SYSTEM TESTS
FRONT WIPER/WASHER SWITCH INTERMITTENT OPERATION
Except Celica & RAV4
1. Disconnect combination switch connector. Turn wiper/washer switch to INT position. Rotate intermittent
time control to FAST position. Connect fused jumper between battery voltage and terminal No. 16.
Connect jumper wire between ground and terminal No. 2. See Fig. 6
. Connect DVOM positive lead to
terminal No. 7 and negative lead to terminal No. 2. For Avalon, go to next step. For Camry, Camry
Solara, Sienna, Tacoma, Tundra and 4Runner, go to step 3 . For Corolla, Land Cruiser and Lexus LX470,

2. DVOM should indicate battery voltage. With DVOM connected, momentarily connect terminals No. 16
and 17 with a fused jumper. With jumper still connected to terminal No. 16, move jumper from terminal
No. 17 to terminal No. 2. DVOM reading should change from zero volts to battery voltage in about 3
seconds. If operation is not as specified, replace wiper/washer switch. See FRONT WIPER SWITCH

under REMOVAL & INSTALLATION.
3. DVOM should indicate battery voltage. Monitor DVOM reading while rotating intermittent time control
from SLOW to FAST positions. In SLOW position, voltage will change from zero to battery voltage in
10-15 seconds. In FAST position, voltage will change from zero to battery voltage in 1-3 seconds. If
operation is not as specified, replace wiper/washer switch. See FRONT WIPER SWITCH
under
REMOVAL & INSTALLATION.
4. DVOM should indicate battery voltage. With DVOM connected, momentarily connect terminals No. 16
and 17 with a fused jumper. With jumper still connected to terminal No. 16, move jumper from terminal
No. 17 to terminal No. 2. See Fig. 6
. Monitor DVOM reading while rotating intermittent time control
from SLOW to FAST positions. In SLOW position, voltage will change from zero to battery voltage
within 10-15 seconds (6-16 seconds on Land Cruiser and Lexus LX470). In FAST position, voltage will
change from zero to battery voltage in 1-3 seconds. If operation is not as specified, replace wiper/washer
switch. See FRONT WIPER SWITCH
under REMOVAL & INSTALLATION.
Celica & RAV4
1. Disconnect combination switch connector. Turn wiper/washer switch to INT position. Rotate intermittent
time control to FAST position. Connect fused jumper between battery voltage and terminal No. 17.

. Connect
DVOM positive lead to terminal No. 7 and negative lead to terminal No. 2.
2. Depress washer switch and monitor DVOM voltage readings. On Camry, Camry Solara, Sienna, Tacoma
and Tundra, readings should change from zero volts to battery voltage within one second of depressing
washer switch. After switch is released, readings should change from battery voltage to zero volts in
about 25 seconds (3 seconds on Tacoma, Tundra and 4Runner). If readings are not as specified, replace
wiper/washer switch. See FRONT WIPER SWITCH
under REMOVAL & INSTALLATION.
