Intermittent DTC Troubleshooting
If malfunction is intermittent, perform the followings:
Check if connectors are loose.
Check if wire harnesses are worn, pierced, pinched or partially broken.
Wiggle related wire harnesses and connectors and observe if signal is interrupted in related circuit.
If possible, try to duplicate the conditions under which the DTC was set.
Look for the data that has changed or the DTC to be reset during the wiggle test.
Look for broken, bent, protruded or corroded terminals.
Inspect the mounting areas of wheel speed sensor for damage, foreign matter, etc. that will cause incorrect
signals.
Check and clean all wire harness connectors and grounding parts related to the current DTC.
Remove the ABS control module assembly from the malfunctioning vehicle and install it to a new vehicle
and perform a test. If DTC cannot be cleared, the ABS control module is malfunctioning. If DTC can be
cleared, reinstall the ABS control module assembly to original vehicle.
If multiple trouble codes were set, refer to the circuit diagrams to look for any common ground circuit or
power supply circuit applied to the DTC.
Refer to Technical Bulletin that is applied to the malfunction.
Ground Inspection
Groundings are very important to the proper operation of circuits. Groundings are often exposed to moisture,
dirt and other corrosive environments. Corrosion (rust) may increase load resistance. This situation may
change the way in which a circuit works.
Circuits are very sensitive to proper grounding. A loose or corroded ground can affect the control circuit.
The operations to check the ground points are as follows:
1. Remove the ground bolt or nut.
2. Check all contact surfaces for tarnish, dirt, rust, etc.
3. Clean as necessary to ensure that contacting is in a good condition.
4. Reinstall the ground bolt or nut securely.
5. Check if add-on accessories interfere with the ground circuit.
6. If several wire harnesses are crimped into one ground terminal, check if they are installed correctly. Make
sure all wire harnesses are clean, securely fastened and providing a good ground path.
