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 the 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 reset during the wiggle test.
 Look for broken, bent, protruded or corroded terminals.
 Inspect the mounting areas of instrument cluster, wire harness or wire harness connector and so on for
damage, foreign matter, etc. that will cause incorrect signals.
Ground Inspection
Groundings are very important to entire circuit system, which are normal or not can seriously affect the entire
circuit system. Ground points are often exposed to moisture, dirt and other corrosive environments. Corrosion
(rust) and oxidation can increase load resistance. This situation will seriously affect the normal operation of
the 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 and 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 eyelet terminal, check if they are installed correctly.
Make sure all wire harnesses are clean, securely fastened and providing a good ground path.
