hi there. does someone knows what the following fault codes mean on a toyota avanza 1.5 vvti. around 2005 model. under immobilizer is B2788....under ecu is P1601 eeprom error injector correction value DPNR thermal degradation record. these faults does clear , but after start they re appear. fault codes were scanned using autoboss v30. the vehicle does not start at all. many thanks in advance.

P1601 is an internal control module error which may be wiring, transmission or transmission control module related
P1601 - ECM/TCM Serial Communication Err
p1601 stands for engine control module(ecm)transmission control unit(tcm)-serial peripheral comminication

i would just like to know if this vehicle has a immo problem looking at the fault codes discribed above. if not then im convinced it has a wiring problem. thanks. cheers.

P1601 eeprom error injector correction value DPNR thermal degradation record car will not start got workshop manual and it explains must replace ECU + Exhaust mainfold once this DTC is present :-(

what is security light status is it going off when ing on .

apparently the plate on the cranckshaft were fitted incorrectly. the speed sensor were picking the tdc mark up at the wrong time. once the ring were fitted correctly, the vehicle started. but it had some other issues aswell. but it started. thanks.

You need to write virgin files on both ecu and immo box
