NOTESTest the condition of the battery (see 80A, Battery).
Test the condition of the power fuse (see TEST 2).
Check that fuse F9 on component 1016 is in good condition.
Check that the engine is not jammed.
Check that the following terminals are
correctly tightened:
⇒ the battery
⇒ starter
⇒ engine earth
⇒ bodywork earth
Retighten the terminals (see MR 411, 80A,
Battery, Battery: Removal - Refitting).
Are the terminals correctly tightened?
Check that the following wires are in good
condition:
⇒ the wire connecting the battery +,
component 107, to terminal B+ of the
starter, component 163,
⇒ the wire connecting the battery - to
the bodywork earth,
⇒ the wire connecting the engine to
the bodywork earth.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. Are the wires in good condition?
Try starting.

With the ignition switched off, measure the voltage between the battery earth and the starter control terminal.
Voltage value?
While activating the starter, measure the
voltage between the battery earth and the
starter control terminal.Disconnect the starter control terminal wire
and measure the voltage on the wire of
connection 1A again.

Use the diagnostic tool to check DEF 062 of
the starter relay control circuit (see 87B,
Passenger compartment connection unit,
Interpretation of faults).
Is the fault present?Fault on connection 1B between components
597 and 645 (see 87B, Passenger
compartment connection unit,
Interpretation of faults). If there is a repair
method (see Technical Note 6015A,
Repairing electrical wiring, Wiring:
Precautions for repair) repair the wiring,
otherwise replace it.
Check the starting conditions (see 87B,
Passenger compartment connection unit,
Interpretation of statuses).
Is ET046 immobiliser active?Starting conditions fault (see 87B, UCH,
Interpretation of statuses).
With the ignition on, check for 12 V between
connections AP29 and 1B of the relay
connector, component 232, located on the
engine relay box, component 597.
Is there 12 V?Check the continuity and/or the insulation of
connections 1B between components 232 and
645, or of connection AP29 of components 232
and 1016.
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.
Check for 12 V on relay 232 between
connection D of component 232 and a chassis
earth when starting is requested.
Is there 12 V?Check the continuity and/or the insulation of
connection D between components 232
and 104.
If the connection is faulty and if there is a repair
procedure (see Technical Note 6015A,
