STEP 3. Check the driver's side door switch.

Remove the driver's side door switch. Refer to GROUP 42, 
Door 

P.42-132

.

Q: Is the driver's side door switch in good condition?

YES : Go to Step 4.
NO :  Replace it. Check that the malfunction is eliminated.

STEP 4. Check the driver's side door switch ground circuit.

Measure the resistance between the driver's side door switch 
body (metal section) and ground.

• The measured value should be 2 ohms or less.

Q: Does the measured resistance value correspond with 

this range?
YES : Go to Step 5.
NO :  Repair the harness wire or connector. Then check 

that the malfunction is eliminated.

STEP 5. Check driver's side door switch connector E-33 
input circuit.

(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 6.

STEP 6. Check driver's side door switch connector E-33 
for loose, corroded or damaged terminals, or terminals 
pushed back in the connector.

Q: Is driver's side door switch connector E-33 damaged?

YES : Repair or replace it. Refer to GROUP 00E, Harness 

Connector Inspection 

P.00E-2

. The tachometer 

should work normally.

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 and ETACS connector D-11 in good 
condition?
YES : Go to Step 8.
NO :  Repair them. Then check that the malfunction is 

eliminated.

STEP 8. Check for continuity of the key reminder switch.

(1) Remove the driver's side under cover. Refer to 

P.52A-37

.

(2) Remove the column covers, lower and upper.
(3) Disconnect wiring connector D-16 from the key reminder 

switch and measure at the key reminder switch side.

(4) Measure the resistance between terminal numbers 4 and 6.

Q: Does the measured resistance value correspond with 

this range?
YES : Go to Step 9.
NO :  Replace the key reminder switch. Then check that the 

malfunction is eliminated.

STEP 9. Check the input signal from the key reminder 
switch.

Check that the tone alarm stops sounding when terminal num-
ber 6 is grounded.
Q: Does the tone alarm stop sounding?

YES : Go to Step 10.
NO :  Go to Step 12.
