2. CHECK THE INTERMITTENT OPERATION (INSPECTION OF THE WIPER SWITCH ALONE)

Intermittent operation inspection (Except for KA model)

1. Connect the voltmeter between switch terminal 7 (+) and 2 (−).

2. Connect the battery between switch terminal 17 (+) and 2 (−).

3. Turn the front wiper switch to INT.

4. Connect the battery positive terminal to the switch terminal 16 for 5 seconds.

5. Connect the battery negative terminal to the switch terminal 16 and measure the voltage between switch terminal 7 and 2 when performing the intermittent operation.

6. Perform step 1) to 5) when intermittent control switch is in MIN or MAX, and check that the operation is specified below.

Terminals

No. 7 — No. 2:

(1)

Approx. 12 V

(2)

Approx. 0 V

(3)

Connect the battery negative terminal to the switch terminal 16.

(4)

Intermittent stationary time

Specification for intermittent stationary time

MIN: Approx. 2 seconds

MAX: Approx. 16±6 seconds

7. If operation is not as specified, replace the switch.

Intermittent operation inspection (KA model)

1. Connect the voltmeter between switch terminal 3 (+) and 8 (−).

2. Connect the battery between switch terminal 11 (+) and 8 (−).

3. Turn the front wiper switch to INT.

4. Connect the battery positive terminal to the switch terminal 12 for 5 seconds.

5. Connect the battery negative terminal to the switch terminal 12 and measure the voltage between switch terminal 3 and 8 when performing the intermittent operation.

6. Perform step 1) to 5) when intermittent control switch is in MIN or MAX, and check that the operation is specified below.

Terminals

No. 3 — No. 8:

(1)

Approx. 12 V

(2)

Approx. 0 V

(3)

Connect the battery negative terminal to the switch terminal 12.

(4)

Intermittent stationary time

Specification for intermittent stationary time

MIN: Approx. 2 seconds

MAX: Approx. 16±6 seconds

7. If operation is not as specified, replace the switch.
