ALP 1 No dialogue with the computer
NOTESCheck the condition and connection of the battery connections (see 80A Battery).
Check the condition of the fuses.
Check the battery voltage (see 80A Battery).
Repair if necessary (see MR 411 Mechanical 80A Battery).
Switch on the + after ignition feed.
Connect the diagnostic tool and perform the required operations.
Connect the diagnostic tool to another vehicle to check that it establishes dialogue correctly with the
vehicle. If dialogue is established correctly.
Check the multiplex network of the faulty vehicle (see 88B Multiplexing).
Check the connection between the diagnostic tool and the diagnostic socket (connection and cable in good
condition),
the computer supplies and the engine and passenger compartment fuses.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check the presence and condition of fuse F11 (20 A) on the passenger compartment fuse and relay box
(component code 1016). Replace the fuse if necessary.
Check the condition and connection of the connector of component 225 (tabs bent, oxidised or broken).
Check for + 12 V battery feed on connection BP19 of component 225.
Check for earth on connection MAM (for right-hand drive vehicles) or MAN (for left-hand drive vehicles) of
component 225.
Check for + after ignition feed on connections AP43, BP15, BPT, BP6, BP13, BP19, SP2, SP15 of
component 645.
Check for + 12 V accessories feed on connections SP2 and SP15 of component 645.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
AFTER REPAIRCarry out a complete check using the diagnostic tool.

ALP 26 Accessories feed not activated
NOTESCheck the battery voltage (see 80A Battery).
Start the fault finding procedure with the ignition off and the vehicle locked.
When the vehicle is unlocked, the instrument panel should light up for a moment.
Otherwise, carry out fault finding on the multiplex network (see 88B, Multiplexing).
Check the operation of status ET239 "Ignition switch position".
Check the presence and condition of fuses F27 (5 A), depending on the equipment, and F29 (15 A) on the
passenger compartment fuse and relay box (component code 1016).
Replace the fuse if necessary.
Check the condition and connection of the connectors of components 645 and 1016 (tabs bent, oxidised or
broken).
Check for + accessories feed on connection SP2 (for vehicles fitted with a manual gearbox) or SP15 (for
vehicles fitted with a sequential gearbox) of component 645.
Check for earth on connection NAM of component 645.
Check for earth on the connection MAM (for right-hand drive vehicles) or MAN (for left-hand drive vehicles) of
component 645.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check the insulation, continuity and the absence of interference resistance of the following connections:
Connection code SP2 between components 645 and 1016.
Connection code SP15 between components 645 and 1016.
Connection code MAN or MAM between component 645 and earth MAN or MAM (depending on the driving
layout; right-hand or left-hand drive).
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the fault is still present, contact the Techline.
AFTER REPAIRCarry out a complete check using the diagnostic tool.

jammed
NOTESCheck the battery voltage (see 80A Battery).
Check for faults using the diagnostic tool. Deal with the other faults first.
The + accessories feed activation function should be working; if not deal with ALP 26
Accessories feed not activated first.
Make sure that status ET239 Ignition switch position is working.
Make sure that status ET239 Ignition switch position
is workingApply the interpretation of the status if necessary.
Run a multiplex network test (see 88B, Multiplexing).
See 13B, Diesel injection or see 17B, Petrol injection.

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.
