Hybrid BATTERY RECIRCULATION DOOR POSITIONING MOTOR 2 -V480-, REMOVING AND INSTALLING: Notes

WARNING: This page is about a different variant/trim than selected.

ON VEHICLES WITH A HIGH VOLTAGE SYSTEM (Hybrid VEHICLES)

Observe All Of The Additional Warnings For All Work Performed On Vehicles With The High Voltage System. Refer To HIGH VOLTAGE VEHICLES SAFETY PRECAUTIONS .

If It Is Necessary For The Following Procedure To Perform Work Near High Voltage Components, "Perform A Visual Inspection Of The High Voltage Components And Cables For Damages" And "Always Follow The Warnings When Working On The High Voltage System". Refer To PERFORMING A VISUAL INSPECTION OF DAMAGE TO HIGH VOLTAGE COMPONENTS AND CABLES ) .

WARNING:

Risk Of Unintended Engine Start

The Ignition Must Be Turned Off And The Ignition Key Must Remain Outside Of The Vehicle When Working On Vehicles With A High Voltage System.

WARNING:

Handling High Voltage Cables:

Do Not Stand On Or Place Tools On High Voltage Cables And Their Components As It May Damage The Cable Insulation.
Never Bend Or Kink High Voltage Cables Forcefully As It May Damage The Cable Insulation.
The Round High Voltage Connectors Are Color Coded With An External Color Ring And Are Mechanically Coded Using The Guide- Or Code Tabs. Always Make Certain That The Coding Matches When Connecting The Round Connector In Order To Avoid Any Mechanical Damage The High Voltage Connector.

CAUTION:

There Is A Risk Of Electrocution From Damaged High Voltage Components.

Observe The Following When Working Around High Voltage Components And High Voltage Wires:

Never Work Around High Voltage Components And Cables With Cutting, Deformed, Or Sharp Edged Tools, Or Heat Sources Such As Welding Or Soldering Tools, Heated Air, And Thermal Glue.
Inspect The High Voltage Components Visually Before Beginning.
Perform A Visual Inspection Of The Electric Drive Power And Control Electronics -JX1-, The Electro-Drive Drive Motor -V141-, The Electrical A/C Compressor -V470- And The High Voltage Lines When Working In The Engine Compartment.
Perform A Visual Inspection Of The High Voltage Lines And Covers When Working On The Underbody.
Perform A Visual Inspection Of The High Voltage Lines And The Electrobox With The High Voltage System Maintenance Connector -TW- When Working In The Luggage Compartment.
Perform A Visual Inspection On All Of The Potential Equalization Cables.

Observe The Following Items When Performing The Visual Inspection:

The Components Do Not Display Any Signs Of External Damage.
The High Voltage Cable Insulation And The Potential Equalization Cables Are Not Damaged.
The High Voltage Cables Do Not Display Any Abnormal Deformations.
Every High Voltage Component Is Marked With A Red Warning Label.

NOTE:

For This Vehicle, Both Actuators (For The Hybrid Battery Recirculation Door Positioning Motor 1 -V479- And The Hybrid Battery Recirculation Door Positioning Motor 2 -V480-) On The Battery Cooling Module Are Activated By The Battery Regulation Control Module -J840- Via The Data Line. Both Actuators Are Connected The Battery Regulation Control Module -J840- Via The Data Line (Lin Bus). If An Incorrect Actuator Is Installed Or The Actuators On The Battery Cooling Module Are Switched, There Will Be A Malfunction At An Actuator Or In The Wiring. This Malfunction May Result In Various DTC Memory Entries With Different Malfunction Types Using The Vehicle Diagnostic Tester In The "Guided Fault Finding " function. Refer to the appropriate Wiring Diagram.

The Actuators On The Battery Cooling Module Are Identical To The Actuators On The A/C Unit, In That The Battery Regulation Control Module -J840- Cannot Perform Any Addressing Procedure For The Actuators. Only Actuators Which Are Already Addressed With The Correct Addresses May Be Installed On The Battery Cooling Module. When Replacing, Pay Attention To The Correct Version (Part Number) And When Installing, The Correct Component Location Using The Vehicle Diagnostic Tester In The "Guided Fault Finding " Function.

Note That In The Vehicle Diagnosis, Various Terms And Definitions Are Used For The Actuators Hybrid Battery Recirculation Door Positioning Motor 1 -V479- And Hybrid Battery Recirculation Door Positioning Motor 2 -V480- : The Hybrid Battery Recirculation Door Positioning Motor 1 -V479- Is Marked As "Valve 1 For The Air Guide For The Hybrid Battery", The Hybrid Battery Recirculation Door Positioning Motor 2 -V480- As "Valve 2 For The Air Guide For The Hybrid Battery".

CAUTION:

Make Sure That The Allocation For The Actuator Is Correct.

Both Positioning Motors (Hybrid Battery Recirculation Door Positioning Motor 1 -V479- And Hybrid Battery Recirculation Door Positioning Motor 2 -V480-) Are Identical. They Differ Only By Their Electronically Stored Allocation (Assignment).
If The Actuators Are Switched During Installation, The Activation Of The Doors In The Battery Cooling Module Will Be Incorrect, Resulting In A Faulty Air Guide For The Traction Battery -A2-.
Mark The Actuator And The Installed Position On The Battery Cooling Module Before Removal.
Pay Attention To The Markings When Installing And, If Necessary, Check The Part Number Of The Adjustment Motor.

NOTE:

Note The Correct Allocations. The Hybrid Battery Recirculation Door Positioning Motor 1 -V479- Has The Part Number "8R0 820 504" At The Start Of Production For Example And The Hybrid Battery Recirculation Door Positioning Motor 2 -V480- Has The Part Number "8R0 820 510".
