| Diagnosis and Testing Refer to Wiring Diagrams Section 413-01, for schematic and connector information. Special Tool(s) | | 73III Automotive Meter 105-R0057 or equivalent | | | Instrument Gauge System Tester 014-R1063 or equivalent | | | Worldwide Diagnostic System (WDS) 418-F224 or equivalent diagnostic tool | Principles of Operation The instrument cluster (IC) is a hybrid electronic cluster (HEC). The instrument cluster uses both hard-wired and the standard corporate protocol (SCP) (J1850) line to transmit and receive information. As a technician it is very important to understand: - where the input originates from.
- all information necessary in order for a feature to operate.
- which module(s) receive(s) the input or command message.
- does the module which received the input control the output of the feature, or does it output a message over the SCP (J1850) line to another module?
- which module controls the output of the feature.
The instrument cluster prove-out verifies that all warning/indicator miniature bulbs and monitored systems are functioning correctly. When the ignition switch is in the ON position with the engine off, the following warning indicators will illuminate: - malfunction indicator lamp (MIL) (SERVICE ENGINE SOON)
- charging system indicator
- low oil pressure warning indicator
- anti-lock brake (ABS) warning indicator
- safety belt warning indicator (if equipped)
- air bag warning indicator
- brake warning indicator
- low fuel warning indicator
- theft indicator
- low coolant warning indicator (3.0L (4V) engine only)
- O/D OFF indicator
Gauge Indication Systems The gauge indication systems use air-core type gauges mounted in the instrument cluster. No adjustment, calibration, or maintenance is necessary for any of the gauges. The gauges cannot be installed separately. Instrument Cluster Replacement When installing a new instrument cluster installation contact the Instrument Cluster Program. Speedometer The instrument cluster receives the vehicle speed signal from the powertrain control module (PCM) via the SCP (J1850) line. If the instrument cluster receives no signal the speedometer will default to 0.0 km/h (0.0 mph). Odometer The vehicle is equipped with two odometers. The primary odometer shows cumulative distance. The second odometer is the trip and tenths odometer. Tachometer The tachometer is electrically operated and indicates engine speed in a range of 0 to 8,000 rpm. The tachometer receives the signal via the SCP (J1850) line from the PCM. If the rpm information sent to the instrument cluster is invalid or missing, the instrument cluster will default the tachometer to 0.0 rpm. Fuel Gauge The instrument cluster receives the fuel signal via hard-wired circuitry from the fuel pump module. The fuel pump module changes resistance according to the amount of fuel in the fuel tank and varies the current flow through the fuel gauge. A low resistance will result in a lower gauge indication, while a high resistance will result in a higher gauge indication. The fuel gauge is controlled by the instrument cluster microprocessor and varies the position according to data received from the fuel pump module. Temperature Gauge The instrument cluster receives the engine coolant temperature signal from the PCM via the SCP (J1850) line network and displays the information on the temperature gauge. If the instrument cluster receives no signal the temperature gauge will default to the COLD position. Low Oil Pressure Warning Indicator The low oil pressure warning indicator is hard-wired to the oil pressure switch and is identified by an oil can symbol on the instrument cluster. The oil pressure switch is a normally closed switch. When the engine is off or has no oil pressure the switch is closed, providing a ground path to turn on the light. When the engine is running and there is oil pressure present, the switch is opened and no ground is provided. Low Coolant Level Warning Indicator—3.0L (4V) Engine The low coolant level warning indicator illuminates when the instrument cluster receives a signal that the engine coolant is low. When the vehicle is parked, there is a two-second delay before the instrument cluster illuminates the low coolant indicator. When the vehicle is moving, there is a 25 second delay before the instrument cluster illuminates the low coolant indicator. Charging System Indicator On the 3.0L (4V) engine, the charging system indicator is hard-wired to the generator and illuminates when the generator output is insufficient to maintain the battery state of charge. On the 2.0L Zetec engine, the instrument cluster receives its signal from the PCM via the SCP (J1850) line. Air Bag Warning Indicator The air bag warning indicator is hard-wired to the restraint control module. When the supplemental restraint system (SRS) is operating correctly, the air bag warning indicator illuminates for approximately six seconds when the ignition switch