[smart2010]

Hi,

Does anyone knows the couse of the problem when the MIL light of the infiniti I30 2001 does not light up when i removed any sensor cable like engine cam shaft sensor ...etc and also the ECM does not communicate with OBDII scan tool to know exactly the problem.I had before an Air bag alarm when i did a maintenace of AC without removing the batt terminal then i reseted manually through ignition switch ON,OFF procedures.I really do not know wheather this way will disable the MIL light and couse not to light up. Please help

If you removed the connection and it didn't recognize it as a hard fault. If th run conditions to set that light werne't met, the light won't activate.

If you'd like people to actually respond to your question, try writing in comprehensible English.

Since I'm guessing that English isn't your first language, I'll give this a shot. If the check engine light isn't illuminating and you aren't having any connectivity to a reader, it may be a bad computer. My first question would be is the light coming on for a few seconds when you first start the car? Also, the airbag light reset would have no effect on the check engine light.
