ENGINE COMPARTMENT NODE (ECN)

The Engine Compartment Node is a microcomputer controlled unit which, informs the EVIC overhead console via the CCD bus of:

²Outside temperature

²Compass direction

and the following warning messages:

²Low Brake Fluid

²Low Coolant Level

²Low Engine Oil Level

The Engine Compartment Node is located behind the grill.

For complete diagnostic procedures for the Engine Compartment Node, refer to the Body Diagnostic Test Procedure Manual.

The compass direction displayed will be part of the overhead console.

If the engine compartment node is present without the overhead console, the EVIC display of the:

²Compass direction

²Ambient temperature

²Brake fluid level

²Coolant fluid level

²Engine oil level

The messages will be send by the ECN.

ECN COMPASS CALIBRATION

Automatic or Manual Calibration, refer to AY Body Compass Calibration.

THERMOMETER AND COMPASS

OPERATION

The ignition switch must be in the ON or ACCESSORY position before the temperature and compass reading can be displayed. The COMP/TEMP switch turns the compass display on and off. The US/Metric switch changes the temperature reading from Fahrenheit to Celsius (Fig. 2).

When the vehicle is standing still, engine compartment temperatures may be radiated to the temperature sensor. Therefore the most accurate ambient temperature readings are displayed when the vehicle is moving in a forward motion.

When the ignition switch is in the ON position the temperature display is updated every 5 minutes. When the ignition switch is turned off the last displayed temperature reading stays in memory. When the ignition switch is turned on again the thermometer will display the memory temperature for 1 minute; then update the display to the actual temperature within 5 minutes.

COMPASS CALIBRATION

Do not attempt to set the compass near large metal objects, such as, other vehicles, large buildings, or bridges.

The compass unit automatically calibrates itself as the vehicle is driven; therefore, no calibration should be required. When the compass is first powered up, the CAL light on the display should be on. The CAL light will go off and the compass will be accurate after the vehicle completes 1 to 3 complete circles.

If the vehicle's compass headings are inaccurate, the compass also can be manually calibrated using the following procedures:

(1)Depress and hold down both the Comp/Temp button and the U.S./Metric button.

(2)The display will go off and after 5 seconds the VAR light will come on. Continue to hold both buttons down.

(3)In approximately 10 seconds, the CAL light will come on. Release both buttons and the display will show the heading and outside temperature.

(4)Drive the vehicle 1 to 3 complete circles. The CAL light will then go off, showing the compass is calibrated.

If the compass portion of the display:

²It does not display.

²Readings are not accurate after calibration.

²The vehicle may have too much magnetism for the compass to be accurate.

²The compass circuitry is not working properly.

²Refer to Variance Procedure, Demagnetizing Procedure and/or Compass Diagnostics.

VARIANCE PROCEDURE

Variance is the difference between magnetic North and geographic North. In some areas the difference between magnetic and geographic North is great enough to cause the compass to give false readings. If this occurs, the variance must be set.

To set the variance, depress and hold down both the Comp/Temp button and the U.S./Metric button.

8C - 14 OVERHEAD CONSOLE

The display will go off and after 5 seconds the VAR light will come on. Release both buttons. Using the zone map (Fig. 3) to find your geographic location, note the zone which, you are in. Press the U.S./Metric button until the zone number appears on the display. Press the Comp/Temp button to enter your zone number.

Fig. 3 Variance Zone Map

Do not attach magnetic devices, such as magnetic CB antennas to the vehicle roof, as they can cause the compass to give false readings.

DEMAGNETIZING PROCEDURE

Every vehicle has its own magnetic field. This magnetic field is created by the various processes a steel roof goes through when the vehicle is built. A magnetic field also can be created if the roof is subjected to a magnet, example:

²Magnetic c.b. antenna

²Magnetic tipped screwdriver and etc.

If the roof becomes magnetized use a demagnetizer tool 6029 to demagnetize the roof.

In this demagnetizing procedure you will use the demagnetizing tool to demagnetize the roof and mounting screws in the overhead console. It is important that you follow the instructions below exactly. The mounting screws and the mounting brackets around the compass area are steel, and therefore aid in the demagnetizing of the roof panel.

Ä

(1)Be sure the ignition switch is in the OFF position before you begin the demagnetize procedure.

(2)Open the sun glass compartment to gain access to the overhead console mounting screws.

(3)Plug the demagnetizing tool into a standard 110/115 volt AC outlet, keeping the demagnetizing tool at least 12 inches away from the compass area when plugging it in.

(4)Slowly approach the console mounting screw with the plastic coated tip of the tool for at least 2 seconds.

(5)With the demagnetizing tool still energized, slowly back it away from the screw until the tip is at least 12 inches from the screw head.

(6)After you have pulled at least 12 inches from the last screw, remove the demagnetizing tool from inside of the vehicle and disconnect it from the electrical outlet.

(7)Place an 8 1/2 X 11 inch piece of paper lengthwise on the roof of vehicle directly above compass. The purpose of the paper is to protect the roof panel from scratches and define the area to be demagnetized.

(8)Plug in the demagnetizing tool, keeping it at least 2 feet away from the compass unit.

(9)Slowly approach the center of the roof panel at the windshield with the demagnetizing tool plugged in.

(10)Contact the roof panel with the tip of the tool. Using slow sweeping motions of 1/2 inch between sweeps. Move the tool approximately 4 inches either side of the centerline and at least 11 inch back from the windshield.

(11)With the demagnetizing tool still energized, slowly back away from the roof panel until the tip is at least 2 feet from the roof before unplugging the tool.

(12)Recalibrate compass.

COMPASS DIAGNOSTICS

To place the unit into the diagnostics mode, turn the vehicle ignition off. Depress the Comp/Temp button while turning on the ignition/run switch. The display will then show DO. There are 3 tests that can be performed when in the diagnostics mode. Press the U.S./Metric button to choose test desired (Fig. 4 and 5).

Test 1 (d1) determines the magnetic field strength at the compass. The compass displays compensation numbers which, correspond to the current magnetic field strength at the compass. The letter N is displayed in the compass portion of the display. While a number which, corresponds to the magnetic field strength in the North/South direction is displayed. The temperature portion of the display or the letter W is displayed in the compass portion of the display. A number which, corresponds to the magnetic field strength in the East/West direction is displayed in
