Resets the Rear Drive Inverter and Pedal Monitor (PMR) Electronic Control Unit (ECU). Reset is executed via Unified Diagnostics Services (UDS) over the Controller Area Network (CAN).
TEST-RESET_PMR
Tests communication with the Pedal Monitor Slave (PMS) Electronic Control Unit (ECU). Communication is established via Unified Diagnostics Services (UDS) over the Controller Area Network (CAN).
PING-TP_PMS
Before executing this routine, a Controller Area Network (CAN) redeploy must pass. After an High Voltage (HV) Battery replacement, this routine runs all required tasks. Execute this routine after installing a HV battery. The first responder loop must be disconnected and the Low Voltage (LV) battery must be connected to a float charger.
PROC_BMS_X_PACK-REPLACEMENT
This routine executes a sequence of actions needed to be taken following a pack contactor replacement. This routine shall ONLY be executed after installing new pack contactors or on rare occasion when instructed to do so by engineering. See Toolbox Article 6864000 for more information.
PROC_BMS_X_CONTACTOR-REPLACEMENT
This network will run all required tasks after a steering wheel replacement
PROC_VCLEFT_X_STEERING-WHEEL-POST-REPLACEMENT-PROCEDURE
