My 05 was throwing this code. The module with the lowest voltage was the one this method also pointed to. Changed that module and no more code. Thanks.
The voltage difference test is meaningless in this case, the 80V you measured is not leakage, it's because the case it tied to the negative of the battery, so you're just measuring the voltage of all the batteries combined until the battery you're on, to ground, sums up to be 80V, not 80V of leakage.
Please explain how you believe the case is tied to the the main ground ground. The Voltage sense module is isolated in the video and non of the contactors/relays are on. Based on the vehicle schematics/diagrams there is nothing tying the case to the high voltage ground.
@@carlosmedrano8656 I don't have the schematic, but I'm sure if you check for continuity on across the system negative and the metal body of the hybrid batter, they will be connected internally, I remember seeing the green cable tied to the output negative of the battery. I am searching for a similar error and will have to take it apart and will confirm whether that is true or not.
@@ahmedsaid3967 With the Voltage sense module connected your will have continuity, there is a series of resistors inside for high voltage detection. So if you checked with the module connected, then yes. Also if look closer at the issue you are having, the service manual breaks it down into three sections. The battery itself, the main high voltage cables to inverter/ and the MG1-MG2 and A/C compressor sections. This video is focused on the battery pack itself, not the other sections.
