INSPECTION PROCEDURE

NOTICE:
Inspect the fuses for circuits related to this system before performing the following inspection procedure.

HINT
Since the power window control system has functions that use LIN communication, first confirm that there is no malfunction in the communication system by inspecting the LIN communication functions in accordance with the "How to Proceed with Troubleshooting" procedures. Then, conduct the following inspection procedure.

PROCEDURE

1. CHECK FOR DTC (B2312)

(a) Check if DTC B2312 is output B2312.

OK:

DTC B2312 is not output.

NG -- GO TO DTC B2312 B2312
OK -- Continue to next step.

2. READ VALUE USING TECHSTREAM (MULTIPLEX NETWORK MASTER SWITCH)

(a) Use the Data List to check if the multiplex network master switch is functioning properly Scan Tool Testing and Procedures.

D-Door Motor

OK:

On tester screen, each item changes between ON and OFF according to above chart.

NG -- CHECK HARNESS AND CONNECTOR (MULTIPLEX NETWORK MASTER SWITCH ASSEMBLY - BATTERY AND BODY GROUND)
OK -- Continue to next step.

3. PERFORM ACTIVE TEST USING TECHSTREAM (POWER WINDOW)

(a) Select the Active Test, use the Techstream to generate a control command, and then check that power window regulator motor operates Scan Tool Testing and Procedures.

D-Door Motor

OK:

The power window regulator motor operates normally.

NG -- REPLACE FRONT POWER WINDOW REGULATOR MOTOR ASSEMBLY LH Removal

OK -- REPLACE MAIN BODY ECU (MULTIPLEX NETWORK BODY ECU) Scan Tool Testing and Procedures

4. CHECK HARNESS AND CONNECTOR (MULTIPLEX NETWORK MASTER SWITCH ASSEMBLY - BATTERY AND BODY GROUND)

(a) Disconnect the K3 multiplex network master switch connector.

(b) Measure the voltage according to the value(s) in the table below.

6. CHECK HARNESS AND CONNECTOR (MULTIPLEX NETWORK MASTER SWITCH ASSEMBLY - FRONT POWER WINDOW REGULATOR MOTOR ASSEMBLY LH)

(a) Disconnect the K3 multiplex network master switch connector.

(b) Disconnect the K6 power window regulator motor connector.

(c) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.

7. INSPECT FRONT POWER WINDOW REGULATOR MOTOR ASSEMBLY LH

(a) Remove the front power window regulator motor LH Removal.

(b) Check that the window regulator motor moves smoothly as follows.

NOTICE:
* Do not apply positive (+) battery voltage to any terminal other than terminal 2 (B) to avoid damaging the pulse sensor inside the motor.
* Reset the power window regulator motor (initialize the pulse sensor) after installing the power window regulator motor to the door.

OK:
