If the engine temperature gauge operates correctly, INSTALL a new instrument cluster. REFER to INSTRUMENT CLUSTER article. TEST the system for normal operation. If the engine temperature gauge does not operate correctly, REFER to INSTRUMENT CLUSTER article to continue diagnosis of the engine temperature gauge.
The high engine temperature, high engine temperature with performance reduced, and high engine temperature with stop engine safely warning is inoperative (Hybrid)	Circuitry ECT sensor PCM Instrument cluster	CHECK if the overtemp warning indicator is illuminated. If the overtemp warning indicator is illuminated, INSTALL a new instrument cluster. REFER to INSTRUMENT CLUSTER article. TEST the system for normal operation. If the overtemp warning indicator is not illuminated, RETRIEVE the PCM DTCs. If PCM DTCs are retrieved, REFER to the Introduction - Gasoline Engines article to continue diagnosis. If no PCM DTCs are retrieved, INSTALL a new instrument cluster. REFER to INSTRUMENT CLUSTER article. TEST the system for normal operation.
The SERVICE 4x4 warning is inoperative (Escape, Mariner)	Four-wheel drive (4WD) system	REFER to FOUR WHEEL DRIVE (4WD) SYSTEMS article to continue diagnosis of the 4WD system.
The PARK BRAKE ON warning is inoperative	Circuitry Parking brake switch SJB Instrument cluster	CHECK the operation of the brake warning indicator. If the brake warning indicator operates correctly, INSTALL a new instrument cluster. REFER to INSTRUMENT CLUSTER article. TEST the system for normal operation. If the brake warning indicator does not operate correctly, REFER to INSTRUMENT CLUSTER article to continue diagnosis of the brake warning indicator.
The LOW BRAKE FLUID warning is inoperative	Circuitry Anti-lock brake system (ABS) module Instrument cluster	CHECK the operation of the brake warning indicator. If the brake warning indicator operates correctly, INSTALL a new instrument cluster. REFER to INSTRUMENT CLUSTER article. TEST the system for normal operation. If the brake warning indicator does not operate correctly, REFER to INSTRUMENT CLUSTER article to continue diagnosis of the brake warning indicator.
The door ajar warning is inoperative	Door ajar switch SJB Instrument cluster	TURN the ignition switch to the ON position and CHECK the operation of the interior lamps. If the interior lamps operate correctly, INSTALL a new instrument cluster. REFER to INSTRUMENT CLUSTER article. TEST the system for normal operation. If the interior lamps do not operate correctly, REFER to INTERIOR LIGHTING article to continue diagnosis of the interior lamps.
The LOW FUEL level warning is inoperative	Circuitry Instrument cluster	CHECK the operation of the fuel gauge. If the fuel gauge operates correctly, INSTALL a new instrument cluster. REFER to INSTRUMENT CLUSTER article. TEST the system for normal operation. If the fuel gauge does not operate correctly, REFER to INSTRUMENT CLUSTER article to continue diagnosis of the fuel gauge.
The check exterior lamps warning is inoperative	SJB Instrument cluster	VERIFY that the SJB is correctly configured for the lamp outage. REFER to MODULE CONFIGURATION article. CHECK the operation of the exterior lamps. If all of the exterior lamps operate correctly, INSTALL a new instrument cluster. REFER to INSTRUMENT CLUSTER article. TEST the system for normal operation. If any exterior lamp does not operate correctly, REFER to EXTERIOR LIGHTING article to continue diagnosis of the exterior lamps.
The CHECK FUEL CAP warning is inoperative	PCM Instrument cluster	RETRIEVE the DTCs. If DTC U1900 is retrieved, REFER to MODULE COMMUNICATIONS NETWORK article to continue diagnosis of the communication network. If no DTCs are retrieved, INSTALL a new instrument cluster. REFER to INSTRUMENT CLUSTER article. TEST the system for normal operation.
The low tire monitor fault, or tire sensor fault warning is inoperative	Circuitry SJB Instrument cluster	OBSERVE the operation of the low tire pressure warning indicator. If the low tire pressure warning indicator operates correctly, INSTALL a new instrument cluster. REFER to INSTRUMENT CLUSTER article. TEST the system for normal operation. If the low tire pressure warning indicator does not operate correctly, REFER to INSTRUMENT CLUSTER article to continue diagnosis of the low tire pressure warning indicator.
