SERVICE:
*Make sure that the vehicle is on V2.9 Software or later, which is available in VIDA beginning
2023w20d1, and charge the battery if needed.
Attention: Do not disconnect the 12V battery prior to fault tracing. Perform analysis swiftly
upon battery drainage, as symptom may disappear over time.
•
If the vehicle has been unlocked at any time during the last 48hrs and has a quiescent current of
~30-50mA, this can be considered normal.
•
Measure quiescent current using the method located in VIDA with a clamp-type amp meter ~10
minutes after locking the vehicle. (NOTE: BEV vehicles wake up once every hour to charge the
12v battery. This is normal behavior)
•
Use the “Quiescent current in control modules” method in VIDA to identify a fuse or a circuit
with a high quiescent current. To locate the “Quiescent current in control modules” method in
VIDA do the following:
1. After vehicle Read out completes, use CSC Fault tracing for CSC LM: “12 V main battery, Dead
battery” and Function “Electrical distribution: 12V system”
-
Add the CSC to a Work List and then select Guidance to take you to guided fault tracing
2. In the Component and Actions list, locate “Quiescent current in control modules” and follow the
procedure outlined in there.
When the fuse/circuit has been identified, please note the “Current” value. Submit the value in a
Vehicle Report outlining the complete fault tracing that has been performed. Use guidelines under
Vehicle Report to create the report.
NOTE: This TJ is for information collection/reporting only. Do not replace any components. If
technical assistance is required, contact Retailer Technical Support following the guidelines
under “Vehicle Report.”
