Check code 04

Check code 04		TNS ON/OFF signal
STEP	INSPECTION CONDITION	DISPLAY	ACTION
1	Turn the light switch to the ON position.		Go to the next step.
			Verify that the voltage of multi information display terminal 1B is B+. • If the voltage is as specified, replace the multi information display. • If the voltage is not as specified, inspect the following parts: ― TNS relay ― Light switch ― BCM ― Wiring harness (Light switch—BCM—TNS relay—Multi information display)
2	Turn the light switch off.		Verify that the voltage of the multi information display terminal 1B is 1.0 V or less. • If the voltage is as specified, replace the multi information display. • If the voltage is not as specified, inspect the following parts: ― TNS relay ― Light switch ― BCM ― Wiring harness (Light switch—BCM—TNS relay—Multi information display)
			Input signal to the multi information display is normal.

Check code 06

Check code 06		Ignition switch ON/OFF signal
STEP	INSPECTION CONDITION	DISPLAY	ACTION
1	Turn the ignition switch to the ON position.		Go to the next step.
			Verify that the voltage of multi information display terminal 1E is B+. • If the voltage is as specified, replace the multi information display. • If the voltage is not as specified, inspect the following parts: ― Ignition switch ― Wiring harness (Battery—Ignition switch—Multi information display)
2	Turn the ignition switch to the ACC position.		Verify that the voltage of the multi information display terminal 1E is 1.0 V or less. • If the voltage is as specified, replace the information display or multi information display. • If the voltage is not as specified, inspect the following parts: ― Ignition switch ― Wiring harness (Battery—Ignition switch—Multi information display)
			Input signal to the multi information display is normal.
