On-Vehicle Inspection - Toyota 4Y 2006 Manual

ON-VEHICLE INSPECTION
Caution:
Do not confuse the positive and negative terminals of the battery.
Do not remove the battery cable while the engine is running.
Do not perform any operations that generate destructive pulse.
Make sure the firm connection without any wrong wiring.
When pulling out the resistive cord, do not pull the cord section.
Secondary
resistance
Primary coil resistance
1. lnspection of the resistive cord
(1) Remove the distributor cap.
(2) Using the circuit tester, measure the resistance of the
resistive cord.
Limit: less than 25 kwone cord
2.
lnspection of the ignition coil
(1) Measurement of the primary coil resistance
Standard: 1.2 to 1.5 R
(2) Measurement of the secondary coil resistance
Standard: 7.7 to 10.4 kR
3. lnspection of the igniter
Remove the distributor cap, the rotor, and the dust cover.
(1) lnspection of the input voltage
(a) Turn the ignition key switch on.
(b) Measure the voltage between the positive terminal of
the ignition coil and the earth.
Standard: approx. 12 V
(2) lnspection of the transistor OFF
(a) Turn the ignition key switch on.
(b) Disconnect the inspection connector.
(c) Measure the voltage between the black wire side of
the inspection connector and the earth.
Standard: approx. 12 V
