IGNITION SIGNAL

IGNITION SIGNAL

PFP:22448

Component Description

UBS00DCZ

IGNITION COIL & POWER TRANSISTOR

The ignition signal from the ECM is sent to the power transistor. The
power transistor switches the ignition coil primary circuit ON and
OFF. As the primary circuit is turned ON and OFF, the proper high
voltage is induced in the coil secondary circuit.
The distributor is not repairable and must be replaced as an assem-
bly except distributor cap and rotor head.

NOTE:
The rotor screw which secures the distributor rotor head to the dis-
tributor shaft must be tightened properly.

IGNITION SIGNAL

Specification data are reference values and are measured between each terminal and ground.

CAUTION:

Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.

: Average voltage for pulse signal (Actual pulse signal can be confirmed by oscilloscope.)

Diagnostic Procedure

1. 

INSPECTION START

Turn ignition switch OFF, and restart engine.
Is engine running?

Yes or No

Yes (With CONSULT-II)>>GO TO 2.
Yes (Without CONSULT-II)>>GO TO 3.
No

>> GO TO 4.
