Danger: High voltage enabling and disabling shall be only performed by High Voltage Qualified Technicians. The procedures for high-voltage enabling/disabling can be found in the service instructions and must be strictly followed at all times. The usage of the Protocol High Voltage Disabling/Enabling is mandatory. The High-Voltage Qualified Technician is responsible for the adherence to the manufacturer's service instructions as well as current national legal regulations.

Failure to follow the procedures exactly as written may result in serious injury or death.

Questions regarding training can be answered by your national training centre.

Danger: Follow the safety regulations for hybrid/electric vehicles. The High-Voltage Qualified Technician is responsible for the adherence to the manufacturer's service instructions as well as current national legal regulations. Failure to follow the regulations exactly as written may result in serious injury or death.

Danger: Any hybrid/EV battery pack replacement shall be performed by High-Voltage Qualified Technicians only. The replacement procedure can be found in the service instruction and must be strictly followed at all times. The High-Voltage Qualified Technician is responsible for adherence to the manufacturer's service instructions as well as current national legal regulations. If the hybrid/EV battery pack needs to be replaced contact the Technical Assistance Centre for further instructions prior to removal of the battery pack.

Note: Print this form. Perform the High-Voltage Enabling procedures listed. Check off the individual steps as they are completed.

Note: A suitable hoist to safely lift the vehicle up is required to perform the enabling procedure.

Review the high-voltage safety information prior to performing the High-Voltage Enabling procedure. Refer to High Voltage Safety .

Procedure Description

Step Completed

1

Replace the GREEN HIGH VOLTAGE ENABLED with the RED HIGH VOLTAGE DISABLED sign.

O

2

Ensure the area around the vehicle is restricted and marked as such via warning cones, cordon tape or chain. Ensure all personnel not tasked with enabling the High-Voltage System have cleared the area.

O

3

Ensure that the keys and the S15 Hybrid/EV Battery Pack High Voltage Manual Disconnect Lever are securely stored outside the vehicle.

O

4

Disconnect and remove any 12 V battery chargers and cables, if connected.

O

5

Ensure that the 12 V battery is disconnected and the pole is covered to prevent uncontrolled reconnection with the battery cable.

O

6

Secure the vehicle from rolling, set transmission selector to park (P) position.

O

7

Verify if, and which repairs, were performed on the vehicle related to the High-Voltage System and that they are properly documented in the relevant work order file.

O

8

Note: Always tighten the high-voltage fasteners to the specified torque. Insufficient or excessive torque will cause malfunctions or damage.

After finishing work on the high-voltage systems and before reinstalling the high-voltage manual disconnect lever, inspect for the following:

Verify that all tools or loose components have been removed.
Verify high-voltage system integrity and that all connectors are installed.
Verify that all high-voltage interlock circuit connectors and covers are installed.
Install any components or connectors that have been removed or replaced during diagnosis.

O

 

Test Performed

9

If any high-voltage components or wiring had been removed, an electrical test of the earth connections must be performed with the EL-50774 and the 4-wire test leads. Refer to Earth Connection Resistance Test.

Yes

O

No

O

10

Install the S15 hybrid/EV battery pack high-voltage manual disconnect lever (1).

O

11

Connect the 12 V battery. Refer to Battery Negative Cable Disconnection and Connection .

O

12

With the bonnet open, start the engine, then Vehicle OFF.

O

13

Vehicle in Service Mode, perform the driver's window express learn and clear all DTC Information with a scan tool. Refer to Window Motor Programming - Express Function .

O

14

Vehicle OFF and all vehicle systems OFF. It may take up to 2 minutes for all vehicle systems to power down.

O

15

Vehicle in Service Mode, verify with a scan tool no DTCs are set.

If DTCs are set, go to the appropriate DTC information. Refer to Diagnostic Trouble Code (DTC) List - Vehicle .

O

16

Start and idle the engine for 2 minutes.

O

17

Vehicle OFF and wait 5 minutes.

O

18

Vehicle in Service Mode, verify with the scan tool the T6 traction power inverter module and K114B hybrid/EV powertrain control module 2 DTC Information that the following DTCs have Ran Since Code Clear and have not set:

  1. Motor position sensor learn DTCs P0C17 and P0C18.
  2. Contactor DTCs P0AD9, P0ADD, P0D0A, P0D11, P0AE4 and P1EBC.
  3. Discharge and Pre-charge DTCs P0C76, P0C77, P0C78 and P0AFB.
  4. High-voltage loss of isolation DTCs P0AA6, P1AE6 and P1F0E.
If the DTCs have Run and Passed, test drive the vehicle and verify no DTCs are set.
If the DTCs are set, go to the appropriate DTC information. Refer to Diagnostic Trouble Code (DTC) List - Vehicle .
If the DTCs have Not Run Since Code Clear, review and operate the vehicle according to the applicable DTC Conditions for Running and ensure the DTCs run and pass.
