BDY Pektron VIN Learn

This routine performs the VIN Learn, and side configuration learn for Pektron door module. This is necessary to ensure the body controller (BDY) recognizes the correct vehicle configuration. Test will always report as passed to MES due to unreliability of the routine. Routine is necessary after any configuration changes that affect the BDY module.

Bleed IDB RCU brake control internal volumes

Executes the SERVICE_BLEED routine for both IDB and RCU for 14 cycles. Supplier recommendation is 5x executions (70 total). LEAVE THE CALIPER BLEED NIPPLES CLOSED! Do not press the pedal during execution.

Blocked Contactors - Attempt to Clear

Clears open Voltage Sensing Harness (VSH) latch alerts and isolation counters. Resets the High Voltage Processor (HVP) and High Voltage Battery Management System (HVBMS) Electronic Control Units (ECU) in an attempt to clear blocked contactors. Even in the case all internal routines PASS, contactors may still be blocked from closing due to other external conditions.

Blower Identification Routine

Holds the blower stopped, performs high frequency voltage injection, detects blower type, and sets blower type over LIN

BMS - Clear Isolation Counters

Clears the Battery Management System (BMS) isolation counters, which clears BMS_w/f027_SW_Drive_Iso_Repeated and BMS_w/f172_SW_Drive_Iso_Warning alerts. Execute this routine after repairing any isolation issue on the vehicle's High Voltage (HV) system. The BMS isolation counters latch the alerts BMS_w/f027 and BMS_w/f172 when reaching a specific count threshold.

BMS ECU Backup

This routine creates a backup copy of data from the Battery Management System (BMS) ECU and saves it onto the car computer. The backup data is needed when performing a BMS ECU Restore.

PROC_BMS_X_ECU-REPLACEMENT-BACKUP

Model S / X (legacy)
Service procedures

BMS ECU Restore

This routine writes the most recently saved Battery Management System (BMS) ECU backup data on the car computer to the newly installed BMS. See Toolbox Article 6988500 for more specific details. Requirements: - New compatible BMS is installed - CAN Redeploy successfully completed to allow GTW unlock procedure - First responder loop disconnected (pack contactors open) - LV battery supported by a LV maintainer

PROC_BMS_X_ECU-REPLACEMENT-RESTORE

Model S / X (legacy)
Service procedures

BMS Reset

Resets the Battery Management System (BMS). The first responder loop must be disconnected and the Low Voltage (LV) battery must be connected to a float charger.

Boot Status

Check boot status of the VCFRONT

Bosch EPAS Calibration

Calibrates Bosch Electric Power Assisted Steering (EPAS) by flashing the Electronic Control Unit (ECU), resetting steering soft lock stops, and angle compensation.

BOSCH Radar Service Drive Alignment

This Routine is checking the calibration of the BOSCH Forward Facing Radar. The vehicle needs to be driven on a straight road with a minimum speed of 30mph/50kph. The progress bar will show current progress and will update depending on the road/drive conditions. Reasons for not updating are: Speed might be too low/high or the steering wheel is not straight enough. When the vehicle is put into park when the routine is not completed, this will ABORT the routine.

Calibrate 2nd Row Seat - Center Pitch

The second row pitch calibration sets the soft end stops for the seat's pitch hall sensor. In General Assembly, all seats should arrive pre-calibrated to end of line testing. This particular routine will first check for a valid calibration and pass if it is present. If it is not pre-calibrated, the seat will pitch backwards until the seat latches. Once the latch is detected, the seat will pitch forward until reaching a stall current at the latch, and then back off to a home position (zero position). If the seat does not latch within 2 seconds during the first step, or encounters an obstacle while approaching the home position, the routine will fail. If the seat is pitched too far forward at the start of the routine, the calibration will fail on the first attempt.

Calibrate 2nd Row Seat - Center Track

The second row track calibration sets the soft end stops for the track. There is a hall sensor mounted to the track, which in combination with a 100mm metal shunt in the rearward end of travel is used to determine whether the seat is in the comfort zone. When the calibration is run, if the seat is forward of the shunt (forward 220mm of travel), the seat will move rearward until the hall sensor reaches the edge of the shunt. If the seat is in the comfort zone, the seat will move forward until the hall sensor reaches the edge of the shunt. Make sure seat install mode is turned OFF before calibrating.

Calibrate 2nd Row Seat - Left Pitch

The second row pitch calibration sets the soft end stops for the seat's pitch hall sensor. In General Assembly, all seats should arrive pre-calibrated to end of line testing. This particular routine will first check for a valid calibration and pass if it is present. If it is not pre-calibrated, the seat will pitch backwards until the seat latches. Once the latch is detected, the seat will pitch forward until reaching a stall current at the latch, and then back off to a home position (zero position).

Calibrate 2nd Row Seat - Right Pitch

The second row pitch calibration sets the soft end stops for the seat's pitch hall sensor. In General Assembly, all seats should arrive pre-calibrated to end of line testing. This particular routine will first check for a valid calibration and pass if it is present. If it is not pre-calibrated, the seat will pitch backwards until the seat latches.
