Step 6. Check the wiring harness between C-304 
key reminder switch connector terminal No.6 and 
C-220 ETACS-ECU connector terminal No.30.

•

Check the input line for open circuit.

Q: Is the check result normal?

YES : 

Go to Step 7.

NO : 

Repair the wiring harness.

Step 7. Retest the system.

Check that the key reminder switch signal is received 
normally.

Q: Is the check result normal?

YES : 

The trouble can be an intermittent 

malfunction (Refer to GROUP 00 

−

 How to 

Cope with Intermittent Malfunction 

P.00-6

).

NO : 

Replace the ETACS-ECU.

DIAGNOSTIC PROCEDURE

Step 1. Connector check: C-22 hazard warning 
lamp switch connector

Q: Is the check result normal?

YES : 

Go to Step 2.

NO : 

Repair the defective connector.

Step 2. Check the hazard warning lamp switch.
Refer to GROUP 54A 

−

 Hazard warning lamp switch 

P.54A-93

.

Q: Is the check result normal?

YES : 

Go to Step 3.

NO : 

Replace the hazard warning lamp switch.

Step 3. Measure the resistance at the C-22 hazard 
warning lamp switch connector.

(1) Disconnect the connector, and measure at the 

wiring harness side.

(2) Resistance between C-22 hazard warning lamp 

switch connector terminal No.2 and body earth

OK: 2 

Ω

 or less

Q: Is the check result normal?

YES : 

Go to Step 5.

NO : 

Go to Step 4.
