DTC P0352 | Ignition coil No.2 control circuit malfunction
--- | ---
DETECTION CONDITION | • If the PCM detects an abnormal voltage value when ignition coil No.2 is energized under the following monitoring conditions, the PCM determines that the ignition coil No.2 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.2 terminal A and PCM terminal 2A • Open circuit between ignition coil No.2 terminal C and PCM terminal 2U • Short to power or ground between ignition coil No.2 terminal C and PCM terminal 2U • PCM malfunction

Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | PERFORM DTC CONFIRMATION PROCEDURE • Perform the DTC CONFIRMATION PROCEDURE. (See DTC CONFIRMATION PROCEDURE.) • Is the same DTC present? | Yes | Go to the next step.
No | Intermittent concern exists. Go to the INTERMITTENT CONCERN TROUBLESHOOTING procedure. (See INTERMITTENT CONCERN TROUBLESHOOTING.)
2 | INSPECT IGNITION COIL NO.2 FOR POOR CONNECTION • Turn the ignition switch off. • Disconnect the ignition coil No.2 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.
3 | INSPECT IGNITION COIL NO.2 FOR ELECTRICAL MALFUNCTION • Inspect ignition coil No.2. (See IGNITION COIL INSPECTION [ZJ, ZY].) • Is ignition coil No.2 normal? | Yes | Go to the next step.
No | Replace ignition coil No.2, then go to Step 10.
4 | INSPECT CONTROL CIRCUIT FOR SHORT TO POWER • Turn the ignition switch to the ON position (Engine off). • Measure the voltage between the following terminal and body ground: - Ignition coil No.2 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.
5 | INSPECT CONTROL CIRCUIT FOR SHORT TO GROUND • Turn the ignition switch off. • Inspect for continuity between the following terminal and body ground: - Ignition coil No.2 terminal C (wiring harness-side) • Is there continuity? | Yes | Repair or replace the wiring harness, then go to Step 10.
No | Go to the next step.
6 | 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.
7 | INSPECT CONTROL CIRCUIT MALFUNCTION FOR OPEN CIRCUIT • Inspect for continuity between the following terminals: - Between ignition coil No.2 terminal C (wiring harness-side) and PCM terminal 2U (wiring harness-side) • Is there continuity? | Yes | Go to the next step.
No | Repair or replace the wiring harness, then go to Step 10.
8 | INSPECT POWER CIRCUIT MALFUNCTION FOR OPEN CIRCUIT • Inspect for continuity between the following terminals: - Between ignition coil No.2 terminal A (wiring harness-side) and PCM terminal 2A (wiring harness-side) • Is there any 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 terminal and body ground: - Ignition coil No.2 terminal B (wiring harness-side) • Is there continuity? | Yes | Go to the next step.
No | Repair or replace the wiring harness, then go to the next step.
10 | VERIFY TROUBLESHOOTING OF DTC P0351, P0352, P0353 AND P0354 COMPLETED • Make sure to reconnect all disconnected connectors. • Clear the DTC using the WDS or equivalent. • Perform the KOER self-test. (See KOEO/KOER SELF-TEST.) • Is the same DTC present? | Yes | Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION.)
No | Go to the next step.
11 | VERIFY AFTER REPAIR PROCEDURE • Perform the "AFTER REPAIR PROCEDURE". (See AFTER REPAIR PROCEDURE.) • Are any DTCs present? | Yes | Go to the applicable DTC troubleshooting. (See DTC TABLE.)
No | Troubleshooting completed.
