The Test Status box at the bottom of the menu will also display the status of this test. This rate equals a wheel speed of approximately 4 mph 7 kph. Strain relief is defined as a small amount of slack in the cable at the area of connection. Cables without adequate strain relief can potentially stress a cable connection enough that moisture could intrude. Do not coil the cable and pinch into a bowtie or dog-bone shape. Brake hose clips with a provision for the sensor extension cable are recommended as opposed to tie wraps. Contact your suspension manufacturer for further information.
Use the industry-standard connector cable or a blunt-cut power cable. Place a thin barrier made of plastic, mylar or similar material between the bracket and mounting surface to inhibit the possibility of corrosion. If the axles are not correctly grounded to the chassis, a ground strap electrically connecting the axle to the chassis may be added to ensure adequate protection from unwanted electrical noise. . Pipes with pre-applied thread sealant may also be used. Cable clips are preferred over zip ties. It is important to note that cables should be secured only to the extent that the cable is held sufficiently in place.
Repeat Step 1 and Step 2. First fastener must be a minimum 6-inches 152 mm and a maximum of 12-inches 305 mm from connector. Check the Faults field on the Main Screen. Figure 14 Figure 15 4003562b Figure 14 2. The internal field is not applicable to this test. It is important to remember that cables should be fastened in a manner where the cable is secured enough where the cable will not move or chafe against what it is mounted to.
Verify there is sensor output. Use of a vise may cause overclamping. The assembly may be mounted on the air tank or on the cross member of the vehicle. You must always disconnect the battery ground cable before working on the electrical system. The end of line test is complete.
After performing the necessary repairs, repeat the end of line test to verify correct sensor installation. Overtightening can damage the cable. The barrier is necessary to inhibit corrosion, which can occur from contact between dissimilar metals. Regardless of whether zip ties or cable clips are used, cables should be secured at intervals not greater than 18-inches 457 mm to avoid cable vibration.

The suspension manufacturer can provide this information. Fasten the excess cable to an area that is free of sharp edges and moving components.
Click on the Activate button and listen for the valve to click, indicating a good installation. Perform the necessary repairs and repeat the test. If this is not the case, the electrical contact at the common chassis ground point is not sufficient or not present. Repeat the sensor installation check. Install the diagnostic cable bracket so that the diagnostic plug is accessible. Install the wheel hub carefully so that the tooth wheel pushes against the sensor as the wheel bearings are adjusted.
Have the following installation material available. Leave enough slack in the cable to compensate for flexing of the trailer and sub-frame. Fault Code Check Perform necessary repairs. Do not tie wrap the molded sensor plug. Secure excess cable in the sub-frame of the vehicle or along the air hoses as appropriate. A good rule of thumb is to have the bend of the cable, also known as bend radius, be greater than or equal to ten times the diameter of the cable. If you are using a Pro-Link, refer to the operating manual for test instructions.
Identify the type of cable to be installed. Sensor Gap Adjustment Perform any necessary repairs. Failure to provide adequate strain relief on the cables can result in future maintenance that is not covered under warranty. This rate equals a wheel speed of approximately 4 mph 7 kph. Use constant power activation to perform the following fault code check.
Without the strain relief, normal trailer jounce and vibration will cause the terminals to spread and loosen. Check the screen for the correct voltage 9. Cable strain relief is a universal practice. Click on Close to exit. Serious personal injury and damage to components can result. Apply air to the emergency supply line to fill the air tanks and release the spring brakes so that the wheels can be rotated. Plug any unused delivery ports.
