Identifying The Correct High-Voltage Disable Procedure: Mercedes-Benz
I-CAR · October 13, 2023 · Mercedes-Benz
Summary
This article explains that Mercedes-Benz provides two distinct high-voltage disable procedures in their repair manuals: a primary scan-tool-based method and a secondary manual physical isolation method. The manual procedure is only to be used if the diagnostic system cannot perform the power disable.
What to do on the job
Always attempt to deenergize the high-voltage system using a diagnostic scan tool first, and only perform the manual physical isolation procedure if the scan tool method cannot be completed.
How to use it
Use this document to justify the necessary diagnostic scan tool time and labor for high-voltage disabling, or to defend the additional labor, PPE, and specialized HV DVOM equipment required if a manual physical isolation procedure becomes necessary.
