TIRE PRESSURE WARNING LAMP CIRCUIT
CIRCUIT DESCRIPTION
When the tire pressure decreases, the skid control ECU sends the communication signal to the combination meter assembly through the ECM, and it
illuminates the tire pressure warning lamp on the combination meter assembly.
The tire pressure warning lamp also comes on when the signal for the tire pressure warning lamp cuts off.
HINT: Refer to the "TIRE PRESSURE WARNING LAMP CHART" section in the "PRE-CHECK" for the tire pressure warning lamp.
