DTC P0353

Ignition coil No.3 control circuit malfunction

DETECTION CONDITION

• If the PCM detects an abnormal voltage value when ignition coil No.3 is energized under the following monitoring conditions, the PCM determines that the ignition coil No.3 control circuit has a malfunction.
MONITORING CONDITIONS
- Engine speed is less than 3,000 rpm.
- Battery voltage 9-16.5 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.
• The PENDING CODE is available if PCM detects the above malfunction condition.
• The FREEZE FRAME DATA is available.
• The DTC is stored in the PCM memory.

POSSIBLE CAUSE

• Ignition coil malfunction
• Connector or terminal malfunction
• Open circuit between ignition coil No.3 terminal A and PCM terminal 2D
• Open circuit between ignition coil No.3 terminal C and PCM terminal 2AU
• Short to power between ignition coil No.3 terminal C and PCM terminal 2AU
• Open circuit between ignition coil No.3 terminal B and body ground
• PCM 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 the FREEZE FRAME DATA on the repair order, then go to the next step.
2
VERIFY RELATED REPAIR INFORMATION AVAILABILITY
• Verify related service repair information availability.
• Is any related repair information available?
Yes
Perform repair or diagnosis according to the available repair information.
• If the vehicle is not repaired, go to the next step.
No
Go to the next step.
3
INSPECT IGNITION COIL NO.3 FOR POOR CONNECTION
• Turn the ignition switch off.
• Disconnect the ignition coil No.3 connector.
• Inspect for poor connection (such as damaged, pulled-out pins, and corrosion).
• Is there any malfunction?
Yes
Repair or replace the terminal, then go to Step 10.
No
Go to the next step.
4
INSPECT IGNITION COIL NO.3 ELECTRICAL MALFUNCTION
• Inspect ignition coil No.3.
• Is ignition coil No.3 normal?
Yes
Go to the next step.
No
Replace the ignition coil No.3, then go to Step 10.
5
INSPECT CONTROL CIRCUIT FOR SHORT TO POWER
• Turn the ignition switch to the ON position (Engine off).
• Measure the voltage between following terminal and body ground:
- Ignition coil No.3 terminal C (wiring harness-side)
• Is the voltage B+?
Yes
Repair or replace the wiring harness, then go to Step 10.
No
Go to the next step.
6
INSPECT POWER CIRCUIT FOR OPEN CIRCUIT
• Turn the ignition switch off.
• Inspect for continuity between the following terminals:
- Ignition coil No.3 terminal A (wiring harness-side) and PCM terminal 2D (wiring harness-side)
• Is there continuity?
Yes
Go to the next step.
No
Repair or replace the wiring harness, then go to Step 10.
7
INSPECT PCM FOR POOR CONNECTION
• Turn the ignition switch off.
• Disconnect the PCM connector.
• Inspect for poor connection (such as damaged, pulled-out pins, and corrosion).
• Is there any malfunction?
Yes
Repair the terminal, then go to Step 10.
No
Go to the next step.
8
INSPECT CONTROL CIRCUIT MALFUNCTION FOR OPEN CIRCUIT
• Inspect for continuity between the following terminals:
- Between ignition coil No.3 terminal C (wiring harness-side) and PCM terminal 2AU wiring harness-side)
• Is there continuity?
Yes
Go to the next step.
No
Repair or replace the wiring harness, then go to Step 10.
9
INSPECT GROUND CIRCUIT MALFUNCTION FOR OPEN CIRCUIT
• Inspect for continuity between the following terminals:
- Between ignition coil No.3 terminal B (wiring harness-side) and body ground
• Is there continuity?
Yes
Go to the next step.
No
Repair or replace the wiring harness, then go to Step 10.
10
VERIFY TROUBLESHOOTING OF DTC P0353 COMPLETED
• Make sure to reconnect all disconnected connectors.
• Clear the DTC using the WDS or equivalent.
• Perform the KOER self-test.
• Is the same DTC present?
Yes
Replace the PCM, then go to the next step.
No
Go to the next step.
11
VERIFY AFTER REPAIR PROCEDURE
• Perform the "AFTER REPAIR PROCEDURE".
• Are any DTCs present?
Yes
Go to applicable DTC troubleshooting.
No
Troubleshooting completed.
