Haultronic II TroubleshootingPRESSURE TRANSDUCER FAULT

TROUBLESHOOTING STEPS:

2. Use the arrow keys to move to the STRUTS screen to check for opencircuit errors. These will be displayed as "ER ".

3. Unplug the right rear pressure transducer connector CN140 at the strutand verify supply voltage. Measure the voltage from pin A to pin B. See thechart below for transducer pin-out. The voltage should be 24 V 10%.


22/42



4. If the voltage is not within this range, then check the sensor supply voltageat the Contronic ECU between pin EB4 and ground "31EA". Ground for theright rear transducer is referenced at pin FB18. This is regulated 24Vdc tothe sensors and should be 24 V 10%.

6. The transducers have a pressure range of 0 to 10,000 psi. For thispressure range, the input voltage should be in the range of approximately0.95V to 4.76V. Ground Reference is pin EC19. If the voltage is not in this

range try plugging in another transducer.7. Plug a replacement transducer in the harness connector CN140 at the

right rear strut. The LCD screen will display a low pressure value 103 206kPa (15 to 30 psi) and the error will go away if the pressure transducerwas faulty

5. Check the input voltage at pin EC10 of the ECU for the Right Rearpressure transducer. The other pressure transducer inputs are given belowfor reference.


24/42



9. If the display still shows the open circuit condition, check the harness foropen or short circuit conditions. Repair or replace harness as necessary.

10.Check the circuit board traces for open or short circuit conditions. Replacethe circuit board if trace damage is found.

11.If no open or shorts are found, replace the ECU.

8. Replace the failed strut pressure transducer. Check the strut for proper X2dimension and gas charge.

Refer to Group 7 of the appropriate Service Manual.

Haultronic II TroubleshootingINCLINOMETER FAULT (Incline X Error)


The inclinometer measures 6 in the X (left to right) direction and 6 in the Y(uphill and downhill) direction, which is then displayed as a percent grade bythe following formula:

Grade (%) = 1.75 * Degree

The inclinometer connector pin arrangement and corresponding ECU/CircuitBoard pin numbers are given here for reference.

An example incline error in the X (left to right) direction is shown below. Theerror message will flash in the first row of the display.

1. Use the arrow keys to move to the STRUTS screen to check for open orshort circuit errors.

2. If the display reads" ERs ", disconnect the inclinometer.

If the error goes away, then the inclinometer has an internal short. Replacethe inclinometer.

If the display reads "ERo", go to STEP 7.

5. If the error remains, disconnect connector EC at the ECU. If the error goesaway (LCD should now read "ERo "), there is a short in the harness. Repairor replace as necessary.

6. If the " ERs" error remains, with connector EC disconnected, replace theECU.

7. If the display reads" ERo ", check the harness for open circuits between theinclinometer and the circuit board and from the circuit board to the ECU.Repair or replace the harness as necessary.

8. If no open circuits are found, check for shorts to 5V or possibly 24V at theinclinometer pin 3, circuit board pin CR4 and EZ32, and ECU pin EC32.

9. Also check the circuit board for an open trace between EZ32 and CR4. If

any open circuits are found, replace the board.

10.If the "ERo" error remains, replace the inclinometer.

11.If the "ERo" error remains, replace the ECU.

3. If the relay is OK, check the harness wiring and circuit board traces for

open or short circuits. Repair or replace the harness as necessary. Replacethe circuit board if any trace damage is found.

NOTE: Be sure to determine the cause of any circuit board trace failuresbefore replacing the circuit board.

TROUBLESHOOTING STEPS:1. Check the light wiring as well as the frame harness wiring to determine if

they are wired correctly. The load weigh lights are 24 V LED lights and arewired to the table below.

NOTE: Pin C (high intensity output) is always for loadweigh lightapplications for maximum visibility. Pin B (low intensity output) shouldnot be connected.

2. If the lights are wired correctly, remove the lens to check that the properlens has been installed. The lens or lenses may have been accidentallyswitched during assembly. The lenses are color matched to the LED light.(green lens with green LED light etc.).

3. If the lights still appear dim, check the voltage between pin C and pin A.The voltage should be at least 24V. The LED lights will be brighter withhigher voltage such as when the hauler is running. At this time, the voltagemay be 27.5 to 28 V.

4. Check the light connector pins for moisture or corrosion. Clean ifnecessary.
