DIAGNOSIS CODE CHART
M1355001101277
CAUTION
During diagnosis, a diagnosis code associated
with other system may be set when the ignition
switch is turned on with connector(s) discon-
nected. On completion, confirm all systems for
diagnosis code(s). If diagnosis code(s) are set,
erase them all.
Follow the inspection chart that is appropriate for the
diagnosis code.
