DIAGNOSTIC TROUBLE CODE CHART
M1524003300528
CAUTION
During diagnosis, a DTC code associated with
another system may be set when the ignition
switch is turned on with connector(s) discon-
nected. After completing the repair, confirm all
systems for DTC code(s). If DTC code(s) are set,
erase them all.
Inspect according to the inspection chart that is
appropriate for the DTC.
