Avensis 1az fse

[Rcwk1]

Hey everyone 

Can anyone help with a 2004 1az fse t250 avensis workshop manual. Trying to get to the bottom of trc & vsc warning lights staying on. Had codes 1301, 1201, 1241. Cleared then and now just left with  1301- can communication error

I Googled your code as "P1301" and the response was "No.1 cylinder misfire". Try swapping the coil with another cylinder to see if it moves, and check the condition of the spark plugs. If the code changes then it is the coil pack. If it stay the same, then you have a wiring issue with to the coil pack from the ECU. Much harder to trace and fix.

This may not be correct but give it a try. I know you have a different meaning for the code which probably more accurate.
