Check for self check codes 1st
Without starting engine, turn ignition on, off, on, off and on within 5 seconds. Record 2-digit Diagnostic Trouble Codes (DTCs) as displayed by flashing MIL.
For example, DTC 41 will be displayed by 4 flashes, short pause, and then one flash. A short pause will exist between first and second digits on DTC. If more than one DTC is stored, after first DTC is displayed, there will be a longer pause and then another stored DTC will be displayed.
