INSPECTION PROCEDURE

PROCEDURE

1. CHECK REAR WIPER OPERATION
(a) Turn the ignition switch to ON.
(b) Turn the rear wiper switch on.
(c) Turn the rear wiper switch off.
(d) Check that the rear wiper stops at the retract position when the rear wiper switch is turned off.
OK:
The rear wiper arm returns to the correct position.

NG -- REPAIR OR REPLACE REAR WIPER MOTOR ASSEMBLY
OK -- Continue to next step.

2. READ VALUE USING TECHSTREAM (WIPER RETRACTED POSITION)
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON.
(c) Turn the Techstream on.
(d) Enter the following menus: Body Electrical / Back Door P/W / Data List / Wiper Retracted position
(e) According to the display on the Techstream, read the Data List.

Back Door P/W





OK:
The Techstream display changes normally when rear wiper motor is operated.

NG -- CHECK HARNESS AND CONNECTOR (BACK DOOR ECU - REAR WIPER MOTOR ASSEMBLY)
OK -- Continue to next step.

3. PERFORM ACTIVE TEST USING TECHSTREAM (BACK DOOR POWER WINDOW)
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON.
(c) Turn the Techstream on.
(d) Enter the following menus: Body Electrical / Back Door P/W / Active Test / Back Door Power Window
(e) Check that the back door power window regulator motor move the window UP/DOWN.

Standard Resistance:





(c) Reinstall the back door power window regulator switch assembly.

NG -- REPLACE BACK DOOR POWER WINDOW REGULATOR SWITCH ASSEMBLY
OK -- Continue to next step.

5. CHECK HARNESS AND CONNECTOR (BACK DOOR POWER WINDOW REGULATOR SWITCH - BODY GROUND)





(a) Disconnect the H9 back door power window regulator switch assembly connector.
(b) Measure the resistance according to the value(s) in the table below.

Standard Resistance:





(c) Reconnect the back door power window regulator switch assembly connector.

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- REPAIR OR REPLACE HARNESS OR CONNECTOR (BACK DOOR ECU - BACK DOOR P/W REGULATOR SWITCH)
6. INSPECT BACK DOOR POWER WINDOW REGULATOR MOTOR ASSEMBLY





(a) Remove the back door regulator motor assembly Disassembly.
(b) Apply battery voltage between the connector terminals and check that the motor gear rotates smoothly.

NOTE: Do not apply battery voltage to any terminals except terminals 1 and 2.

Standard:





(c) Reinstall the back door regulator motor assembly.

NG -- REPLACE BACK DOOR POWER WINDOW REGULATOR MOTOR ASSEMBLY
OK -- Continue to next step.

7. CHECK HARNESS AND CONNECTOR (BACK DOOR ECU - BACK DOOR POWER WINDOW MOTOR)





(a) Disconnect the V3 back door ECU connector.
(b) Disconnect the V4 back door regulator motor assembly connector.
(c) Measure the resistance according to the value(s) in the table below.

Standard Resistance:





(d) Reconnect the back door ECU connector.
(e) Reconnect the back door regulator motor assembly connector.

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- REPLACE BACK DOOR ECU
8. CHECK HARNESS AND CONNECTOR (BACK DOOR ECU - REAR WIPER MOTOR ASSEMBLY)





(a) Disconnect the V3 back door ECU connector.
(b) Disconnect the V10 rear wiper motor assembly connector.
(c) Measure the resistance according to the value(s) in the table below.

Standard Resistance:





(d) Reconnect the rear wiper motor assembly connector.
(e) Reconnect the back door ECU connector.

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- REPLACE REAR WIPER MOTOR ASSEMBLY
