Trouble codes are displayed by the malfunction indicator lamp (MIL). Some models: The ECM fault memory can also be checked using diagnostic equipment connected to the data link connector (DLC). Accessing Normal mode Switch ignition ON. Bridge data link connector (DLC) terminals El and TEI n. If no trouble codes are stored, the lamp will flash twice per second m. Each trouble code consists of two groups of one or more flashes El [A]. Warning lamp flash duration: 0,5 second [B]. A 0,5 second pause separates each flash El [C]. A 1,5 second pause separates each trouble code group El [Dl. A 2,5 second pause separates each trouble code [El. For example: Two 0,5 second flashes - 1,5 second pause - one 0,5 second flash. Trouble code 21 displayed El - heated oxygen sensor (H02S). Trouble codes are repeated 43 seconds after last trouble code. Count MIL flashes. Note trouble codes. Compare with trouble code table. Remove bridge wire. Switch ignition OFF. Rectify faults as necessary. ON OFF 95
