Automatic start/stop of engine

(only on vehicles with the function Automatic start/stop of engine).

Secondary Battery Relay
Shows if the Central electronic module (CEM) requests from Engine control module (ECM) that the secondary battery relay should be activated or not. Central electronic module (CEM) requests activation of the relay when the secondary battery needs to be charged.

Voltage secondary battery
Shows secondary battery's voltage.
Measurement range 0-18 V.
When the engine is running (alternator charges) and the secondary battery is connected to the vehicle's electrical system, the secondary battery's voltage will be the same as the rest of the electrical system's voltage. If the secondary battery disconnected, the voltage will be lower.

Voltage secondary battery, latest stored
Shows secondary battery's latest stored voltage.
Measurement range 0-18 V.
For every new driving cycle, the Central electronic module (CEM) measure the voltage on the secondary battery and stores this value. If the vehicle has been parked with the ignition off for more than approx. 10 hours, the Central electronic module (CEM) uses the new voltage value to calculate how long time the secondary battery needs to be charged. If the vehicle has been parked with the ignition off for less than approx. 10 hours, the Central electronic module (CEM) uses the previously stored voltage value to calculate how long time the secondary battery needs to be charged.

Voltage secondary battery, lowest average value
Indicates the secondary battery's lowest stored average voltage.
Measurement range 0-18 V.
Every time auto start is activated, the Central electronic module (CEM) continuously reads the secondary battery's voltage during the start sequence (during the time the secondary battery supplies the vehicle). The lowest value that is registered is saved by the Central electronic module (CEM) in its memory. At the next auto start, this sequence is repeated and the Central electronic module (CEM) calculates the average value of the previously registered voltage values and the last value. The average value is calculated at every auto start. This average value forms the basis for the secondary battery's SOC and capacity. If the calculated average voltage falls below 10.4 V in the actual operating cycle, the automatic start/stop of the engine function is no longer permitted. This is to prevent the battery from discharging to much.
