GLOW INDICATOR LIGHT [SKYACTIV-D 2.2]
id0140z7265300
Purpose, Function
• The glow indicator light alerts the driver that the engine cannot be started by preheating the glow plug. In addition, it notifies vehicle servicing personnel of the operation condition during learning/data reset necessary with servicing.
Construction
• The glow indicator light is equipped in the instrument cluster.
Operation
• The glow indicator light illumination conditions are as follows:
Glow indicator light illumination conditions
-
― During preheating of glow plug before engine start when cold (during preheating timer operation)
― After ignition is switched ON (burnt out bulb check)
― During fuel injection learning (manual)
― Fuel injection learning (manual) is performed, however learning condition is not met
― During timing chain learning
Glow indicator light flashing conditions
-
― Fuel injection learning (manual) completed
― Fuel injection learning (manual) failed (continues to flash)
― Engine oil data reset completed
― Timing chain learning completed
• The PCM sends a glow indicator light illumination request to the instrument cluster via CAN communication.
Operation
1. The instrument cluster receives (1) the glow indicator light request signal from the PCM.
2. The instrument cluster microcomputer turns the transistor on (2) based on the glow indicator light request signal.
3. When the transistor turns on, a ground circuit with the glow indicator light is established and the glow indicator light illuminates (3).
Fail-safe
• Not applicable
