HINT
* Use the following procedure to troubleshoot the power window control system.
* *: Use the Techstream.

1. VEHICLE BROUGHT TO WORKSHOP

NEXT -- Continue to next step.

2. CUSTOMER PROBLEM ANALYSIS

* In troubleshooting, confirm that the problem symptoms have been accurately identified. Preconceptions should be discarded in order to make an accurate judgment. To clearly understand what the problem symptoms are, it is extremely important to ask the customer about the problem and the conditions at the time the malfunction occurred.

* Gather as much information as possible for reference. Past problems that seem unrelated may also help in some cases.

* The following 5 items are important points in the problem analysis:

3. PRE-CHECK

(a) Measure the battery voltage.

Standard Voltage:

11 to 14 V

If the voltage is below 11 V, recharge or replace the battery before proceeding to the next step.

(b) Check the fuses and relays.

(c) Check the connector connections and terminals to make sure that there are no abnormalities such as loose connections, deformation, etc.

NEXT -- Continue to next step.

4. INSPECT COMMUNICATION FUNCTION OF BEAN COMMUNICATION SYSTEM*

(a) Use the Techstream to check if the BEAN Communication System is functioning normally Multiplex Communication System.

Result:





B -- GO TO BEAN COMMUNICATION SYSTEM Multiplex Communication System
A -- Continue to next step.

5. CHECK FOR DTC (RETRACTABLE HARDTOP SYSTEM)*

(a) Clear for DTCs Reading and Clearing Diagnostic Trouble Codes.

(b) Recheck for DTCs.

Result:





B -- GO TO RETRACTABLE HARDTOP SYSTEM Retractable Hardtop System
A -- Continue to next step.

6. PROBLEM SYMPTOMS TABLE

(a) Refer to the Problem Symptoms Table Problem Symptoms Table.

Result:





B -- Go to step 8
A -- Continue to next step.

7. OVERALL ANALYSIS AND TROUBLESHOOTING*

(a) Operation Check Operation Check

(b) Terminals of ECU Pinout Values and Diagnostic Parameters

(c) Data List / Active Test Scan Tool Testing and Procedures

NEXT -- Continue to next step.

8. ADJUST, REPAIR OR REPLACE

(a) Check if any of the power window regulator master switch assembly, power window regulator switch assembly, door window regulators or power window regulator motor assemblies have been removed and reinstalled.

Result:





B -- Go to step 10
A -- Continue to next step.

9. RESET POWER WINDOW CONTROL SYSTEM

(a) If any of the power window regulator master switch assembly, power window regulator switch assembly, door window regulators or power window regulator motor assemblies have been removed and reinstalled, perform "Initialize Power Window Control System" (initialization of the pulse sensor) for the applicable door glass Initialization.

NEXT -- Continue to next step.
