been detected in ECM—
*: When NATS detects trouble, the security indicator lights up while ignition key is in the “ON” position.
*: When the vehicle is equipped with a dongle unit (RHD models for Europe), the security indicator blinks 6 times just after the ignition
switch is turned to ON. Then the security indicator lights up while the ignition key is in the “ON” position.
