I've had my Pedal commander from the summer of 2018 with no issues until late October of 2019. I left work, drove a half mile to the liquor store, medicinal purposes only, then got right onto the highway. less than 1000 ft the truck goes into limp mode due to a throttle fault. I pulled over, turned off engine & restarted, pulled back out onto road and instantly got the fault. pulled back over, disconnected the pedal commander, restarted and back onto road, no issues getting home but I recall having a CEL light. Code pulled gave something like a throttle overvoltage or out of range, I don't recall since it's been months. I was too busy back then to F with it and didn't want to take a chance of being stranded in freezing cold or 2 ft of snow, which never happened due to warm winter, & have left it off for the winter. Today I got the PC hooked back up & took it for a ride. PC worked great, no issues.
Back in January I bought a battery analyzer meter, cheap about $30 but looked interesting on youtube. I tried it out on my truck, I wasn't having any starting or battery issues I just wanted to test the meter. Well I connected the leads to my battery & was surprised to see 11.8v which I did verify with a good DVM. Next the meter said to start the vehicle & it will get cranking voltage. I started my truck, no problem at all, and the meter said the voltage was 9.70 v. The minimum for a good battery is 9.60 v but a good battery should be higher typically 10v or better. Being that I bought my truck new in Sept 2017 I called the dealer & said I have a battery issue. they said bring it in and they'll check everything, battery, alternator, & starter. Well they found the battery was flaky & replaced it free of charge.
Here's my question, given that it was good today I'm wondering if it wasn't just low battery during it's power on boot cycle as mentioned in noupf's post above. As I stated my failure happened right after 2 starts a few minutes apart and having a marginal battery may have caused that. Has anyone else here had issues and found something similar to this?
