9-22 ELECTRICAL SYSTEM
Operation
When the ignition switch is turned ON with the engine stop switch in ON, the immobi-antenna and ECM are
powered ON.
The ECM transmits a signal to the transponder through the immobi-antenna in order to make comparison
between the key ID and ECM ID.
With the signal received, the transponder transmits the key ID signal to ECM so that ECM can make com-
parison with its own ID, and if it matches, the engine is made ready to start.
 Immobi-antenna
Also, when the ignition switch is turned ON, the indicator light
flashes as many as the number of IDs registered in ECM. There-
after, if the IDs are in agreement, the indicator light turns on for
two seconds to notify of completion in successful communica-
tion.
If the indicator light (LED) flashes fast, it notifies of communica-
tion error or disagreement of ID.
NOTE:
If the indicator light  flashes fast, turn the ignition switch OFF
then ON to make judgment again as there is possible misjudg-
ment due to environmental radio interference.
When the battery performance is lowered in winter
(low temperature), the system may at times makes a
re-judgment at the time of beginning the starter motor
operation. In this case, the indicator light operation
starts immediately after the starter operation.
NOTE:
In the case that the LED flashes fast, remains lit or unlit, the probable cause of such a failure may be due to
abnormal condition in the key, key cylinder, wiring harness or ECM. (If such a failure exists, contact your dis-
tributor or dealer.)
