Step 2
Check visually and physically.
This step is an important method to initially identify the fault
location:
(a)
Check wiring harness for damage, wear and tear.
(b)
Check whether the wiring harness routed properly. Do not
place wiring harness near a device with high voltage or high
current running through:
•
Such as start motor, generator and other motor
components. When these components are working, they
will introduce great electromagnetic interference, thus
affecting the proper signal transmission, resulting in
system not working properly.
•
Ignition coil, ignition wires and other components.
(c)
Check whether there is a vacuum hose cracking, damage or
distortion. Confirm the hoses correct connection and routing.
(d)
Check whether there is air intake system leak, for example,
throttle body installation surface, idle speed control valve,
intake manifold sealing surface and so on.
(e)
Check the engine control module (ECM) ground and the body
ground whether there is oxidation, loose, incorrect position.
The control system ground can not be changed at will, as this
will affect the proper operation of the control system .
(f)
Check whether the battery positive and negative cable
connections are reliable, whether there is loose, oxidation,
corrosion and so on.

Step 3
Check wiring harnesses and connectors.
(a)
Many intermittent faults are caused by vibration, distortion,
uneven roads, improper operation of components or
connectors dislocation.
(b)
If the circuit resistance is too high, it may result in components
not working properly. Use a scan tool to drive the actuators,
if not working, check whether the resistance in the circuit is
too high or other faults.
