B152E00: Function limitation due to safety function low voltage
Diagnostic trouble code B152E00 — what it means, the common
causes, and how to confirm the real fault before replacing parts.
What does B152E00 mean?
B152E00 indicates: Function limitation due to safety function low voltage.
This relates to the Body system.
Common causes of B152E00
low voltage in the safety-relevant electrical sub-system
fault in the terminal 30_0 electrical sub-system affecting safety-relevant systems
insufficient power supply to safety-relevant systems monitored by J1282
What to check (live data)
electrical system voltage monitored by J1282
supply path voltage for electromechanical power steering
Parts often involved in B152E00
control unit for low-voltage power distribution J1282
safety-relevant wiring (labelled with '_s' or '_!' in current flow diagram)
Don't replace parts until the root cause is confirmed — many of these codes are caused by wiring, a connector or an upstream fault, not the part itself.
Get the confirmed root cause for B152E00 — on YOUR vehicle
A code is a symptom, not a diagnosis. AutoDX Pro cross-checks several
independent assessments, pinpoints the actual root cause, gives you the
exact tests to confirm it, and shows the parts — only after the cause is
confirmed. Reads your scan-tool photo and decodes your VIN with open
recalls.
B152E00 is a diagnostic trouble code: Function limitation due to safety function low voltage.
What are the common causes of B152E00?
Common causes include: low voltage in the safety-relevant electrical sub-system, fault in the terminal 30_0 electrical sub-system affecting safety-relevant systems, insufficient power supply to safety-relevant systems monitored by J1282. The exact cause depends on the vehicle — confirm it before replacing parts.
Can I keep driving with B152E00?
It depends on the fault and your symptoms. Some causes are minor, others can damage components or affect safety. Get the root cause confirmed before deciding.
How do I fix B152E00?
Confirm the actual root cause with targeted tests first, then replace only the part that's at fault. AutoDX Pro gives you the root cause, the exact tests, and the parts for B152E00 on your specific vehicle.
