The intermittent wiper interval is calculated in accordance with the input signal from the windshield intermittent wiper volume. If this signal is abnormal, the wiper interval can not be adjusted.POSSIBLE CAUSES
- Malfunction of the column switch
- Malfunction of the ETACS-ECU
- Damaged harness wires and connectors
DIAGNOSIS PROCEDURE
Step 2. Measure the resistance at the C-310 column switch connector.
- Disconnect the connector, and measure at the column switch side.
- Resistance between C-310 column switch connector terminal No.6 and body earth
OK: The resistance should rise from 0 to 1 kΩ
when the windshield intermittent wiper volume is rotated from "Fast" to "Slow".
Q: Is the check result normal?
YES:
Go to Step 3
