FAULT DIAGNOSIS

MEMORY SEAT CONTROLLER (MSC)

OPERATION OF DIAGNOSTICS:

The memory seat controller (MSC) stores specific fault codes
for all functions of the (MSC). The diagnostics are specifically
used to identify faults within the seat assembly, and as such will
hinder the operation of the seat.
When a fault is detected in the (MSC), the system will automat-
ically enter into diagnostic mode.
The indicator lamp (LED) will begin to flash in certain sequence
to indicate a diagnostic trouble code (DTC) as shown in the
table below. The indicator lamp (LED) will stop flashing when
the faults have been resolved.

DIAGNOSTIC TROUBLE CODES (DTC’s)

The indicator lamp (LED) transmits a certain sequence flash to
distinguish faults.The DTC sequence for the most recent cur-
rent trouble is flashed twice only. If there are multiple faults
present, you can display the next current DTC by pressing the
memory button 2 before the MSC goes into the sub-active
mode. Once all DTC’s have been cycled through, the most
recent current DTC will be displayed. There will be no history of
DTC’s displayed.
