1) Combined instrument panel warning lamp. When a fault occurs the diagnostic trouble code (DTC) is stored and after a set interval the warning lamp begins to flash. If the fault is intermittent and disappears, the warning lamp will go out after the ignition has been switched on and off a number of times, but the diagnostic trouble code (DTC) persists. The diagnostic trouble code (DTC) should be checked.
2) Malfunction indicator lamp (MIL) comes on. Only USA/CDN
3) Only while the temperature remains high.
4)When a fault occurs the combined instrument panel warning lamp flashes once.
5) The warning lamp in the combined instrument panel flashes. Activates Malfunction Indicator Lamp (MIL). Only USA and Canada 1997 model year.-
6) Activates malfunction indicator lamp (MIL). Only USA and Canada 1997 model year.-
