E-33.

(1) Disconnect the driver's side door switch connector E-33 and 

the harness side.

(2) Measure the voltage between terminal 2 and ground.

• The measured value should be approximately 5 volts.

Q: Does the measured voltage correspond with this range?

YES : There is no action to be taken.
NO :  Go to Step 7.

NOTE: After inspecting junction block connector D-14 and 
intermediate connector E-42, inspect the wire. If junction block 
connector D-14 and intermediate connector E-42 are dam-
aged, repair or replace them. Refer to GROUP 00E, Harness 
Connector Inspection 

P.00E-2

.

Q: Are the harness wires between driver's side door switch 

connector E-33 (terminal No.2) and ETACS connector 
D-11 (terminal No.9) in good condition?
YES : Go to Step 8.
NO :  Repair them. Then check that the malfunction is 

eliminated.

STEP 8. Check the ignition key hole illumination light 
input.

P.52A-37

).

(2) Remove the lower and upper column covers (Refer to 

P.52A-37

).

(3) Disconnect wiring connector D-16 from the key reminder 

switch and measure at the switch side.

(4) Connect a vehicle battery as shown, and then check the 

ignition key hole illumination light illuminates.

Q: Does the situation key hole illumination light 

illuminate?

STEP 9. Check the power supply for the ignition key hole 
illumination light.

(1) Disconnect the key reminder switch connector D-16 and 

measure at the harness side.

(2) Measure the voltage between terminal 1 and ground.

(battery positive voltage).

Q: Is the measured voltage within this specified range?

YES : Go to Step 11.
NO :  Go to Step 10.

STEP 10. Check connector D-16 at the key reminder switch 
for damage.

Q: Is key reminder switch connector D-16 in good 

condition?
YES : Go to Step 11.
NO :  Replace it. Then check that the malfunction is 

eliminated.

STEP 11. Check the harness wires between fusible link 
number 8 and key reminder switch connector D-16
