ALP 28 Illumination of the "battery charge" warning light
NOTESCheck the battery voltage (see 80A Battery).
Check for faults using the diagnostic tool.
Deal with the other faults first.
Check with LC023 Engine type that the engine type configured matches the vehicle. Otherwise perform CF028
Engine type to modify the configuration.
IMPORTANT
The battery warning light can flash if a low battery charge is detected (no-load voltage less than 12.2 V: voltage
measured during technical use) for the first 12 miles (20 km), then the warning light stops flashing. Also, the magic
eye of the battery (the hydrometer) is black.
If a vehicle has been driven less than 12 miles (20 km), the battery warning light is flashing and the battery magic
eye (the hydrometer) is black, apply the following procedure:
-Recharge the battery for at least 6 hours. The battery must be disconnected (reconnection must be done to torque).
Note:
The battery must be recharged using a specific charger, which is listed in the "Garage Equipment" catalogue.
-After 6 hours, if the magic eye has not turned green, the battery must be replaced.
If the configuration is correct (see 80A Battery).
If the fault is still present, contact the Techline.
AFTER REPAIRCarry out a complete check using the diagnostic tool.

ALP 30 Low light intensity
NOTESCheck the battery voltage (see 80A Battery).
Check for faults using the diagnostic tool. Deal with the other faults first.
With the engine running at idle speed, run command AC130 Alternator regulation.
–Wait 20 seconds.
–For 10 seconds the voltage of the alternator (component code 103) should be equal to 15 V ± 0.2 V, when
using a multimeter to measure on connection BPDA between components 103 and 645.
–Wait 20 seconds.
–For 10 seconds the voltage of the alternator (component code 103) must be equal to 13 V ± 0.2 V when
measuring between the alternator terminal (component code103) and the earth on connection 2N using a
multimeter.
If the values measured are not correct, check the starting - charging circuit (see 16A Starting - Charging) and
check the battery (see 80A, Battery).
If the fault is still present, contact the Techline.
AFTER REPAIRCarry out a complete check using the diagnostic tool.

* SR.: Sunroof
ALP 31 The sunroof does not work
NOTESOnly consult this customer complaint after a complete check using the diagnostic
tool and after having applied the interpretation of DF065 Electric window
authorisation connection.
Check that nothing is obstructing the operation of the sunroof.
Repair if necessary.
Check the condition of fuses F26 (20 A) and F31 (30 A) in the passenger compartment fuse and relay box
(component code 1016).
Replace the fuse if necessary.
For vehicles equipped with a sunroof, check that the LC070 One-touch windows/SR* is With. Otherwise,
perform CF173 One-touch windows/SR*.
If CF173 One-touch windows/SR* is With, (see MR 411 Mechanical, 87D Electric windows - Sunroof).
AFTER REPAIRCarry out a complete check using the diagnostic tool.
