1. Phase sensor

(a) Turn on ignition switch but do not start engine, and place digital universal meter at DC voltage gear,

then connect 2 terminals respectively to 1

pin via vehicle oscilloscope.

2. Speed Sensor

(a) Remove speed sensor joint.

(b) Place digital universal meter at ohm gear, and connect 2 terminals respectively to 2

Inspection

1. Spark plug

(a) Clean spark plug.

Air pressure:  below 588kPa.

Time:  20 s or less

(b) Check the damage condition of spark plug and insulator. If

there is something abnormal, please replace with new spark

plug.

Recommended spark plug specification:

Made in Xianghuoju Company:  K6RTC

(c) Adjust electrode gap.

Electrode gap:  0.8mm

3. Inspection of ignition coil (including igniter) and spark test

(a) Check DTC.

Note:  if there is display with DTC, perform trouble shooting according to DTC procedure.

(b) Check there is spark.

(1) Remove ignition coil (including igniter).

(2) Remove spark plug with 16mm spark plug sleeve.

(3) Install spark plug to each ignition coil (including igniter), and connect ignition coil joint.

(4) Uncouple joints of 4 injection nozzles.

(5) Earth spark plug.

(6) Check spark with engine running.

Notes:

Be sure to earth spark plug during checking.

 When there is falling or collision with ignition coil,please replace with a new one

Running engine time for each time should not be more than 2 seconds.

If there is no spark, please perform test as the following steps.

(c) Install spark plug with 16mm spark plug sleeve.

Torque:  

(d) Install ignition coil and igniter.

Torque:  

4. Test procedure in the state of not spark

Perform step 3

Spark test

Replace with a new spark plug

Replace bad spark plug with a good one, and perform spark test again.

Spark plug is not good

Replace all spark plugs with new ones, and perform spark plug again.

Replace with a new ignition coil (including igniter)

Replace bad ignition coil (including igniter) with a new one.

Inspection

1. Starter installation components

Note: this test must be finished within 3 to 5 seconds to

avoid burning out coil.

(a) Remove nut at C terminal to uncouple wire of field coil.

(b) As shown in the diagram, connect battery wire to electro-

magnetic switch, and check drive pinion is pushed outside,

(pull-in coil and hold-in coil).

(c) As shown in the diagram, uncouple negative wire from ter-

minal C after the above connections, and check drive pin-

ion is still at the state of being pushed outside.(Hold-in coil)

(d) Push drive pinion toward armature side, and measure the

clearance between drive pinion end and stop ring.

Standard clearance:  1.0~5.0mm

(e) Uncouple negative wire from electromagnetic switch

housing, and check drive pinion returns back to original

position toward inside.

(j) As shown in the diagram, connect battery with ampere

meter.

(k) Read current value displayed on ampere meter.
