PR074BATTERY VOLTAGE
PARAMETER
DEFINITIONThis parameter indicates the battery voltage in Volts.
NOTESThere must be no present or stored faults.
Without electrical consumers (radio, air conditioning, fan assemblies, headlights,
etc.).
Conformity check: Engine stopped and ignition on, or engine running and engine coolant
temperature > 80
°C
12 V < PR074 < 14.4 V.
Ignition on then
at idle speedIf the voltage is at minimum:
Check the battery and the charge circuit (see 87B, Passenger compartment connection unit
for the New Twingo or see 87G, Engine compartment connection unit for Clio III, Modus,
Mégane II, Scénic II and Kangoo 2).
If the voltage is at maximum:
Check that the charging voltage is correct with and without electrical consumers switched on.

TEST 2 Electrical circuit check
Check the battery charge and that the alternator
is operating correctly (see 87B, Passenger
compartment connection unit for the New
Twingo or see 87G, Engine compartment
connection unit for Clio III, Modus, Mégane II,
Scénic II and Kangoo 2).
Is the charging circuit in good order? Carry out the necessary repairs.
Check the fuses.
Are the fuses correct? Carry out the necessary repairs.
Check that the injection locking relay is operating
correctly.
Is the injection locking relay working properly? Carry out the necessary repairs.
Check the engine earths.
Are the engine earths correct? Carry out the necessary repairs.
The electrical circuit is in good order.

ALP1 No dialogue with the computer
NOTESOnly consult this customer complaint after a complete check with the diagnostic tool.
To check that the diagnostic tool is not causing the fault, try to establish dialogue with a computer on another
vehicle. If the diagnostic tool is not the cause and communication cannot be established with any other computer
on the same vehicle, it is possible that another computer is disrupting the multiplex network. Check the battery
voltage and make the necessary adjustments to obtain a correct voltage (9.5 V < Battery voltage < 17.5 V).
Run fault finding on the multiplex network using the diagnostic tool (see 88B, Multiplexing).
Check the presence and the condition of the injection fuses on the UPC and on the engine fuse box.
Check the connection of the computer connectors and the condition of its connections.
Check the injection computer earths (quality, oxidation, earth bolts secure on the battery terminal).
Check that the supply to the computer is correct:
For New Twingo:
–AP29 between components 1016 and 120,
–3FB between components 238 and 120,
–NH between earth and component 120,
For Mégane II, Scénic II, Modus, and Clio III:
–AP15 between components 1337 and 120,
–NH between earth and component 120,
–3FB1 between components 1337 and 120,
–3FB2 between components 1337 and 120.
For Kangoo 2:
–AP15 between components 1337 and 120,
–N between earth and component 120,
–3FB between components 1337 and 120,
–3FB1 between components 1337 and 120,
–3FB2 between components 1337 and 120.
Ensure that the supply to the diagnostic socket is correct:
–BP32 between components 225 and 260,
–AP43 between components 225 and 1337,
–MN between earth and component 225.
If dialogue has still not been established after these checks, contact Techline.
