dash indicator for the running lights: a green lit headlight shaped shining icon,no longer is working. As far as the BRAKEdash light goes,when I bought the truck,it was on,but I just needed to add DOT 3 fluid to the MC Reservoir to get it to shut off. Since I picked the truck up after the frame/chassis/box rust proof job,this light is now ON again.There is still plenty of DOT3 fluid in the MC ReservoirI checked,and there is no leaks or brake issues eitherI drove it several times-as far as I know. Can anybody answer these? I believe this truck has ABS-at least it has an icon on the dash that self-tests when you turn the key ON. My older Isuzu1997,did not have ABS. THANK YOU for your help with these!

NPR trucks , are hard to find books on.
its a heavy truck
seems like the spray on coating (rust proofing)
has invaded a wire to body, ground connection
or got in to a connector.
this can happen.
to fix electric, one buys a schematic first
then uses a voltmeter $10 tool to find this.
I see no online books on NPR.
get one from Isuzu?
heavy means over 4000 lbs, in USA
you are like the 7 th person ever to say county and 1st the state.
Im shocked to the core, what a savvy guy you are.!!!
good luck to you.

Would my 2003 CIVIC have been rust proofed from HONDA?


Don't say where you live and what conditions are like-- I wouldn't  bother-- Honda's and other modern cars don't benefit from rustproofing. Not worth it.
