I have rav4 2002, wont start, code B2796 No communication in immobiliser system, but these rav4 dont have immo system.How can I fix

**pandokrator** · 26th February, 2014, 09:41 AM

hi friend,
are you sure 100% for that car don't use immobox ?
use only remote control for unlock locks and immo or have you 4C TP key?
if exist ,try to follow the antenna from ignition lock.
also look if car have extra alarm system (too many probs in the past with extra alarm shits & bad wiring work)

if is immo prob and car have not use immo box then read your eeprom and upload here for virginize (keys are stored ONLY on e2p location on this Denso NOT on flash)
OR just use my uploaded virgin e2p dump for re-program keys on car.
best regards

Does your car used toyota remote before it start?and now the remote not work or lost.

Check the wires of coils if aren't tight together cause of gasket heating,if so seperate them.

If not,post here 25080 dump in ecu to repair.

Remove EEPROM and read as 16 bit.
On these lines

Line 100 thru line 1F0 put to 0 (ZERO)
Then reinstall EEPROM
I do not know if this will fix IMMO or not.
I use this after ECU repair procedure to clear transmission learned adaptives.
Hope this is what you are looking for.

Hello,
I have a 2002 toyota rav4 that is giving some shifting proble second to third. I know it is not the transmission. Could you please share the repair procedure so I can repair my wife's car. Thanks in advance.
