Disconnect the L16 display connector.

Measure the resistance and voltage of the wire harness side connector.

SYMBOLS (TERMINAL NO.) AND DESCRIPTION

Symbols (Terminal No.)	Wiring Color	Terminal Description	Condition	Specified Condition
GND (L16-12) - Body ground	W-B - Body ground	Ground	Always	Below 1 V
ACC (L16-15) - GND (L16-12)	GR - W-B	Ignition (ACC)	Ignition switch ACC	10 to 14 V
+B (L16-16) - GND (L16-12)	L - W-B	Battery	Always	10 to 14 V

If the result is not as specified, there may be a malfunction on the wire harness side.

Reconnect the L16 display connector.
Measure the voltage of the connectors.
