Battery replacement
After replacement of the battery, the service function
”Register battery replacement”
must be used to inform the power module of the battery replacement.
Registering the battery replacement
Why register the battery replacement?
After fitting a new battery, the service function 'Register battery replacement' should be run. Registration of the battery replacement is necessary to notify the power management (software in the engine electronics and intelligent battery sensor) that a new battery has been fitted in the vehicle.
Without registration of the battery replacement, the power management does not run properly and this can lead to function limitations, for example reduction or deactivation of individual consumer units.
Register battery replacement
This function informs the power management in the DME/DDE of a battery replacement. The following operations are performed:
•The current kilometre reading is stored for the battery replacement.
•The stored measured values (battery charge statuses, current, voltage, temperature, etc.) are deleted.
•The power management is initialised.
Replacing the battery: other battery capacity or AGM battery
As the battery depends on the engine ands options fitted, the following information is coded in the CAS:
•Battery capacity (for example 90 Ah)
•Battery type: AGM battery or lead-acid battery.
In the case of battery replacement, in general the battery capacity used as series standard may be used.
On installation of a battery with higher or lower capacity or installation of an AGM battery, Progman must be used to recode the CAS.
