Notes On Codes

  1. No other code will appear with Code 11.
  2. When Codes 25, 26, 27 and 71 initially happen, they will be temporarily stored in ECU memory, but CHECK ENGINE light will not come on. The second time code is detected, CHECK ENGINE light will then come on. This is referred to as the 2 trip detection logic.
  3. When in Normal Mode, CHECK ENGINE light will go off once malfunction is repaired. Fault codes (except for Codes 16, 43, 51 and 53) will remain in ECU memory until codes are cleared.
  4. When in Test Mode, codes will remain in ECU memory as long as ignition remains on, even if malfunction is repaired (except for Codes 43, 51 and 53). Once ignition is turned off, codes will be erased from ECU memory. During Test Mode, if vehicle is not driven at a speed greater than 10 MPH, ECU will set a Code 42 and 43.
