Cooper S (R56) L4-1.6L Turbo (N14) (2009)
secured supply cable of the junction box electronics. All relays are controlled via the negative lead. All internal relays and the relay for wiper stage
1 and wiper stage 2 are located downstream of each fuse on the current circuit. All other external relays lie in the current circuit before the fuse.
Internal relays are:
-
Relay for the power window drives
-
Relay for the central-locking system
The external relays are:
-
Relay for drive, rear window wiper
-
Relay for wiper stage 1 and wiper stage 2 drives
-
Relay for headlight cleaning
-
Relay for heated rear window
-
Bi-stable relay (deactivation of closed-circuit current fault)
Notes for Service department
The following information on the junction box is available for service staff:
Notes on encoding / programming
Nearly all Car and Key Memory functions are programmed inside the vehicle itself.
No liability can be accepted for printing or other faults. Subject to changes of a technical nature.

Power Management
Reduction or shutdown of individual current consumers
The power management a subsystem of the energy management. The power management is run from the engine control module (DME or DDE: digital
engine electronics or digital diesel electronics).
A function of the Advanced Power Management (APM) is the shutdown of individual consumer units or the reduction of power intake. The APM is only
implemented in vehicles with the intelligent battery sensor.
System functions
The following system functions are described for power management ("Advanced Power Management"):
-
Reduction or shutdown of individual current consumers
Reduction or shutdown of individual current consumers
The cutoff of individual consumer units or reduction of the power consumption lowers the power consumption in critical situations. This prevents the
battery from discharging.
IMPORTANT: When the shutdown of individual consumer units or the reduction of power consumption is activated, the displays remains active
(LEDs remain lit).
With the engine running
With the engine running, the shutdown of individual consumer units or reduction in the power consumption is only activated under 2 conditions:
-
Battery charge state in the critical range
-
Alternator subjected to full load
The following measures are performed in sequence under the preconditions described:
