Up-Shift Indicator Lamp

1987 Jeep Cherokee LimitedSECTION Up-Shift Indicator Lamp

Manual transaxle vehicles are equipped with an up-shift indicator lamp. The lamp is normally turned on when the ignition switch is turned "ON", and is turned off when the engine starts.

The lamp will again light during engine operation, according to engine speed and load conditions. A switch, located on the transaxle, prevents lamp from lighting when transmission is shifted to the next highest gear. If the shift of gears is not performed, the ECU will turn the lamp off after 3-5 seconds.