is turned on. It only illuminates after starting if a malfunction is present in the SRS. Service Engine Soon Indicator When the ignition is in the ON position the bulb will prove out. During vehicle operation, the malfunction indicator lamp (MIL) illuminates when the PCM has detected a fault. If a fault is detected the PCM sends a signal to the instrument cluster via the SCP (J1850) line and turns on the MIL lamp. High Beam Indicator The high beam indicator is hard-wired to the steering column multifunction switch and illuminates when the headlamps are placed in the high beam position or the flash-to-pass position. Turn Indicator The RH or LH turn indicators are hard-wired to the steering column multifunction switch and illuminate intermittently relative to the position of the turn signal switch on the steering column. Brake Warning Indicator The brake system warning indicator has multiple functions. It illuminates when the parking brake is applied, when the brake fluid level is low or when a fault is detected in the anti-lock brake system (ABS). It utilizes both hard-wired circuitry and the instrument cluster microprocessor. The bulb prove-out occurs for approximately three seconds after placing the ignition in the RUN position. The brake warning indicator will go out following prove-out if the brake fluid level is correct, the parking brake is released, and no ABS fault is detected. Anti-Lock Brake Warning Indicator (ABS) (if equipped) The anti-lock brake warning indicator (ABS) illuminates when the anti-lock brake control module detects a fault in the system. If a fault is detected the anti-lock brake control module sends a signal to the instrument cluster via hard-wired circuitry and the instrument cluster illuminates the ABS warning indicator. Safety Belt Warning Indicator (if equipped) The safety belt warning indicator illuminates when the driver safety belt is not fastened. The driver safety belt switch (part of the retractor) is hard-wired to the instrument cluster and provides the input into the instrument cluster signaling when the safety belt is connected. The instrument cluster then illuminates the bulb depending on the safety belt retractor position. Theft Indicator—Europe The theft indicator located in the instrument cluster is hard-wired to the generic electronic control (GEM) module and is controlled via the SCP (J1850) line from the PCM. The theft lamp illuminates for three-seconds when the GEM module receives the second lock signal for the double lock feature. Theft Indicator—Rest of World The anti-theft indicator located in the instrument cluster is controlled by a signal sent via the SCP (J1850) line from the PCM. 4WD Indicator Lamp (if equipped) On vehicles equipped with the manual transaxle, the 4WD indicator is hard-wired to the differential lock solenoid 4WD switch and illuminates when 4-wheel drive is selected. On vehicles equipped with the automatic transaxle, the 4WD indicator is hard-wired to the 4WD module and illuminates when 4-wheel drive is selected. Speed Control Indicator (if equipped) The speed control indicator is hard-wired to the speed control module and illuminates when the speed control is switched on. Front Fog Lamp Indicator (if equipped) The front fog lamp indicator is hard-wired to the fog lamp relay and illuminates when the fog lamps are turned on. Rear Fog Lamp Indicator (if equipped) The rear fog lamp indicator is controlled by the instrument cluster microprocessor. When the rear fog lamp switch is placed in the ON position, an input ground signal is provided to the instrument cluster microprocessor and the instrument cluster illuminates the rear fog lamp indicator. Door Ajar Indicator The door ajar indicator is hard-wired to the generic electronic module (GEM) and will illuminate when any of the doors, or the liftgate, are opened. Low Fuel Warning Indicator The low fuel warning indicator proves out for three seconds when the ignition is placed in the RUN position. The indicator will then remain on if the fuel level is less than approximately three gallons. O/D OFF Indicator (if equipped) The O/D OFF indicator will illuminate when the transmission overdrive has been turned off. The instrument cluster receives a switch status signal via the SCP (J1850) line from the PCM. PRND21 Indicator (automatic transaxle only) The instrument cluster PRND21 indicator is a liquid crystal display (LCD) that displays the transmission range selected. Two sets of input signals are necessary for the indicator to operate correctly. The instrument cluster receives the transmission range signal via hard-wired circuitry from the transmission range selector and displays the appropriate range in the LCD. The park interlock solenoid provides the second input signal. If the park interlock input is not present, the P range will not be highlighted in the LCD display. Inspection and Verification - Verify the customer concern by operating the system.
