STOREDAUTOMATIC TRANSMISSION MULTIPLEX SIGNAL
1.DEF: No multiplex frameworks or invalid values (signal producing computer fault
or multiplex line connection fault).
NOTESConditions for applying fault finding procedures to stored faults:
The fault appears after:
–No signals transmitted over the multiplex line network.
System effects:
Engine does not start.
No lever position display on the instrument panel.
Note: the effects of the fault disappear as soon as signals start transmitting again over
the multiplex network.
Customer complaint:
Engine does not start.
No lever position display on the instrument panel.
Jolting during gear changes.
Note: the effects of the fault disappear as soon as signals start transmitting again over
the multiplex network.
Use the Wiring Diagrams Technical Note, SCENIC II ph2.
Run a multiplex network test (see 88B, Multiplex).
Check the continuity and insulation against earth of the following connections:
●Connection code 3MS.
●Connection code 3MT.
between components 119 and 129.
If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition, wait 1 minute and carry out a road test followed by another
check with the diagnostic tool.

STOREDABS MULTIPLEX SIGNAL
1.DEF: No multiplex frameworks or invalid values (signal producing computer
problem or multiplex line connection fault).
NOTESSystem effects:
The lock-up is inhibited (still open).
Customer complaint:
If the lever is in position "P", the "Apply brake" icon is not displayed on the instrument
panel.
The function reducing drag when stationary is no longer operational.
Use the Wiring Diagrams Technical Note, SCENIC II ph2.
Run a multiplex network test (see 88B, Multiplex).
Run a check on the ABS anti-lock braking system (see 38C, ABS Bosch 8.0).
Check the continuity and insulation against earth of the following connections:
●Connection code 3MS,
●Connection code 3MT,
between components 119 and 120.
If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the fault is still present, contact the Techline.
