DTC P0352

Ignition coil No.2 and No.3 control circuit problem

DETECTION CONDITION

• If the PCM detects an abnormal current value when ignition coil No.2 and No.3 are energized under the following conditions, the PCM determines that the ignition coil No.2 and No.3 control circuit has a malfunction.
Diagnostic support note
• The MIL illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle if 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 terminal B and ignition switch
• Open circuit between ignition coil terminal A and PCM terminal 53
• Short to power or ground between ignition coil terminal A and PCM terminal 53
• PCM malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION

1
PERFORM DTC CONFIRMATION PROCEDURE
• Perform the "DTC CONFIRMATION PROCEDURE".
• Is same DTC present?
Yes
Go to next step.
No
Intermittent concern exists. Go to INTERMITTENT CONCERN TROUBLESHOOTING procedure.
2
INSPECT POOR CONNECTION OF IGNITION COIL CONNECTOR
• Turn the ignition switch off.
• Disconnect the ignition coil connector.
• Inspect for poor connection (such as damaged, pulled-out pins, and corrosion).
• Is there any malfunction?
Yes
Repair or replace terminals, then go to Step 9.
No
Go to next step.
3
INSPECT IGNITION COIL NO.2 AND NO.3 ELECTRICAL MALFUNCTION
• Inspect ignition coil No.2 and No.3.
• Is ignition coil No.2 normal?
Yes
Go to next step.
No
Replace ignition coil No.2 and No.3, then go to Step 9.
4
INSPECT CONTROL CIRCUIT FOR SHORT TO POWER
• Turn the ignition switch to the ON position (Engine off).
• Measure voltage between the following terminal and body ground:
- Ignition coil terminal A (wiring harness-side)
• Is voltage B+?
Yes
Repair or replace wiring harness, then go to Step 9.
No
Go to next step.
5
INSPECT CONTROL CIRCUIT FOR SHORT TO GROUND
• Turn the ignition switch off.
• Inspect continuity between the following terminal and body ground:
- Ignition coil terminal A (wiring harness-side)
• Is there continuity?
Yes
Repair or replace the wiring harness, then go to Step 9.
No
Go to next step.
6
INSPECT POOR CONNECTION OF PCM CONNECTOR
• 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 terminals, then go to Step 9.
No
Go to next step.
7
INSPECT CONTROL CIRCUIT MALFUNCTION FOR OPEN CIRCUIT
• Inspect continuity following terminals:
- Between ignition coil terminal A (wiring harness-side) and PCM terminal 53 (wiring harness-side)
• Is there continuity?
Yes
Go to next step.
No
Repair or replace the wiring harness, then go to Step 9.
8
INSPECT POWER CIRCUIT MALFUNCTION FOR OPEN CIRCUIT
• Inspect continuity following terminals:
- Between ignition coil terminal B (wiring harness-side) and ignition switch
• Is there any continuity?
Yes
Go to next step.
No
Repair or replace wiring harness, then go to Step 9.
9
VERIFY TROUBLESHOOTING OF DTC P0352 COMPLETED
• Make sure to reconnect all disconnected connectors.
• Clear the DTC using WDS or equivalent.
• Perform the KOER self-test.
• Is same DTC present?
Yes
Replace the PCM, then go to next step.
No
Go to next step.
10
VERIFY AFTER REPAIR PROCEDURE
• Perform the "AFTER REPAIR PROCEDURE".
• Are any DTCs present?
Yes
Go to applicable DTC troubleshooting.
No
Troubleshooting completed.
