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.
