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.
