Check for 12 V on relay 232 between
connection 1A of component 232 and a
chassis earth when starting is requested.
Is there 12 V?Replace the starter relay (see MR 411
Mechanical, 81C, FUSES, Engine
compartment fuse and relay box: List and
location of components).
Continuity and/or insulation fault on
connection 1A between components 232 and
163. If there is a repair method (see Technical
Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair) repair the
wiring, otherwise replace it.

ALP2 The starter turns but does not engage
NOTESSpecial notes:
Disconnect the battery earth before handling.
Remove the starter (see MR 411 Mechanical, 16A, Starter: Removal - Refitting).
Check that the ring gear of the flywheel is in good condition.
Are the ring gear teeth damaged?
Replace the flywheel (see MR 411, Mechanical, 10A,
Flywheel: Removal - Refitting).
Check the condition of the starter (broken teeth or
worn gears).
Is the starter in good condition?
Replace the starter (see MR 411
Mechanical, 16A, Starter: Removal -
Refitting).
Refit the starter (see MR 411 Mechanical, 16A,

ALP3 The starter is noisy when starting
NOTESTest the condition of the battery (see MR 413, 80A, Battery).
Check that the noise is actually coming from the starter.
Try to start the engine.
At what point is the noise heard?
Starting phase Just after the engine has started
Check if the starter is
insufficiently secured
Is the starter correctly secured?Tighten the starter mountings (see MR 411, 16A,
Starter: Removal - Refitting).
Remove the starter and check that the centring
pin is present. Check the condition of the pinion
and check the entire ring gearInhibit the engine injection (see 13B or 17B,
Interpretation of commands), activate the
starter for 2 seconds and release the key.
Is a fault noticed?Does the starter continue to run after the key is
released?

Fit a centring pin, or replace the
flywheel (see MR 411,
Mechanical, 10A, Flywheel:
Removal - Refitting), or replace
the starter (see MR 411, 16A,
Starter: Removal - Refitting).Starter control fault, check the entire
starter control line (see ALP1
continued 3 "C").
Replace the starter (see MR 411, 16A Starter:
Removal - Refitting).
Make several attempts, waiting for 5 minutes
after 5 attempts (let the starter cool). If the result
is still the same after several attempts, replace
the starter (see MR 411, 16A, Starter:
Removal – Refitting).

ALP4The starter rotates slowly from the outset.
The rotation speed of the starter decreases rapidly.
The starter causes the warning lights on the instrument panel to
become very dim
Applicability: All types
NOTESTest the wiring (TEST3).
Test the status of the battery (see 80A, Battery).
If the fault is still present, replace the starter (see MR 411, 16A, Starting - Charging, Starter: Removal -
Refitting).

NOTESPerform this test only after running complete fault finding on the UCH using the
diagnostic tool (see 87B, UCH).
Because the UCH houses the CHARGING CIRCUIT function (sub-function: alternator)
and checks the alternator via a serial connection (BSS).

TEST1 Alternator supply test
NOTESTest the condition of the battery (see 80A, Battery).
Measure the voltage at the battery terminals with the engine warm and running at idle speed for 2 minutes and with
all consumers switched off.
Voltage value?
Replace the alternator (see MR 411, 16A, Starting - Charging,
Alternator: Removal - Refitting).
Visually inspect the consequences (battery condition, corrosion, etc.).
With the engine at idle speed, connect a current clamp to the alternator B+ wire, connection BPDA, with all
consumers switched off.
Current < 5 ACurrent between 5 A
and 35 ACurrent > 35A
Replace the alternator
(see MR 411, 16A, Starting -
Charging, Alternator:
Removal - Refitting).Keep the engine speed at
3000 rpm and still with no
consumers switched on.Check that there are no
electrical components
consuming an abnormal
amount of current.
Disconnect the fuses one by
one to identify the consumer.
To be examined Value of measured current?

TEST2 Test the condition of the power fuse and the cause of its fault
NOTESCheck that the engine is not locked
With the ignition off, measure the voltage between the negative
battery terminal and the power fuse output.
Is the voltage greater than or equal to 10V?
The power fuse is sound The power fuse is faulty
With the battery disconnected, measure the resistance between
the negative battery terminal and the power fuse output.
Is the resistance
≥ 10 Ohms?
Disconnect the alternator + terminal and
then measure the resistance between the
negative battery terminal and the power
fuse output.Possible external causes:
use of a "starter charger", excessively long
use of starter (e.g.: activate the starter, gear
engaged for driving the vehicle) etc.
Is the resistance
≥ 10 Ohms?

Check the wiring connecting the alternator and the
starter to the battery + terminal (see TEST 3).Replace the alternator (see MR 411, 16A,
Starting - Charging, Alternator: Removal -
Refitting).
Is it in good condition?
Replace the starter (see MR 411, 16A, Starting -
Charging, Starter: Removal - Refitting).
Repair the damaged wires and terminals. If the
connection is faulty and if there is a repair procedure
(see Technical Note 6015A, repairing electrical
wiring, wiring: Precautions for repair), repair the
wiring otherwise change the wiring.
Replace the power fuse (see MR 411, 80A, Battery, Battery: Removal - Refitting).
