Problems updating form ZA1JA01G to ZA1JD00G ROM - fixed disable U0155 code in rom


Problem now fixed by disabling CEL code U0155 in rom you will need the latesd definition files as the option was not availablein original definitions for romraider or ecuflash.


Ok My car was originally ZA1JA01G (2013) all ok no problems, flashed the latest STOCK ZA1JD00G rom absolutely stock nothing changed. Flashed with Tactrix/Ecuflash. (I also have OFT but it will not jump calid's without a bit of messing around)

Got CEL light Code U0155 Can Buss communications erro,r thought no worries get that occasionally after flash or when plugging in logging device or OFT. Tried to clear code no go comes straight back.

Car Starts ok idles runs ok up to about 4000 rpm then no power (this is on completely stock ZA1JD00G rom. Stop reset clear code comes straight back. Logged and everthing looks pretty normal , suspect its in limp home mode due can- buss error.

Flash back stock ZA1JA01G rom all sweet no codes no light car runs fine no can-buss problems.

Appears something has changed with new 2015 cars either software in another computer or some hardware that is not installed in earlier cars and ECU code is not talking to something correctly on can-buss.

anyone else flashed a D00G rom to an earlier model car with success ?

@Shiv@Openflash @Td-d any ideas
