9W-8 IMMOBILIZER SYSTEM
DefectsPossible cause Remedy
No communication with
transponder1. Defective wiring harness
- Power supply/Open/short of ground
- Open/short of signal terminal or
mis-conneting(between ECU
terminal No. 13 and 14)1. Connect/replace the wire correctly.
2.1 Replace the transponder
2.2 Immobilizer programming 2. Damaged transponder
3. Replace the antenna3. Defective antenna
4.1 Replace the ECU
4.2 Replace all transponder of the keys
4.3 Immobilizer programming 4. Defective ECU
No immobilizer
programming
(Components and
wiring harnesses are
normal but codes in
ECU and transponders
are not registered
normally)1. Replace the transponders and ECU
with new
; Immobilizer programming is not
performed1. Perform immobilizer programming
2. Replace transponders only(new)
; Immobilizer programming is not
performed2. Perform immobilizer programming
3. Replace ECU only(new) 3.1 Replace the transponders with new
3.2 Perform immobilizer programming
4. Replace the transponder only
; Programmed for other ECU4.1 Replace the transponders with new
4.2 Perform immobilizer programming
5. Re-programming is not performed
after clearing transponder code stored
in ECU that normally used system5. Immobilizer programming
Notice
1. Application of ex-programmed transponder into other ECUs.
; In this case, it can not be removed for the settled “lock bit” in transponder even though you perform immobilizer
problem normally. Moreover it is impossible to start engine, so replace the transponder with new and perform
immobilizer programming.
