Clearing Codes

To erase codes, turn jumper switch on. After about 2.5 seconds there will be 3 short flashes. Immediately after third flash, turn jumper switch off.

Some faults can be classified as adaptation faults. Once the fault is corrected, the codes generated may not be erased until the system readapts to the new running conditions. See ECU ADAPTATION  .
