Engine Information/Diagnostic Indicator (Caution Lamp)

When a problem develops that may reduce engine performance, information indicator light will come on and a steady alarm will sound for three seconds.

When indicator comes on, engine is entering self-protection de-rate mode. Reduce engine load and promptly determine cause.

Engine performance may be reduced by the following conditions:

  • High fuel temperature
  • High charge air temperature
  • High engine coolant temperature

(To test indicator light bulb for proper operation, see Indicator Display Panel Bulb Check in this section).
