Battery Energy Control Module (G2261602): Removal
WARNING:
- This procedure must only be carried out after approval from Jaguar Land Rover (JLR).
- Before any component replacement all technicians must follow the correct diagnostic guided flow for the Diagnostic Trouble Codes (DTC's) present on the vehicle.
- This procedure must be carried out in the exact sequence shown below. Failure to do so could result in serious personal injury.
- It is the responsibility of the Electric Vehicle Senior Authorized Person (EVSAP) to make sure they comply with any local legislation for work on High Voltages (HV).
- This procedure requires the use of both Class 0 and Class 1 Personal Protective Equipment (PPE), all persons involved in this procedure must have read and understood the PPE requirements as detailed in article ELECTRIC VEHICLE SAFETY RULES .
- The approved Personal Protective Equipment (PPE) must be worn where indicated by the orange PPE icons within this procedure, all persons involved in this procedure must have read and understood article ABOUT THIS SERVICE INFORMATION before continuing.
- All PPE equipment must be checked for wear or damage prior to use and replaced if damaged.
NOTE:
All Live Work Certificates (LWC) must be kept for a minimum of 5 years.
-
WARNING: Jaguar Land Rover Electric Vehicle Senior Authorized Person (EVSAP) trained technicians only.
- This procedure involves live working on Electric Vehicle (EV) battery components. Only technicians qualified to EVSAP level and trained for live work on the I-Pace (X590) EV battery are allowed to perform this procedure . It is mandated that all technicians involved with the steps in this procedure have read and understood the Electric Vehicle (EV) Safety Rules. Refer to: ELECTRIC VEHICLE SAFETY RULES .
- The EVSAP must issue a Live Work Certificate (LWC) before any work can commence.
Refer to: LIVE WORKING CERTIFICATE .
Make sure the Danger sign is clearly visible to anyone outside of the live work area.
- Remove the Battery Electrical Module (BEM).
Refer to: BATTERY ELECTRICAL MODULE .
- The following steps require the safety accompanying person with the safety hook outside the live working area, this person must remain in position for the duration of this procedure.
-
WARNING: This step is for information only, all technicians must read and understand these steps before continuing.
- Replacement of the Battery Energy Control Module (BECM) in this procedure is considered live working. Graphic E243208 shows the component and electrical circuit layout of the Battery Electrical Module (BEM) baseplate assembly.
- Callout A shows the Service Disconnect Unit (SDU) and a HV sensing wire (21) connected directly to the positive side of the HV circuit. The HV sensing wire (21) is connected to pin 21 on the BECM connector as shown above in callout B, this wire will always have a direct connection to positive side of the HV circuit regardless of the SDU key position.
- Callout C shows the HV terminals providing an HV circuit to the BEM, the negative terminal (circled in the callout) is connected directly to the negative side of the HV circuit.
- During the replacement of the BECM all technicians must be aware that there will always be maximum EV battery voltage (approximately 400V) between pin 21 of the BECM connector (B) and the negative HV terminal (C). Under no circumstances should these two points be connected .
Install the insulated sheath over the baseplate negative terminal.
