Engine died while idle, code P0327,P1777,P1775

2005 VVT A/T

Anyone experienced anything like this? I started up my jimny to let it idle for a bit as I always do. Heard it shut off, like turning off the key. Went out restarted it, the dashboard lights where flickering a bit at first but runs fine.

Cheng engine light where lit, read out three codes P0327,P1777 and P1775. Cleared them and it all seems fine, drove to work and no new error codes.

Only two things is amiss, it ran rough, idle dropped after a few secs, but then smooths out shortly after. Does this from time to time

Brake warning light is lit, it came on when it died while idling, I`ll check the wiring and sensors later today


Did my ECM just have a brainfart?

So, I was thinking.. Might it just have been a short? What if It shorted out somewhere, causing a voltage drop, killing off sensor info and killing stopping the engine ?

There are only two things connected to the light in the dash, hand brake, and brake level. They are both ok

No idea I'm afraid. The P1775 and P1777 are not defined, but are usually auto transmission related, P0327 is a knock sensor.

Clear them and see if they come back.


It may have been caused by a heavy load at a low battery voltage I suppose.

Yeah, auto related

P1775- High speed CAN communication bus off (Transmission error)

P1777- TCM lost communication with ECM (Reception error)

I cleared them right after it happened, have driven 1600km since it happened, still have the brake warning light lit on the dash. its brighter when I apply hand brake. A/T works normally

I need to chase the wiring in the circuit, but have not had the time or motivation, other than doing the easiest checks
