Toyota Corolla (E120): Inspection
1. Windshield wiper switch assy
- Continuity check
- check the continuity of each terminal of the connector.
Front wiper switch
Standard:
Front washer switch
Standard:
- W/o intermittent time adjust: intermittent operation check
- connect the voltmeter (+) terminal to terminal 7 (+1) of the connector, the voltmeter (–) terminal to terminal 5 (ew) of the connector.
- Connect the battery (+) to terminal 8 (+b) of the connector, the battery (–) to terminal 5 (ew) and 6 (+s) of the connector.
- Turn the wiper switch to the int position.
- Connect the battery (+) to terminal 6 (+s) of the connector for 5 seconds.
- Connect the battery (–) to terminal 6 (+s) of the connector.
Operate the intermittent wiper relay and check voltage between terminal 7 (+1) and terminal 5 (ew).
- W/ intermittent time adjust: intermittent operation check
- connect the voltmeter (+) terminal to terminal 7 (+1) of the connector, the voltmeter (–) terminal to terminal 5 (ew) of the connector.
- Connect the battery (+) to terminal 8 (+b) of the connector, the battery (–) to terminal 5 (ew) and 6 (+s) of the connector.
- Turn the wiper switch to the int position.
- Connect the battery (+) to terminal 6 (+s) of the connector for 5 seconds.
- Connect the battery (–) to terminal 6 (+s) of the connector.
Operate the intermittent wiper relay and check voltage between terminal 7 (+1) and terminal 5 (ew).
- Operation check (washer switch)
- turn the wiper switch to the off position.
- Connect the battery (+) to terminal 8 (+b) of the connector, the battery (–) to terminal 6 (+s) and 5 (ew) of the connecter.
- Connect the voltmeter (+) terminal to terminal 7 (+1)
of the connector, the voltmeter (–) terminal to terminal
5 (ew) of the connector. Turn the washer switch
to on and off and check voltage between terminal
7 (+1) and terminal 5 (ew).
Standard: see the illustration.
2. Windshield wiper motor assy
- Lo operation check
- connect the battery (+) to terminal 1 (+1) of the connector, the battery (–) to terminal 5 (e) of the connector, and check that the motor operates at low speed (lo).
- hi operation check
- connect the battery (+) to terminal 4 (+2) of the connector, the battery (–) to terminal 5 (e) of the connector, and check that the motor operates at high speed (hi).
- automatic stop operation check
- connect the battery (+) to terminal 1 (+1) of the connector,
the battery (–) to terminal 5 (e) of the connector.
With the motor being rotated at low speed (lo), disconnect terminal 1 (+1) to stop the wiper motor operation at any position except the automatic stop position.
- Connect terminal 1 (+1) and 3 (s), and the battery
(+) to terminal 2 (b) to restart the motor operation at
low speed.

Circuit description
A flat type knock sensor (non–resonant type) has the structure that can
detect the vibration in a wider band
of frequency from about 6 khz to 15 khz and has the following features.
Knock sensors are fitted on the cylinder block to detect the engine knocking.
The sensor contains a piezoele ...

Inspection
1. Inspect starter assy
Notice:
these tests must be performed within 3 to 5 seconds to
prevent burnout of the coil.
perform the pull–in test.
Remove the nut, then disconnect the lead wire from
terminal c.
Connect the battery to the starter repai ...
Indicators
The indicators inform the driver of the operating state of the vehicle’s various
systems.
*1: Vehicles without a smart key system:
These lights turn on when the engine switch is turned to the “ON” position to indicate
that a system check is being performed. They will turn off after the ...
