Diagnostic procedure

STEP

INSPECTION

ACTION
1
VERIFY FREEZE FRAME DATA HAS BEEN RECORDED
•  Has FREEZE FRAME DATA been recorded?
Yes
Go to the next step.
No
Record FREEZE FRAME DATA on the repair order, then go to the next step.
2
VERIFY RELATED SERVICE INFORMATION AVAILABILITY
•  Verify related Service Information availability.
•  Is any related Service Information available?
Yes
Perform repair or diagnosis according to the available Service Information.
•  If the vehicle is not repaired, go to the next step.
No
Go to the next step.
3
INSPECT IGNITION COIL CONNECTOR FOR POOR CONNECTION
•  Turn the ignition switch off.
•  Disconnect the ignition coil connector.
•  Inspect for poor connection (such as damaged/ pulled-out pins, corrosion).
•  Are there any malfunction?
Yes
Repair or replace suspected part, then go to Step 11.
No
Go to the next step.
4
INSPECT IGNITION COIL POWER SUPPLY CIRCUIT FOR OPEN CIRCUIT
•  Ignition coil connector is disconnected.
•  Turn the ignition switch to the ON position (Engine off).
•  Measure the voltage between ignition coil terminal A (wiring harness-side) and body ground.
•  Is the voltage B+?
Yes
Go to the next step.
No
Repair or replace suspected part, then go to Step 11.
5
INSPECT IGNITION COIL SIGNAL CIRCUIT FOR SHORT TO POWER SUPPLY OR ELSEWHERE
•  Ignition coil connector is disconnected.
•  Turn the ignition switch to the ON position (Engine off).
•  Measure the voltage between ignition coil terminal C (wiring harness-side) and body ground.
•  Is the voltage B+?
Yes
Go to the next step.
No
Go to Step 7.
6
INSPECT IGNITION COIL SIGNAL CIRCUIT FOR SHORT TO POWER SUPPLY
•  Ignition coil connector is disconnected.
•  Disconnect PCM connector.
•  Turn the ignition switch to the ON position (Engine off).
•  Measure the voltage between ignition coil terminal C (wiring harness-side) and body ground.
•  Is the voltage B+?
Yes
Repair or replace suspected part, then go to Step 11.
No
Go to Step 10.
7
INSPECT IGNITION COIL SIGNAL CIRCUIT FOR SHORT TO GROUND
•  Ignition coil connector is disconnected.
•  Turn the ignition switch off.
•  Inspect continuity between ignition coil terminal C (wiring harness-side) and body ground.
•  Is there continuity?
Yes
Repair or replace suspected part, then go to Step 11.
No
Go to the next step.
8
INSPECT PCM CONNECTOR FOR POOR CONNECTION
•  Disconnect PCM connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
•  Is there any malfunction?
Yes
Repair or replace suspected part, then go to Step 11.
No
Go to the next step.
9
INSPECT IGNITION COIL SIGNAL CIRCUIT FOR OPEN CIRCUIT
•  Ignition coil and PCM connectors are disconnected.
•  Inspect continuity between the following circuits:
―  Ignition coil No.1 terminal C (wiring harness-side) and PCM terminal 2BB (wiring harness-side)
―  Ignition coil No.2 terminal C (wiring harness-side) and PCM terminal 2AT (wiring harness-side)
―  Ignition coil No.3 terminal C (wiring harness-side) and PCM terminal 2B (wiring harness-side)
―  Ignition coil No.4 terminal C (wiring harness-side) and PCM terminal 2AX (wiring harness-side)
―  Ignition coil No.5 terminal C (wiring harness-side) and PCM terminal 2C (wiring harness-side)
―  Ignition coil No.6 terminal C (wiring harness-side) and PCM terminal 2D (wiring harness-side)
•  Are there continuity?
Yes
Replace the PCM. (PCM internal circuit malfunction)
(See PCM REMOVAL/INSTALLATION [MZI-3.7].)
Go to Step 11.
No
Repair or replace suspected part, then go to Step 11.
10
INSPECT IGNITION COIL
•  Inspect ignition coil.
•  Are there ignition coil normal?
Yes
Go to the next step.
No
Replace the ignition coil, then go to the next step.
