| (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 only if no "NE" signal is sent to ECM with engine at approximately 1500 RPM. (3) The MIL will be illuminated only if no "G" signal is sent to ECM at least 4 times when engine speed is between 500 and 4000 RPM. (4) Applies only to models with electronic-controlled automatic transaxle. |
