| (1) ON indicates MIL on instrument panel will be illuminated. N/A indicates item is not included in malfunction diagnosis when using this mode. OFF indicates MIL on instrument panel will not be illuminated even if malfunction is detected. (2) The MIL will be illuminated if "NE" signal does not pulse 12 times to ECM during interval between "G1" and "G2" pulses. (3) The MIL will be illuminated if no "NE" signal to ECM is received with engine at 1000 RPM or if deviation in "G", "G1", "G2" or "NE" signal exists during idling with engine warm. (4) Applies only to models with electronic-controlled automatic transaxle. (5) The MIL will be illuminated if problem exists in oxygen sensor circuit. The MIL will not be illuminated if problem exists in oxygen sensor heater or circuit. |
