I have a P0353 DTC, replaced all coils, reset DTC and the same one came back.

I'm now testing all the wiring for coil #3 and need a pin out chart for the PCM so I can check continuity from the ground side of the connector back to the PCM connector.

Thanks in advance,
Mike

Hi,

I attached and highlighted the wire to the PCM (left rear of eng compartment). Also, the gray wire goes to fuse 43 in the battery junction box. See pic 2.

Pic 3 shows fuse 43 in box.

If you look at pic 4, it shows possible causes for the code. Here are the diagnostics for this type of failure.

JF: Introduction See: Computers and Control Systems > Pinpoint Tests > JF: Integrated Ignition Coil On Plug Coil A Through J Failure - Introduction

JF1 DETERMINE WHICH COIL IS NOT FIRING PROPERLY

Note:Electronic ignition engine timing is entirely controlled by the PCM. Electronic ignition timing is NOT adjustable. Do not attempt to check base timing. You will receive false readings.

- Determine which coil is not firing properly using the information from Pinpoint Test JB or a DTC and the table at the beginning of this pinpoint test.

- Record the suspect cylinder, coil and PCM pin number from the table.
Is the suspect cylinder number, coil driver and PCM pin number recorded?
Yes

- GO to JF2.

No

- REPEAT the test step to obtain the required information.

JF2 CHECK THE FUNCTIONALITY OF THE SUSPECT COIL DRIVER CIRCUIT

- Suspect coil connector disconnected.

- Connect a non-powered test lamp between the IGN START/RUN and suspect coil driver, harness side.

- Disable the fuel pump by disconnecting the inertia fuel shutoff switch.

- Observe the test lamp while cranking the engine.
Is the test lamp blinking consistently?
Yes

- GO to JF3.

No

- GO to JF4.

JF3 CHECK THE FUNCTIONALITY OF THE SUSPECT COIL

- Ignition OFF.

- Carry out a visual inspection. Closely inspect the coil case and boot for carbon tracking, cracks and torn or improperly installed boots.

- Remove the suspect COP from the spark plug.

- Connect the Air Gap spark tester 303-DO37 (D81P-6666-A) or its equivalent in series between the suspect coil tower and the spark plug wire.

- Suspect coil connector connected.

- Observe the spark tester while cranking the engine.
Is a bluish-white spark present?
Yes

- GO to Pinpoint Test Z See: Computers and Control Systems > Diagnostic Trouble Code Tests and Associated Procedures > Z: Intermittent - Introduction.

- INSTALL a new suspect coil. If necessary, INSTALL a new spark plug.
REFER to Ignition System.

- CLEAR the DTCs. Repeat the self-test.

JF4 CHECK THE IGNITION START/RUN VOLTAGE TO THE SUSPECT COIL

- Ignition ON, engine OFF.

- Suspect coil connector disconnected.

- Measure the voltage between:

image

Is the voltage greater than 10 V?

- For All others

- REPAIR the open circuit.

- CLEAR the DTCs. REPEAT the self-test.

JF5 CHECK THE SUSPECT COIL DRIVER CIRCUIT FOR AN OPEN IN THE HARNESS

- Ignition OFF.

- PCM connector disconnected.

- Suspect coil connector disconnected.

- Measure the resistance between:

image

- GO to JF6.

No

- REPAIR the open circuit. CLEAR the DTCs. REPEAT the self-test.

JF6 CHECK THE SUSPECT COIL DRIVER CIRCUIT FOR A SHORT TO VOLTAGE IN THE HARNESS

- Ignition ON, engine OFF.

- Measure the voltage between:

image

Is the voltage less than 1 V?
Yes

- GO to JF7.

No

- REPAIR the short circuit to PWR. CLEAR the DTCs. REPEAT the self-test.

JF7 CHECK THE SUSPECT COIL DRIVER CIRCUIT FOR A SHORT TO GROUND IN THE HARNESS

- Ignition OFF.

- Measure the resistance between:

image

Is the resistance greater than 10K ohms?
Yes

- GO to JF14.

No

- REPAIR the short circuit to GND. CLEAR the DTCs. REPEAT the self-test. If the concern or DTC is still present,

- GO to JF8.

JF8 CHECK THE SUSPECT COIL FOR DAMAGE

- PCM connector connected.

- Connect the Air Gap spark tester 303-DO37 (D81P-6666-A) or its equivalent in series between the suspect coil tower and the spark plug wire.

- Locate and activate the fuel inertia switch to disable fuel pump.

- Observe the spark tester while cranking the engine.
Is a bluish-white spark present?
Yes

- If necessary, INSTALL a new spark plug. REFER to Ignition System.

- CLEAR the DTCs. REPEAT the self-test.

No

- INSTALL a new suspect coil. REFER to Ignition System.

- CLEAR the DTCs. REPEAT the self-test.

JF9 CHECK VPWR CIRCUIT CONTINUITY BETWEEN THE SUSPECT COIL AND IGNITION COILS RELAY

- Ignition OFF.

- Ignition Coils Relay connector disconnected.

- Measure the resistance between:

image

Is the resistance less than 5 ohms?
Yes

- GO to JF10.

No

- REPAIR the open circuit.

- The open is between the splice and the ignition coils relay.

- CLEAR the DTCs. REPEAT the self-test.

JF10 CHECK THE B+ AND IGN START/RUN VOLTAGE TO THE IGNITION COILS RELAY

- Ignition ON, engine OFF.

- Measure the voltage between:

image

Are the voltages greater than 10 V?
Yes

- GO to JF11.

No

- REPAIR the open circuit. CLEAR the DTCs. REPEAT the self-test.

JF11 CHECK THE IGNITION COILS RELAY CIRCUIT FOR AN OPEN IN THE HARNESS

- Measure the voltage between:

image

Is the voltage greater than 10 V?
Yes

- GO to JF12.

No

- REPAIR the open circuit. CLEAR the DTCs. REPEAT the self-test.

JF12 CHECK THE IGNITION COILS RELAY

- Carry out the ignition coils relay component test.
Is a concern present?
Yes

- INSTALL a new Ignition Coils relay. CLEAR the DTCs. REPEAT the self-test.

No

- GO to JF13.

JF13 TEST DIRECTION FOR PINPOINT TEST A

Were you directed to this pinpoint test from pinpoint test step A8?
Yes

- GO to A9 See: Computers and Control Systems > Diagnostic Trouble Code Tests and Associated Procedures > A: No Start - Pinpoint Test.

No

- GO to JF14.

JF14 CHECK FOR CORRECT PCM OPERATION

- Disconnect all the PCM connectors.

- Visually inspect for:
- pushed out pins.
- corrosion.
- Connect all the PCM connectors and make sure they seat correctly.

- Carry out the PCM self-test and verify the concern is still present.
Is the concern still present?
Yes

- INSTALL a new PCM. REFER to Section 2, Flash Electrically Erasable Programmable Read Only Memory (EEPROM) See: Computers and Control Systems > Diagnostic Trouble Code Tests and Associated Procedures > Flash Electrically Erasable Programmable Read Only Memory (EEPROM).

No

- The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.

Hi,

I am going to relist the directions and the images. I felt this would make it easier to follow. Also, I'm not sure why I didn't add them originally. Sorry about that.
