A tank with a reinforced port must be used. These adjustments may be necessary for the module to accurately calculate the vehicle velocity and odometer mileage. Remote modulator harnesses are available in many lengths to satisfy most installation requirements. Whenever the module is towed using a pre-1997tractor, the electronic odometer does not function, and the mileage can be considered out-of-calibration. Measure resistance between retarder disable output of and sensor.
Recheck for leakage around the relay exhaust port. Use only genuine Bendix ® replacement parts, components and kits. Park the vehicle on a level surface, apply the parking brakes, and always block the wheels. . For more information on these diagnostic tools, contact Bendix or refer to your local authorized Bendix dealer or distributor.
Blink code diagnostics can also be used to reset active fault codes. Blink Location Code Power Supply 2nd. See Figures 7 and 8. Each sensor is installed with a Bendix Sensor Clamping Sleeve. When braking on even surfaces, a dolly axle control system will perform similar to side control or axle control system.
In this case, go to Section F. Diagnostic Blink Trouble Code Repair Information Code Description Battery Voltage Measure battery voltage under load. Use only the proper tools and observe all precautions pertaining to use of those tools. Vehicle stability is assisted by not allowing the high coefficient wheel where traction is still being maintained to sustain wheel lock. Fully charge air brake system and verify proper brake adjustment.
Check all wiring and connectors to ensure they are secure and free from visible damage e. Probe the connector carefully so that the terminals are not damaged. Remove as much contamination as possible prior to disconnecting electrical connections and air hoses. If the vehicle begins moving before the new configuration has been accepted, the reconfiguration will not take place at this time. Too Low Check for damaged wiring. Verify that the connector pins are properly greased with a non-conductiveelectrical grease compound. The other side of the lamp is grounded.
With brake pressure applied, a properly installed modulator will cause five rapid audible chuffs of air pressure. In the case of an unbalanced braking surface, e. Turn off the power to the module. The operating voltage range is 8. The trouble codes will be logged once again after driving the vehicle. If this label is not readable for any reason, the Bendix part number is etched into the module casting above the control port See Figure 1. The front sensor is accessible on the inboard side of the steering knuckle.
There is also a 24- volt version. The chuff sequence is then repeated. Check connectors for proper insertion and locking. A tank with a reinforced port must be used. Access active trouble code s using either the Blink Code procedure, with ServiceRanger or the Hand-held Tester procedure. Apply a moderate amount of dielectric non-conductivegrease to both the sensor connector and harness connector. Check for kinks and blockages etc.
The following troubleshooting flow charts will help the technician isolate the cause of the fault and confirm whether the fault resides in the component, wiring or connectors. Bendix Part Number Bendix Part Number Serial Number Date Code. If additional scratch pad space is needed, this storage space can be expanded to 1K 1,008 bytes total of data. Probe the connector carefully so that the terminals are not damaged. Diagnostics, testing, configuration, data transfer and other functions can be performed using this link.
Install the sensor bushing with the flange stops toward The rear axle speed sensor located inside the brake drum the inboard side of the vehicle. Stop the engine and remove ignition key when working under or around the vehicle. The other side of the lamp is grounded. Following activation, there will be a 5-seconddelay followed by a blink code display of the odometer information x1000. Activation requires a magnet with 30 gauss minimum. The program provides the reading of the sensor.
Engage the connectors, and push together until the lock tab snaps into place. Technicians can use these latched codes to assist them in troubleshooting intermittent errors. Any components found to be damaged should not be installed on the vehicle and must be replaced. Apply power and monitor the power-up sequence to verify proper system operation. Trip Counter The module provides a counter to record the trip mileage. If the modulator is wired incorrectly, the modulator will only produce one chuff, or no chuff at all.
