Retrieving Codes

Use Mode II to retrieve trouble codes. Read codes using either Malfunction Indicator Light (MIL) or Red LED inspection light on ECM. Trouble codes will flash after selecting Mode II.

Trouble codes are indicated by number of flashes from MIL or Red LED inspection light. For example, 3 long (.6 second) flashes followed by 2 short (.3 second) flashes of MIL or Red LED indicate a Code 32. There will be a .9 second pause between long and short flash groups. There will be a 2.1 second pause between codes.
