DETECTION CONDITION | • Each ignition primary circuit is continuously monitored. The test fails when the PCM does not receive a valid ignition diagnostic monitor pulse signal from the ignition module (integrated in the PCM).
POSSIBLE CAUSE | • Connector or terminal malfunction • Open circuit between ignition coil terminal A and main relay No.2 terminal D • Short to power supply between ignition coil No.1 terminal C and PCM terminal 2BB • Short to power supply between ignition coil No.2 terminal C and PCM terminal 2AT • Short to power supply between ignition coil No.3 terminal C and PCM terminal 2B • Short to power supply between ignition coil No.4 terminal C and PCM terminal 2AX • Short to power supply between ignition coil No.5 terminal C and PCM terminal 2C • Short to power supply between ignition coil No.6 terminal C and PCM terminal 2D • Short to ground circuit between ignition coil No.1 terminal C and PCM terminal 2BB • Short to ground circuit between ignition coil No.2 terminal C and PCM terminal 2AT • Short to ground circuit between ignition coil No.3 terminal C and PCM terminal 2B • Short to ground circuit between ignition coil No.4 terminal C and PCM terminal 2AX • Short to ground circuit between ignition coil No.5 terminal C and PCM terminal 2C • Short to ground circuit between ignition coil No.6 terminal C and PCM terminal 2D • Open circuit between ignition coil No.1 terminal C and PCM terminal 2BB • Open circuit between ignition coil No.2 terminal C and PCM terminal 2AT • Open circuit between ignition coil No.3 terminal C and PCM terminal 2B • Open circuit between ignition coil No.4 terminal C and PCM terminal 2AX • Open circuit between ignition coil No.5 terminal C and PCM terminal 2C • Open circuit between ignition coil No.6 terminal C and PCM terminal 2D • PCM malfunction • Ignition coil malfunction

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. (See IGNITION COIL INSPECTION [MZI-3.7].) • Are there ignition coil normal? | Yes | Go to the next step.
No | Replace the ignition coil, then go to the next step.
11 | VERIFY TROUBLESHOOTING OF DTC P0351:00, P0352:00, P0353:00, P0354:00, P0355:00 and P0356:00 COMPLETED • Verify that all disconnected connectors reconnected. • Clear the DTC from the PCM memory using the M-MDS. • Perform the KOEO or KOER self-test. (See KOEO/KOER SELF TEST [MZI-3.7].) • Is the PENDING CODE for the DTC present? | Yes | Repeat the inspection from Step 1. • If the malfunction recurs, replace the PCM. (See PCM REMOVAL/INSTALLATION [MZI-3.7].) Go to the next step.
No | Go to the next step.
12 | VERIFY AFTER REPAIR PROCEDURE • Perform the “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE [MZI-3.7].) • Are any DTCs present? | Yes | Go to the applicable DTC inspection. (See DTC TABLE [MZI-3.7].)
No | Troubleshooting completed.
