Since you have a B1318 - Battery Low, I would clear all the modules and start from scratch. Then periodically check for new errors that pop up. Especially since you say things are currently working fine.

Also, just because you have an error in one module doesn't mean that module is at fault. For example, I had numerous faults of modules on the high-speed CAN bus with the instrument cluster also going haywire. After much frustration, I narrowed it down to the brake pressure transducer being faulty and causing the ABS module to send garbage on the bus and confusing all connected modules. When you realize the ABS module is on one end of that HS CAN bus and the instrument cluster is on the other with CEM/ECM/TCM in between, it kind of makes sense.

Hey Charles
Thank you so much for your time and reply here

 

Hi,

I also been having similar “lots of odd codes” situations but different codes from yours. Some have been linked to minor wiring issues (seat wiring damage upsetting the airbag system for example) but majority seems to be linked to battery condition, specifically how the whole system “likes” coming up from a 10+mins battery disconnect. I’m looking next, into ground and battery connections or bad contacts. I get more odd codes when the battery is weak when it gets connected. Right now my battery (3years old) is around 12V and probably drops to 11V when connected. I’m waiting for a new one (lithium thing) and will report next week.

 

Hey Captain !
Thank you is good point let me see what can find ,

 

When I say “drop to 11V” that is temporary and it does come back to ~12V but the modules have come up with 11V or less for a period of time and that’s what I’m guessing can confuse the system and create errors that don’t clear. I would have thought they could just be cleared and not come back. When I had a stronger battery last fall the errors were less. This might feel like black magic and face of the moon behaviour but in the end it’s just a car with quirky electronics.
