INSPECTION PROCEDURE
When "System initializing" is displayed on the display and navigation module display after the cable is disconnected from the negative (-) battery terminal, correct the steering angle neutral point ().
Depending on the parts that are replaced or operations that are performed during vehicle inspection or maintenance, calibration of other systems as well as the side monitor system may be needed ().
Inspect the fuses for circuits related to this system before performing the following inspection procedure.
| 1.CHECK DISPLAY CHECK MODE |
Check which items display "CHK" (red) on the [Signal Check] screen.
Result| Result | Proceed to |
| "CAMERA SW" and "WFS SET" displays "CHK" (red). | A |
| "MIRROR SW" displays "CHK" (red). | B |
| "VGRS" displays "CHK" (red). | C |
| "CAN" displays "CHK" (red). | D |
| 2.INSPECT FRONT AND SIDE MONITOR MAIN SWITCH ASSEMBLY |
Remove the front and side monitor main switch assembly ().
Inspect the front and side monitor main switch assembly ().
| | REPLACE FRONT AND SIDE MONITOR MAIN SWITCH ASSEMBLY ()
|
|
|
| 3.CHECK HARNESS AND CONNECTOR (FRONT AND SIDE MONITOR MAIN SWITCH ASSEMBLY - PARKING ASSIST ECU, BATTERY AND BODY GROUND) |
Disconnect the G15 front and side monitor main switch assembly connector.
Disconnect the F76 parking assist ECU assembly connector.
Measure the voltage according to the value(s) in the table below.
- Standard Voltage:
| Tester Connection | Switch Condition | Specified Condition |
| G15-6 (IG) - Body ground | Engine switch on (IG) | 11 to 14 V |
| G15-6 (IG) - Body ground | Engine switch off | Below 1 V |
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
| Tester Connection | Condition | Specified Condition |
| F76-7 (BLSW) - G15-9(ECU) | Always | Below 1 Ω |
| G15-9 (ECU) - Body ground | Always | 10 kΩ or higher |
| G15-6 (IG) - Body ground | Always | Below 1 Ω |
| | REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
|
| OK | |
| |
| REPLACE PARKING ASSIST ECU ()
|
|
| 4.INSPECT OUTER MIRROR SWITCH ASSEMBLY |
Remove the outer mirror switch assembly ().
Inspect the outer mirror switch assembly ().
| | REPLACE OUTER MIRROR SWITCH ASSEMBLY ()
|
|
|
| 5.CHECK HARNESS AND CONNECTOR (OUTER MIRROR SWITCH ASSEMBLY - PARKING ASSIST ECU) |
Disconnect the F75 parking assist ECU connector.
Disconnect the G16 outer mirror switch assembly connector.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
| Tester Connection | Condition | Specified Condition |
| F75-5 (MPOS) - G16-6 (MR) | Always | Below 1 Ω |
| F75-5 (MPOS) - Body ground | Always | 10 kΩ or higher |
| G16-5 (E) - Body ground | Always | Below 1 Ω |
| | REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
|
| 6.CHECK POWER MIRROR CONTROL SYSTEM (POWER RETRACT FUNCTION) |
Check the power mirror control system (power retract function) ().
- OK:
- Power mirror control system (power retract function) is normal.
| | Go to POWER MIRROR CONTROL SYSTEM ()
|
|
|
| OK | |
| |
| REPLACE PARKING ASSIST ECU ()
