basicly we gave a immobiliser unit to this guy and he replaced damaged transistors and connected key ring with immo-ecu and returned ready do go circuity.. unfortunately he didnt share any diagrams

Hi! After solving immobiliser problem we have next one to take care .. car starts & drive but after few minutes it losses its power and dies, then wont start at all. When its gets cooler start again for some time then dies again and wont start until its cold. Patient is IS200 '99 with 1uz-fe...

OK, the car is running (not completely like I would like to but thats topic for another tread) cause was damaged immobiliser unit luckily we found some toyota_guru who had those diagrams and managed to fix immo problem

immobiliser circuit is damaged now so we have to skip it ;) another weird thing - we get 3 DTCs: 27 (O2 Sensor - not connected) 29 (O2 Sensor - not connected) 99!!! what is this?? we are looking for ecu without immo ;)

coil is on the way so we will try to fire it up with this ecu.. unfortunately those 5 wires are messed up :P it probably ends up by chasing routes in amplifier ;) lack of immobiliser wiring diagrams is killing me.. few days of searching and nothing

yes, engine is 1uz-fe from ucf20

here we have Immobilizer ECU maybe LS400 '97+ security wiring will match? can someone took a picture of 5-wire white plug going into key amplifier? we messed up with it without taking notes ;)

100% sure its oem system ;) coil is bought cuz "immobilizer magician" just informed that his chip wont work for this ecu ;)

we have a key and immobilizer ecu, but lost somewhere amplifier with key coil :/ theres one in is200, even 5-wire connector match but signals are different (thats what I assumed after chasing routes of immobilizer ecu) in donor car diagnostic plug inside was like obd1 car (round), second under...

its usa ls400.. I have a box but didnt took a picture of it (I'll get one today) I've checked trouble codes only by shortwiring pins in diagnostic plug (finally only 27 and 29 poped up cuz sub-lambda sensord are not connected)

coil and spark is OK, fuel is well burned and nothing is going to the exhoust.. it looks like after engine starts injectors stops and it dies :/ I have only photo of the inside of immo unit ecu

maybe.. but I have a Immobilizer ECU connected with ECM ;) probably because of that engine starts and die after 2-3sec.. sometimes its idling for some time but dies when throttle is pushed

hi! I'm in the middle of 1uzfe from ls400 '96 to is200 swap and have a problem with proper connection of immobilizer ecu - can't find any diagrams or so :/ no problem with is200 diagram but nothing to ls400 thanks
