I recently has problems with my XYZ switch.
I was getting the dreaded M & S flashing lights.
So, I bought a used one on eBay for $150 and it worked for about a week.
It started to do it again this week.
I had the battery and alternator checked and they are both good.
I am also occasionally getting the P0741 error code.
Could these two things be related?
I'm going to replace the transmission fluid and filter this weekend to see if that helps.
Any thoughts?

 

What is P0471?

 

Who checked the battery? I would check the actual positive and negative cables and the connections to the battery terminals. Clean the terminals good and the battery posts. Make sure they have a tight connection. Also check your ground on the shock tower or whatever chassis ground you have setup. If your running the original battery terminals this could be an issue not being tight enough. I've been here before and had the M+S flashing lights. Upgrade the "Big 3" with new cables. I have no idea what code you are referencing so can't comment.

 

P0741 is a transmission code related to torque converter.

i second what has already been said. check all ground connections and the positive battery cable.

i had the flashing M+S due to loose battery cable clamps. rebuilt them with "military" style clamps and haven't had an issue since.

 

It's P0741

If your voltage and grounds are all okay, check if AC condensate is dripping onto the XYZ switch.

I've dealt with M&S lights several times - first it was a bad ground leading to grounding of the parking brake cable (rubber covering melted into the interior cable/spring requiring replacement).

Then twice have had batteries fail after 1 yr of unpaved roads.

Most recently, I was clearing codes via OBD2 Torque App every 2-3 minutes to get the car out of limp-mode. The solution was to re-route the driver's AC condensate with some 1/2" hose shoved into the rubber opening above the transmission housing (zip-tie to the rigid cooler line).

I also have the same battery terminal connectors and no issues with them - make sure the battery posts are clean and have vaseline.
