   YES	A
   NO (Connect the connector correctly) HINT:  Repair the connector if any broken pin or poor mating is detected.	B

Result: 

B 

See step  7

Result: 

A 

See step  7

1. Turn the ignition switch to ON.
2. Operate the power window regulator master switch assembly and check that the power window (driver's side) operates.

   Is the symptom removed?

   Result	Proceed to
   YES	A
   NO	B

Result: 

A 

SINCE THE POOR CONTACT OF CONNECTOR WAS REPAIRED, THE CIRCUIT CONDITION RETURNED TO NORMAL 

Result: 

B 

See step  8

1. Turn the ignition switch to OFF.
2. Disconnect the power window regulator motor assembly LH connector.
3. Turn the ignition switch to ON.
4. Using a tester, measure the voltage between the power window regulator motor assembly LH connector and chassis ground.

   Connector & terminal

   J4-5 - Chassis ground

   Is the voltage 10.0 V or more?

   Result	Proceed to
   YES	A
   NO	B

Result: 

B 

CHECK THE POWER SUPPLY CIRCUIT 

Result: 

A 

See step  9

1. Using the GTS, check the following items in the [Data List] of [Power Window (Driver)].

   Body Electrical > Power Window (Driver) > Data List 

   Tester Display	Measurement Item	Range	Diagnostic Note
   Operation Enable Signal	Operation permission signal	Not Permit Permit	-

   Body Electrical > Power Window (Driver) > Data List 

   Tester Display
   Operation Enable Signal

   Is [Permit] displayed?

   Result	Proceed to
   YES	A
   NO	B

Result: 

B 

INSPECT THE MAIN BODY ECU (MULTIPLEX NETWORK BODY ECU) 

Refer to HOW TO PROCEED WITH TROUBLESHOOTING [11/2021 - ]

If no fault is found in the main body ECU (multiplex network body ECU), replace the power window regulator motor assembly LH.

Refer to REMOVAL [11/2021 - ]

Result: 

A 

See step  10

1. Turn the ignition switch to OFF.
2. Disconnect the power window regulator master switch assembly connector.
3. Perform unit inspection of power window regulator master switch assembly.

   Refer to INSPECTION [11/2021 - ]

   Is the check result OK?

   Result	Proceed to
   YES	A
   NO	B

Result: 

B 

REPLACE THE POWER WINDOW REGULATOR MASTER SWITCH ASSEMBLY. Refer to  REMOVAL [11/2021 - ] 

Result: 

A 

See step  11

1. Using a tester, measure the resistance between power window regulator master switch assembly connector and power window regulator motor assembly LH connector.

   Connector & terminal

   J2-1 - J4-6

   J2-13 - J4-8

   Is the resistance less than 1 Ω?

   Result	Proceed to
   YES	A
