Diagnosis - Diagnostic Trouble Code (DTC) Memory

Diagnosis
Limit switch diagnostic trouble codes (DTC's) are only stored when the soft
top stops moving during soft top operation and the switch is held depressed
until the indicator lamp begins blinking. The exceptions are the switches
for roll bar extended and roll bar retracted where the indicator lamp in
the roll bar switch lights. DTC's 5 - 16 are considered limit switch DTC's,
which do not necessarily mean the respective switch is defective, but rather
should be interpreted as an indication of which limit switch signals are
absent and are needed for the sequence to continue.
Possible causes:
 Electrical fault (the last soft
top or roll bar movement requested was completed).
Hydraulic fault (the last soft top
or roll bar movement requested, did not occur). |
