6. Basic Diagnostics Procedure

D: IGNITION CONTROL SYSTEM
8D1Check ignition system for sparks.
8D2Check power supply circuit for ignition coil.
8D3Check ignition coil.
8D4Check harness between ignitor and ignition
coil connector.
8D5Check input signal for ignitor.
8D6Check harness of ignitor ground circuit.
8D7Check harness between ECM and ignitor
connector.
CAUTION:
After repair or replacement of faulty parts, conduct
CLEAR MEMORY and INSPECTION MODES.

8D1
CHECK IGNITION SYSTEM FOR SPARKS.
1) Remove plug cord cap from each spark plug.
2) Install new spark plug on plug cord cap.
CAUTION:
Do not remove spark plug from engine.
3) Contact spark plug’s thread portion on engine.
4) While opening throttle valve fully, crank engine to check
that spark occurs at each cylinder.
: Does spark occur at each cylinder?
: Check fuel pump system.
: Go to step8D2.
OBD0123A
8D2CHECK POWER SUPPLY CIRCUIT FOR
IGNITION COIL.
1) Turn ignition switch to OFF.
2) Disconnect connector from ignition coil.
3) Turn ignition switch to ON.
4) Measure power supply voltage between ignition coil
connector and engine ground.
: Connector & terminal
(E12) No. 2 (+)—Engine ground ():
Is the voltage more than 10 V?
: Go to step8D3.
: Repair harness between ignition coil and ignition
switch connector.
OBD0124
8D3
CHECK IGNITION COIL.
1) Measure resistance between ignition coil terminals to
check primary coil.
: Terminals
No. 2—No. 1:
Is the resistance between 0.4 and 1.0Ω?
: Go to next.
: Replace ignition coil.
