Check leads between control unit
and diagnostic jack
– Connect the test lead, b 7.3.2
: Measure the resistance between
red lead (1) and black plug (2) of
the diagnostic cable
Target value: < 10 ohms.
: Measure the resistance between
black lead (1) and red plug (2) of
the diagnostic cable
Target value: < 10 ohms.
If the target values are not
attained
– Check that screw on control unit
(ignition module) and screw on
angled terminal socket are firmly

– Check continuity between blade
receptacle and angled terminal
socket
– Blade receptacle and angled
terminal socket must be firmly
connected with one another; in
the event of contact problems,
the M-Tronic wiring harness must
be replaced, b 7.4.
Check leads between solenoid
valve and diagnostic jack
– Connect the test lead, b 7.3.2
: Disconnect the plug (1) from the
solenoid valve (2)
: Measure the resistance between
red lead (1) at the plug of the
solenoid and black plug (2) of the
diagnostic cable
Target value: < 10 ohms

: Measure the resistance between
black lead (1) at the plug of the
solenoid and red plug (2) of the
diagnostic cable
Target value: < 10 ohms
If the target values are not
attained
– Check contact surfaces between
lug and screw and check leads
for interruptions, e. g., cable
breakage – the leads must be
firmly seated in the blade
receptacle and in the lug.
