The ABS components are sensitive to electromagnetic interference
(EMI). Perform the following checks if an intermittent malfunction is suspected:
| • | Check for proper installation of wiring harnesses resulting from
add-on options. |
| • | Visually inspect the wheel speed sensor and the toothed ring for
the following conditions. Remove any foreign material and replace any damaged
components. Properly attach all components. |
| - | Foreign material accumulation. |
| • | Check for proper routing of the wheel speed sensor wiring near
spark plug wires. |
| • | Use the special tool J 39200
DMM to measure the resistance of the spark plug wires. |
| • | Monitor the scan tool wheel speeds while test driving the vehicle.
Refer to the appropriate wheel speed DTC if any wheel speed drops or displays
an erratic speed. |
