DTC P0354:00

Ignition coil No.4 circuit problem
DETECTION CONDITION
•  The PCM monitors ignition signal to the ignition coil No.4 when the following condition. If the ignition signal is not changed, the PCM determines that the ignition coil No.4 circuit has a malfunction.
MONITORING CONDITIONS
―  Battery voltage: 11—15 V
Diagnostic support note
•  This is a continuous monitor (CCM).
•  The MIL illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM.
•  PENDING CODE is available if the PCM detects the above malfunction condition during the first drive cycle.
•  FREEZE FRAME DATA (Mode 2)/Snapshot data is available.
•  The DTC is stored in the PCM memory.
POSSIBLE CAUSE
•  Ignition coil No.4 connector or terminals malfunction
•  Ignition coil No.4 malfunction
•  Open circuit in wiring harness between Ignition coil No.4 terminal B and body ground
•  Short to ground in wiring harness between the following terminals:
―  Ignition coil No.4 terminal A—PCM terminal 2D
―  Ignition coil No.4 terminal C—PCM terminal 2AV
•  PCM connector or terminals malfunction
•  Short to power supply in wiring harness between ignition coil No.4 terminal C and PCM terminal 2AV
•  Open circuit in wiring harness between the following terminals:
―  Ignition coil No.4 terminal A—PCM terminal 2D
―  Ignition coil No.4 terminal C—PCM terminal 2AV
•  PCM malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION
1
VERIFY FREEZE FRAME DATA (MODE 2)/SNAPSHOT DATA HAS BEEN RECORDED
•  Has the FREEZE FRAME DATA (Mode 2)/snapshot data been recorded?
Yes
Go to the next step.
No
Record the FREEZE FRAME DATA (Mode 2)/snapshot 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 NO.4 CONNECTOR AND TERMINALS
•  Turn the ignition switch off.
•  Disconnect the ignition coil No.4 connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
•  Is there any malfunction?
Yes
Repair or replace the connector or terminals, then go to Step 10.
No
Go to the next step.
4
INSPECT IGNITION COIL NO.4
•  Inspect the ignition coil No.4.
•  Is there any malfunction?
Yes
Replace the ignition coil No.4, then go to Step 10.
(See IGNITION COIL REMOVAL/INSTALLATION [ZJ, ZY].)
No
Go to the next step.
5
INSPECT IGNITION COIL NO.4 GROUND CIRCUIT FOR OPEN CIRCUIT
•  Ignition coil No.4 connector is disconnected.
•  Inspect for continuity between ignition coil No.4 terminal B (wiring harness-side) and body ground.
•  Is there continuity?
Yes
Go to the next step.
No
Repair or replace the wiring harness for a possible open circuit, then go to Step 10.
6
INSPECT IGNITION COIL NO.4 CIRCUIT FOR SHORT TO GROUND
•  Ignition coil No.4 connector is disconnected.
•  Inspect for continuity between the following terminals (wiring harness-side) and body ground:
―  Ignition coil No.4 terminal A
―  Ignition coil No.4 terminal C
•  Is there continuity?
Yes
If the short to ground circuit could be detected:
•  Repair or replace the wiring harness for a possible short to ground.
If the short to ground circuit could not be detected:
•  Replace the PCM (short to ground in PCM internal circuit).
Go to Step 10.
No
Go to the next step.
7
INSPECT PCM CONNECTOR AND TERMINALS
•  Disconnect the PCM connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
•  Is there any malfunction?
Yes
Repair or replace the connector or terminals, then go to Step 10.
No
Go to the next step.
8
INSPECT IGNITION COIL NO.4 CONTROL CIRCUIT FOR SHORT TO POWER SUPPLY
•  Ignition coil No.4 and PCM connectors are disconnected.
•  Turn the ignition switch to the ON position (engine off).
•  Measure the voltage between ignition coil No.4 terminal C (wiring harness-side) and body ground.
•  Is there any voltage?
Yes
Repair or replace the wiring harness for a possible short to power supply, then go to Step 10.
No
Go to the next step.
9
INSPECT IGNITION COIL NO.4 CIRCUIT FOR OPEN CIRCUIT
•  Ignition coil No.4 and PCM connectors are disconnected.
•  Turn the ignition switch off.
•  Inspect for continuity between the following terminals (wiring harness-side):
―  Ignition coil No.4 terminal A—PCM terminal 2D
―  Ignition coil No.4 terminal C—PCM terminal 2AV
•  Is there continuity?
Yes
Go to the next step.
No
Repair or replace the wiring harness for a possible open circuit, then go to the next step.
10
VERIFY DTC TROUBLESHOOTING COMPLETED
•  Make sure to reconnect all disconnected connectors.
•  Clear the DTC from the PCM memory using the M-MDS.
•  Perform the KOER self test.
•  Is the PENDING CODE for this DTC present?
Yes
Replace the PCM, then go to the next step.
(See PCM REMOVAL/INSTALLATION [ZJ, ZY].)
No
Go to the next step.
11
VERIFY AFTER REPAIR PROCEDURE
•  Perform the “AFTER REPAIR PROCEDURE”.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
(See DTC TABLE [ZJ, ZY].)
No
DTC troubleshooting completed.
