Newbie here with a limp mode issue..
My son's car a 2016 Scion iM just went in to limp mode today , of course he is a ferry ride away so around 6 hours of travel time lol. Anyways he thinks it's in limp mode (wont go over 2,000 rpm) and the CEL is on.
He said he's been having problems with the battery, it's actually dead right now from starting it on the side of the road. The battery has died on him before if he listens to the radio for any length of time, ETC
Could a faulty battery cause the car to go into limp mode?
Thanks in advance.

I don't know but jump starting the car with cables crossed could. Your son needs a scan tool to diagnose the CEL. Might want to inspect the ETCS fuse in the engine bay. A crossed-cable jump start could have blown it.

Re: Limp mode.
Thanks for the response Fender , I dont think he has jumped it in awhile but I'll check it out. I'll just have to go throw my code reader on it well see what it say's The 3 year bumper to bumper warranty ran out on May 31 HaHa Ha that par for the course hey?

ECU and scanners won't work if battery is low. Absolutely certain test is to measure directly.
1. battery voltage with everything OFF
2. battery voltage during cranking
Those 2 numbers will tell tonne about what problems it may have.
