SERVICE:
With any HVB (High Voltage Battery), you must be certified to carry out HVB repairs to the
correct competence. Always repair the battery according to the methods in VIDA. When performing
any measurements, it is important that the AA batteries in the measuring tool are above 75% charge
minimum. This is confirmed when you turn the meter on, briefly displaying a value. Before you start
measuring it is good to check how the tool displays short to ground and open loop.
In the rare event that a complete battery is to be replaced, the battery being installed may not have the
same cell chemistry as the battery being removed.
*A unique SP (Software Product) may be necessary, see attachment “Sp list 34295.pdf”.
The SP (Software Product) changes the Variant Attribute in the vehicle to match that to the replacement
battery.
The information of what battery is installed in the vehicle could be found in VIDA, Vehicle details,
Variant attribute and search for VDN code CK0.
Cell Module: This part is most often used when one cell is defective. The most common cell defects are
seen as one cell having a lower Open Circuit Voltage (OCV) and State of Charge (SoC) than all other
cells. Normal SOC deviation is less than 5%, more than 10% is a fault. The cell module is delivered
complete with temperature sensors and a Cell Voltage and Temperature Node. Examples are attached in
“HVB - Cell Voltage Overview”
Cell modules are available for the following variants:
• MY 2018-2019 SPA P30
• MY 2020-2021 SPA P34
Note that cell module replacement is also the recommended repair for:
• MY 2016-2017 SPA where the original P27 battery has been previously replaced with a P30 battery.

2023-01-13
Technical Journal 34295.7.0
Cell module replacement is not available for:
• MY 2016-2017 SPA P27 battery
Service Kit: This kit is helpful to have on hand when replacing a cell module in the event that a cable,
clip, or seal is damaged during the repair.
Coolant level: After repair or reassembly of the cooling system it is important to refill and bleed the
high-voltage coolant circuit correctly according to VIDA. It takes some time for the cooling system to
stabilize. After thoroughly road testing the vehicle, the coolant level should be visually checked once
more.
CVTN (Cell Voltage and Temperature Node): This part is used when there is a DTC (Diagnostic
Trouble Code) confirming an internal fault. It is also used when there is a measurement error, for
example, several adjacent cells show incorrect cell voltage. Examples are attached in “HVB - Cell
Voltage Overview”
Fuses: These are used when a Diagnostic Trouble Code is set for an open fuse.
The root cause for the open fuse needs to be fault traced and corrected before replacing the fuse.
Coolant Temperature Sensor: This part is used when the temperature sensor does not read accurately.
Check the accuracy by allowing the car to soak for several hours, preferably overnight. The signal
can then be checked for an offset by comparing it to other sensors in the car. Use a VIDA Diagnostic
Sequence or choose a selection of temperature sensors from various nodes in the vehicle.
BDU (Battery Distribution Unit): This part is most often used when a Diagnostic Trouble Code is
set for one or more stuck contactor(s). It can also be used when a diagnostic trouble code is set for the
current sensor. A stuck contactor can be confirmed by following Vida and using the measurement tool.
BECM (battery energy control module): This part is most often used when a Diagnostic Trouble Code
is set for an internal fault or the unit does not communicate on the CAN bus. When a battery energy
control module becomes non-responsive during a software download, it is often not necessary to replace
it. It can usually be recovered using VIDA Software Advanced Test. If the battery energy control module
cannot be recovered using VIDA, create a Vehicle Report, Support Needed.
Circuit board: This part is most often used when there is an intermittent or permanent open in one
of the circuits, such as the power, ground, CAN, interlock, or Supplemental Restraint System Airbag
system (SRS). In most cases, however, the actual fault is in the vehicle wiring outside the battery itself.
Gasket: It is not necessary to replace the gasket each time the battery is opened, but it is required to
perform the leakage test in VIDA after a repair.

Isolation test:
It is not necessary to perform an isolation test for all hybrid issues.
It is necessary when specifically instructed to do so according to the fault tracing or repair method.
When performing measurements, it is important that the AA batteries in the tool are above 75% charge.
This is confirmed when you turn the meter on, briefly displaying a value.
Before you start measuring familiarize yourself with how the tool displays short and open circuits.
VEHICLE REPORT:
Please submit a Vehicle Report if the service solutions described in this TJ have no effect. Use concern
area “Vehicle Report” and sub-concern area “Support Needed”, use function group 3113.
