DTC P0353

Ignition coil No.3 control circuit problem

DETECTION CONDITION

• If the PCM detects abnormal current value when the ignition coil No.3 is energized under the following conditions, the PCM determines that the ignition coil No.3 control circuit has a malfunction.
MONITORING CONDITION
- Engine speed is less than 3,000 rpm
- Battery voltage is 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
• Short to GND in wiring harness between ignition coil No.3 terminal A and PCM terminal 2A
• Short to power supply in wiring harness between ignition coil No.3 terminal C and PCM terminal 2Q
• Open circuit in wiring harness between ignition coil No.3 terminal C and PCM terminal 2Q
• Short to GND in wiring harness between ignition coil No.3 terminal C and PCM terminal 2Q
• Open circuit in wiring harness between ignition coil No.3 terminal B and GND
• 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 CONNECTOR 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 terminal, then go to Step 9.
No
Go to next step.
4
INSPECT IGNITION COIL NO.3
• Inspect the ignition coil No.3.
• Is the ignition coil No.3 normal?
Yes
Go to next step.
No
Replace ignition coil No.3, then go to Step 9.
5
INSPECT IGNITION COIL NO.3 CIRCUIT FOR SHORT TO POWER SUPPLY
• Turn the ignition switch to the ON position (Engine off).
• Measure voltage between following terminal and body ground:
- Ignition coil No.3 terminal C (wiring harness-side)
• Is voltage B+?
Yes
Repair or replace wiring harness, then go to Step 9.
No
Go to next step.
6
INSPECT IGNITION COIL NO.3 CIRCUIT FOR SHORT TO GND
• Turn the ignition switch off.
• Inspect continuity between following terminal and body ground:
- Ignition coil No.3 terminal A (wiring harness-side)
- Ignition coil No.3 terminal C (wiring harness-side)
• Is there continuity?
Yes
Repair or replace wiring harness, then go to Step 9.
No
Go to next step.
7
INSPECT PCM CONNECTOR 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 terminal, then go to Step 9.
No
Go to next step.
8
INSPECT IGNITION COIL NO.3 CIRCUIT FOR OPEN CIRCUIT
• Inspect continuity following terminals:
- Between ignition coil No.3 terminal C (wiring harness-side) and PCM terminal 2Q (wiring harness-side)
- Between ignition coil No.3 terminal B (wiring harness-side) and GND
• Is there continuity?
Yes
Go to next step.
No
Repair or replace wiring harness, then go to next step.
9
VERIFY TROUBLESHOOTING OF DTC P0353 COMPLETED
• Make sure to reconnect all disconnected connectors.
• Clear the DTC from the PCM memory using the WDS or equivalent.
• Start the engine.
• Is the same DTC present?
Yes
Replace the PCM, then go to the next step.
No
Go to the next step.
10
VERIFY AFTER REPAIR PROCEDURE
• Perform the "AFTER REPAIR PROCEDURE".
• Are any DTCs present?
Yes
Go to the applicable DTC inspection.
No
DTC troubleshooting completed.
