Electromagnetic Interference

ABS components are sensitive to Electromagnetic Interference (EMI).

Perform the following checks if an intermittent malfunction is suspected:
^ Check for proper installation of the wiring harnesses resulting from add-on options.
^ Visually inspect the wheel speed sensor and the toothed ring for the following conditions.
^ Looseness
^ Damage (Replace any damaged components)
^ Foreign material accumulation (Remove any foreign material)
^ Proper mounting (Properly attach all of the components).
^ Check for proper routing of the front wheel speed sensor wiring near the spark plug wires.
^ Use the DMM J 39200 in order to measure the resistance of the spark plug wires. If the displays J 39200 Infinite or greater than 30,000 ohms for any wire, replace the spark plug wires.
^ While test driving the vehicle, monitor the Scan Tool wheel speeds. If any wheel speed drops or becomes erratic, refer to the appropriate wheel speed DTC.
