the battery when charging and do not place the Deutronic battery charger directly onto the battery unit.

2. Keep the battery on charge, using a Deutronic battery charger during the software downloading

procedure.

Care point: Both the driver and passenger windows must be in the fully open position during software

downloads.

Care point: All software downloads require the vehicle to be in ignition state 5.

Care point: During the software download process, it is normal for the instrument cluster displays to

extinguish temporarily.

Care Point: Ensure vehicle lift is in the lowered position before reprogramming the PCCU.

Suspension Displacement Sensor Calibration will fail to complete if the system is not fully lowered.
