Step 2. Resistance measurement at the B-135
column switch connector.
(1) Disconnect the connector, and measure at the
column switch side.
(2) Resistance between B-135 column switch
connector terminal No.6 and body earth
OK: The resistance should rise from 0 to
1 k
Ω when the windshield intermittent
wiper volume is rotated from "Fast" to
"Slow".
Q: Is the check result normal?
YES :
Go to Step 3.
NO :
Replace the column switch.
Step 3. Connector check: B-133 ETACS-ECU
connector.
Q: Is the check result normal?
YES :
Go to Step 4.
NO :
Repair the defective connector.
Step 4. Check the wiring harness between B-135
column switch connector terminal No.6 to B-133
ETACS-ECU connector terminal No.73.
• Check the input line for open circuit.
Q: Is the check result normal?
YES :
Go to Step 5.
NO :
Repair the wiring harness.
Step 5. ETACS ANALOG data by using the SWS
monitor.
Check the input signal from the windshield intermit-
tent wiper volume.
• Ignition switch: ACC
• Wiper switch: INT
OK: The display will be changed as the inter-
mittent wiper volume is rotated.
Q: Is the check result normal?
YES :
The trouble can be an intermittent
malfunction (Refer to GROUP 00
− How to
use Troubleshooting/inspection Service
Points
− How to Cope with Intermittent
).
NO :
Replace the ETACS-ECU.

54C-213
Inspection Procedure N-7: The key reminder switch signal is not received.
CAUTION
Whenever the ECU is replaced, ensure that the
input signal circuit is normal.
COMMENTS ON TROUBLE SYMPTOM
Input signal from the key reminder switch is used to
operate the functions below. If the signal is abnormal,
these functions will not work normally.
• Keyless entry system
• Ignition key cylinder illumination lamp
• Room lamp
POSSIBLE CAUSES
• Malfunction of the key reminder switch
• Malfunction of the ETACS-ECU
• Damaged harness wires and connectors
DIAGNOSIS PROCEDURE
Step 1. Connector check: B-140 key reminder
switch connector
Q: Is the check result normal?
YES :
Go to Step 2.
NO :
Repair the defective connector.

Step 2. Check the key reminder switch.
Refer to GROUP 54A
− Ignition switch
.
Q: Is the check result normal?
YES :
Go to Step 3.
NO :
Replace the key reminder switch.
Step 3. Resistance measurement at the B-140 key
reminder switch connector.
(1) Disconnect the connector, and measure at the
wiring harness side.
(2) Resistance between B-140 key reminder switch
connector terminal No.4 and body earth
OK: Continuity exists (2
Ω or less)
Q: Is the check result normal?
YES :
Go to Step 5.
NO :
Go to Step 4.
Step 4. Check the wiring harness between B-140
key reminder switch connector terminal No.4 to
the body earth.
NOTE:
Prior to the wiring harness inspection, check joint
connector B-25, and repair if necessary.
• Check the earth wires for open circuit.
Q: Is the check result normal?
YES :
The trouble can be an intermittent
malfunction (Refer to GROUP 00
− How to
use Troubleshooting/inspection Service
Points
− How to Cope with Intermittent
).
NO :
Repair the wiring harness.
Step 5. Connector check: B-133 ETACS-ECU
connector
Q: Is the check result normal?
YES :
Go to Step 6.
NO :
Repair the defective connector.
