Thanks for that @ColinBarber. Definitely the cheapest I have come across 👍🏻👍🏻

@diabolik I’m only on 37k miles. Another question for guys here - does the mark 3 Prius use the same 12v battery as the CT? Quotes from Toyota are much cheaper than Lexus for the same battery, as you’d expect 😅

Thanks 200h. I think that the battery is probably on its way out so I’m gonna replace it ASAP. It’s 8 years old as far as I can tell. Thought it might have been something more serious, but from what I gather the 12v battery can cause lots of weird warning messages

Okay I’ll try load testing it and see what happens. Thanks for your help lads, greatly appreciated! 👍🏻

I just took note of the warning messages that came up on the dash. I read something online about the 12v battery going bad being the cause of the ‘P Lock Malfunction’ message. I then disconnected the 12v battery in order to clear the ECU memory which it did. Car seems to be running fine but I’m trying to get to the root cause of it, just in case it might be something more serious! Just tested the voltage with a multimeter and it read 12.55, with no load

Hi Folks I just recently bought a 2013 Lexus CT200h. I went to start the car yesterday and got The ‘P lock malfunction’ warning followed by ‘Check Hybrid System’. The car actually started and drove fine. I disconnected the 12v battery to clear the codes and everything seems to be ok since. After doing a bit of reading online some people have mentioned that when the 12v battery is on its way out you can get these Warning lights. Can anyone throw some light on this? The battery as far as I can tell is the original so it’s close to 8 years old. Main dealer here in Ireland is looking to charge 140e to run a diagnostic check! Thanks lads!
