Fault finding - Fault finding charts
ALP 6 No heating or inadequate heating
NOTESCarry out these checks after a full check using the diagnostic tool (fault reading and
configuration checks).
Check that the fuses are sound.
Use a multimeter, current clamp and 21 W test light.
Use the Wiring Diagrams Technical Note, NEW TWINGO.
Is the air flow correct?
YES
Is the air distribution correct?
YES
With a warm engine, set the heating to max.
Is the blown air hot?
NO
Using the parameter and statuses screen on the
diagnostic tool (Heating and UCH or Climate
Control sub-functions: 62B), check that the
temperature signals are consistent (no sensor
deviation resulting in incorrect measurement).
For manual air conditioning systems:
–Use parameters PR002 Exterior temperature
(depending on option) and PR024 Engine
coolant temperature.
For climate control systems:
–Use parameters PR002 Exterior
temperature, PR004 Coolant temperature
and PR001 Interior temperature.
Are the temperature signals consistent?
YES
NOSee ALP3 Air flow fault, air flow fault.
NOSee ALP2 Air distribution fault, air
distribution fault.
YESIf necessary, explain how the system works to
the customer again.
Carry out a conformity check:
–For the coolant temperature sensor,
see 13B, Diesel injection, Fault
summary table or 17B Petrol injection,
Fault summary table.
–For the exterior temperature sensor,
see 87B, Passenger compartment
connection unit, Fault summary table.
–For the interior temperature sensor,
see 62B, Climate control, Fault summary
table.
Replace any faulty components.

ALP 7 Too much hot air
NOTESCarry out this conformity check after a full check using the diagnostic tool
(fault reading and configuration checks).
Check that the fuses are sound.
Use a multimeter and a 21 W test light.
Use the Wiring Diagrams Technical Note, NEW TWINGO.
Is the air flow correct?
YES
Is the air distribution correct?
YES
Using the diagnostic tool statuses and
parameters screen (cold loop sub-function),
check that the temperature signals are
consistent (no sensor drift resulting in incorrect
measurement).
For manual air conditioning systems:
–Use parameters PR002 Exterior temperature
(depending on version) and PR024 Engine
coolant temperature.
For climate control systems:
–Use parameters PR002 Exterior
temperature, PR004 Coolant temperature
and PR001 Interior temperature.
Are the temperature signals consistent?
YES
NOSee ALP3, Air flow fault
NOSee ALP2, Air distribution fault.
