Preparations For Standby Current Measurement
When the vehicle enters the usage mode abandoned the control modules and the communication buses are set to sleep mode, which reduces the power consumption. Factors such as whether the vehicle is locked, the alarm is on or off or whether any doors are open affect the rate at which the vehicle will reach standby power consumption. The lowest power consumption is achieved the quickest when the vehicle is locked, the alarm is on and the vehicle's hatches and doors are closed.
Use the tool "Vehicle SoC, voltage and current history" to help determine whether fault tracing of high standby consumption is warranted.
Preparations
- Ensure that all lighting is switched off.
- Ensure that the diagnostic tool is not connected in the vehicle.
- Ensure that there is no key near the vehicle.
- Open the tailgate or trunk lid and bonnet and set the locks to the deadlocked position using a screwdriver for example.
- Open the driver's and passenger doors and set the locks to the deadlocked position using a screwdriver for example.
- Ensure that the power windows are in closed position.
Activate the function for reduced alarm via the Center Console Display (CCD) in order to be able to work inside the center console without risking activation of the alarm.
Close the rear doors, remove the key and lock and alarm the vehicle. If all locks are set to lock position when alarm arming is requested, the vehicle indicates this by flashing the indicators briefly.
Wait until the vehicle has come down to standby current consumption, which can take up to 25 minutes.
Do not open any doors or the test will have to be restarted from the beginning. Be aware that if the vehicle is equipped with foot motion detector module FMDM there is a risk of the workshop personnel accidentally activating the sensor by being directly behind the vehicle, and thus affecting the standby current consumption. Ensure an active connection attempt to the vehicle via the workshop's WiFi is not performed.
