07 yaris 89780-52070 immo problem

[darrenhyland]

I have an 07 toyota yaris with immobox number 89780-52070. It has an immo problem..... it starts for a second and stops. The immo light never comes on. I bridged 4 and 13 with no result. Both keys ok and wiring checked. No faults in the immo system but B2799 in the ecu (bosch) that wont clear. I reset the immobox using K518 with no result. All power and earths ok. Any ideas?

you only need to do the ecu free eeprom

Can you explain nono1.....thanks.

[nono1]

there is a free code eeprom ic that you will use to replace that eeprom of the ECU it number is ''4558d''
if you can get that ic then replace it with the ecu's own then the car will start..
or u change the ECU of the car after you change it then you bridge 4 and 13
