03-9 7010-06 ECU Immobilizer Indicator and Warning Lamp ▶ This indicator comes on when the ignition key is communicating with the engine control unit (during engine starting) and goes out after starting the engine. When turning the ignition key to ON position, the ECU transmits the challenge message to the immobilizer unit to verify whether the key is valid. (1) Only when the two signals are identical, it recognizes the key as the authorized one and transmits the positive message to the ECU. The ECU allows the engine to be started. (6) (7) Do not drop or shock to the transponder in the key as it may be damaged. With a damaged transponder, the engine cannot be started. When you erase the code or register an extra key, let the owner attend on the site. In any case, the immobilizer system cannot be removed from the vehicle. If you attempt to remove it and damage the system, starting will be impossible, so never attempt to remove, damage or modify it. The remote engine starter cannot be installed on the vehicle equipped with the immobilizer system. - - - - - Lamp ON: in communication Blinking twice for one second: immobilizer system failure Blinking once for two seconds: immobilizer unit is not coded The immobilizer indicator does not come on if the communication time between immobilizer key and ECU is too short.
