Circuit Description
Operation (ON/OFF) of ESP® warning lamp is controlled by ESP® control module through lamp driver module in
combination meter.
If ESP® system is in good condition, ESP® control module turns ESP® warning lamp ON at the ignition switch ON,
keeps it ON for 2 seconds and then turns it OFF. If an abnormality in the system is detected, ESP® warning lamp is
turned ON continuously by ESP® control module. Also, it is turned ON continuously by lamp driver module when the
connector of ESP® control module is disconnected.
