Introduction Diagnostic Procedure Follow the flowchart below for all Bendix™ VORAD® system failures. Perform the tests and procedures as directed by the flowchart. Key On Is the Operator Display Unit lamp lit? NO • Perform Electrical Pretest (page 2-1) • Perform Power-up Sequence Test (page 2-5) YES Is Driver YES Experiencing System Problems? NO Test Complete.
Fault Isolation Procedures Electrical Pretest Overview Required Tools The pretest verifies the basic electrical inputs before testing individual circuits. Detection Fallback There is no fallback for the electrical pretest, however, it may affect other systems.
Fault Isolation Procedures Electrical Pretest Step A Procedure Condition Action 1. Key off. 2. Inspect starter/battery connections for integrity. 3. Measure voltage across battery. If voltage is 11 to 13 volts on a 12 volt system or 22 to 26 on a 24 volt system If voltage is outside of range Go to Step B. Repair or replace batteries and charging system as required. Repeat this step. VOLT V Step B COM A Procedure Condition Action 1. Key off. 2. Disconnect negative (-) battery cable. 3.
Fault Isolation Procedures Electrical Pretest, continued Step C Procedure Condition Action 1. Key off. 2. Connect negative (-) battery cable. 3. Key on. If voltage is within .5 volts of battery voltage Test complete. If voltage is outside of range Repair power path to system. Fuse may be blown. Reconnect all connectors. Go to Step A. Electrical Pretest 4. Measure voltage between sensor harness J2 pin 1 and ground.
Fault Isolation Procedures Power-Up Sequence Test Overview Required Tools The failure during the power-up self-check indicates a system failure. • Digital Volt/Ohm Meter Possible Causes Detection The power-up self-check is performed automatically each time the key is turned on. Turn the key on and watch the Operator Display Unit (ODU). If lights on the ODU remain on after 15 seconds, or never come on, the self-check has failed.
Fault Isolation Procedures Power-Up Sequence Test Step A Procedure Condition Action 1. Before performing this test, the Electrical Pretest must pass. 2. Clear area around sensor of objects. 3. Key on. 4. Observe the Operator Display Unit. Test complete. If lights fail to turn on Go to Step B. If lights turn on and stay on Go to Step D. Procedure Condition Power-Up Sequence Test Step B If both LED lights turn on for .
Fault Isolation Procedures Power-Up Sequence Test, continued Step C Procedure Condition Action 1. Key off. 2. Disconnect Operator Display Unit from harness J1. 3. Key on. 4. Measure voltage between sensor harness J2 pins 1 and 2. If voltage is between 10 and 14 volts Replace ODU. Go to Step V. If voltage is outside of range Replace sensor. Go to Step V.
Fault Isolation Procedures Power-Up Sequence Test, continued Step D Procedure Condition Action 1. Key off. 2. Disconnect sensor harness J2. 3. Disconnect Operator Display Unit from harness J1. 4. Measure resistance between J1 pin 3 and J2 pin 3. If resistance is between 0 and 0.3 ohms Replace ODU. Go to Step E. If resistance is outside of range Replace sensor. Go to Step V.
Fault Isolation Procedures Power-Up Sequence Test, continued Step E Procedure Condition Action 1. Key off. 2. Disconnect Operator Display Unit from harness J1. 3. Key on. 4. Measure voltage between sensor harness J2 pins 1 and 2. If voltage is between 10 and 14 volts Replace ODU. Go to Step V. If voltage is outside of range Replace Sensor. Go to Step V. VOLT V 4 1 3 2 COM A ODU P1 Step V Procedure Condition Action 1. Key off. 2. Reconnect all connectors. 3. Key on. 4.
Symptom Isolation Procedures Operator Display Unit Audible Indictor (Buzzer) Not Functioning Overview This symptom-driven test is performed when the system fails to detect objects properly. Detection Required Tools • Digital Volt/Ohm Meter Possible Causes The symptom is observed by the driver when: 1) objects closer than ten (10) feet are detected, 2) when the turn signal is activated, and 3) when no audible sound is heard.
Symptom Isolation Procedures Operator Display Unit Audible Indictor (Buzzer) Not Functioning Step A Procedure Condition Action 1. Key off. 2. Active turn signal. 3. Place a target between 3 and 10 feet directly in front of the sensor. Note: If both LEDs are illuminated, go to the appropriate isolation procedure. Step B Procedure If the Operator Display Unit has red LED on and buzzer sounds Test complete. If the Operator Display Unit has red LED on only (no sound) Go to Step B.
Symptom Isolation Procedures Operator Display Unit Audible Indictor (Buzzer) Not Functioning, continued Step C Procedure Condition Action 1. Key off. 2. Disconnect Operator Display Unit from harness J1. 3. Measure resistance between display harness J1 pins 2 and 4. If resistance is between 0 and .5 ohms Go to Step D. If resistance is outside of range Repair wiring harness. Go to Step V.
Symptom Isolation Procedures Operator Display Unit Audible Indictor (Buzzer) Not Functioning, continued Step D Procedure Condition Action 1. Key off. 2. Disconnect Operator Display Unit from harness J1. 3. Key on. 4. Activate turn signal. 5. Measure voltage between display harness J1 pins 2 and 4. If voltage is between 10 and 14 volts Replace display. Go to Step V. If voltage is outside of range Repair wiring harness. Go to Step V.
Symptom Isolation Procedures Side Sensor Not Detecting Targets Overview This symptom driven test is performed when the system fails to detect objects properly. Detection Required Tools • The symptom is observed by the driver when objects at three (3) to ten (10) feet are not detected. The yellow light also continuously illuminates when the sensor has failed. Fallback There is no fallback mode for this symptom. The Sensor will not operate properly.
Symptom Isolation Procedures Side Sensor Not Detecting Targets Step A Procedure Condition Action 1. Clear area around sensor of objects. 2. Key on. 3. Allow Operator Display Unit to go through selftest and shows no targets (yellow LED light should be on). Step B Procedure If both LED lights turn on for .5 seconds – followed by red LED for 5 seconds – followed by a continuous yellow light Go to Step B. If only the yellow LED light turns on for .
Symptom Isolation Procedures Side Sensor Continuous Detection Test Side Sensor Continuously Detecting Targets Overview This symptom driven test is performed when the system continuously detects objects. Detection Required Tools • None Possible Causes The symptom is observed by the driver when sensor continuously detects targets. Fallback This fault code can be caused by any of the following: • Sensor • Operator Display Unit There is no fallback mode for this symptom.
Symptom Isolation Procedures Side Sensor Continuously Detecting Targets Step A Procedure Condition Action 1. Clear area around sensor of objects. 2. Key on. 3. Allow Operator Display Unit to go through self-test and shows no targets (yellow LED light should be on). Step B Procedure If both LED lights turn on for .5 seconds – followed by a red LED for five (5) seconds – followed by a continuous yellow light Go to Step V. If both LED lights turn on for .
Symptom Isolation Procedures Side Sensor Continuous Detection Test Side Sensor Continuously Detecting Targets, continued Step V Procedure Condition Action 1. Key off. 2. Reconnect all connectors. 3. Drive vehicle to determine if problem has been corrected. If complaint has been repaired Test complete. If complaint has not been repaired Return to Step A to find error in testing.
