Check code 04

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