Geeze, maybe it is time for a new truck.
Yesterday, I had the truck into my new shop for an oil change, lube,
tire rotation/balance plus state inspection and emissions. Everything
was fine, all passed.
Today, I start the truck up: Check engine light. Code P0601. PCM
checksum failure. Damn. "Rebooted" the truck, code reappeared second
time it was turned on. Double damn.
Coincidence that this happened right after the truck was in the shop?
Can't figure out how they'd be linked.
Anyway... maybe I'll be lucky and it'll just need to be re-flashed.
If it needs to be replaced, looks like a simple job (according to my
Chiltons), should I do that myself, then just have the dealer reflash
the new PCM if necessary? Will I be able to drive if I buy and install
an aftermarket PCM?
If the suggestion is to buy and install myself - suggestion of vendors?
Also, I keep seeing mention that this might be covered under an 8/80
Federal Emissions Warranty. Never heard of such a thing, but the
truck's still under 80k - barely - 79500!
If it's not under warranty, what am I looking for in repair costs?
This is depressing. Maybe I should just ditch the ol' gal and get
myself a new truck...
