P2317-IGNITION COIL 6 SECONDARY CIRCUIT- INSUFFICIENT IONIZATION

Special Tools:










For a complete wiring diagram, refer to the Wiring Information.

- When Monitored:
Engine running and battery voltage greater than 10.0 Volts.

- Set Condition:
If the Powertrain Control Module (PCM) detects that the secondary ignition burn time is incorrect, too short or not present, an error is detected. One Trip Fault. Three good trips to turn off the MIL.





Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. Pre-Diagnostic Troubleshooting Procedure.

1. ACTIVE DTC

NOTE: Diagnose any ASD related DTCs before continuing.

1. Start the engine.
2. With the scan tool, select View DTCs.

NOTE: It may be necessary to drive the vehicle to meet the conditions to set this DTC, try to repeat the conditions in which the fault originally set by reviewing the Freeze Frame data.

Is the DTC Active at this time?

Yes

- Go To 2

No

- Perform the INTERMITTENT CONDITION diagnostic procedure. Intermittent Condition Test.

2. (F344) ASD RELAY OUTPUT CIRCUIT




1. Turn the ignition off.
2. Disconnect the Coil on Plug harness connector.
3. Ignition on, engine not running.
4. With the scan tool, actuate the ASD Relay.
5. Using a 12-volt test light connected to ground, probe the (F344) ASD Relay Output circuit in the Coil on Plug harness connector.

Does the test light illuminate brightly?

Yes

- Go To 3

No

- Repair the open or short to ground in the (F344) ASD Relay Output circuit between the TIPM and Coil harness connector.
- Perform the POWERTRAIN VERIFICATION TEST. Powertrain Verification Test.
NOTE: Stop All Actuations.


3. IGNITION COIL





WARNING: When the engine is operating, do not stand in direct line with the fan. Do not put your hands near the pulleys, belts or fan. Do not wear loose clothing. Failure to follow these instructions may result in possible serious or fatal injury.

1. Using a 12-volt test light connected to a 12 Volt source, probe the (K10) Coil Control No. 6 circuit.
2. Crank the engine for five seconds while observing the test light.

What is the condition of the test light while cranking the engine?

Brightly blinking.

- Go To 4

ON constantly.

- Go To 5

OFF constantly.

- Go To 6

4. SPARK PLUG
1. Turn the ignition off.
2. Remove the Spark Plug(s).
3. Inspect the Spark Plug(s) for the following conditions:
- Cracks
- Carbon Tracking
- Foreign Material
- Gap size out of specifications
- Loose or broken electrode

NOTE: Lightly tap the bottom of the spark plug on a solid surface. The electrode in the spark plug should not move.

Were any of the above conditions present?

Yes

- Replace the Spark Plug.
NOTE: If carbon tracking is found on the Spark Plug, inspect the boot assembly for signs of damage and replace if necessary.

- Perform the POWERTRAIN VERIFICATION TEST. Powertrain Verification Test.

No

- Replace the Coil On Plug and Spark Plug.
- Perform the POWERTRAIN VERIFICATION TEST. Powertrain Verification Test.

5. (K10) COIL CONTROL NO. 6 CIRCUIT SHORTED TO GROUND




1. Turn the ignition off.
2. Disconnect the PCM C2 harness connector.
3. Measure the resistance between ground and the (K10) Coil Control No. 6 circuit in the Coil on Plug harness connector.

Is the resistance below 100 Ohms?

Yes

- Repair the short to ground in the (K10) Coil Control No. 6 circuit.
- Perform the POWERTRAIN VERIFICATION TEST. Powertrain Verification Test.

No

- Go To 7

6. (K10) COIL CONTROL NO. 6 CIRCUIT OPEN




1. Turn the ignition off.
2. Disconnect the PCM C2 harness connector.

CAUTION: Do not probe the PCM harness connectors. Probing the PCM harness connectors will damage the PCM terminals resulting in poor terminal to pin connection. Install the PCM Pinout Box (8815A) to perform diagnosis.

3. Measure the resistance of the (K10) Coil Control No. 6 circuit from the Coil on Plug harness connector to the appropriate terminal of the PCM Pinout Box.

Is the resistance below 5.0 Ohms?

Yes

- Go To 7

No

- Repair the open in the (K10) Coil Control NO. 6 circuit.
- Perform the POWERTRAIN VERIFICATION TEST. Powertrain Verification Test.

7. POWERTRAIN CONTROL MODULE (PCM)
1. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors between the Ignition Coil and the Powertrain Control Module (PCM).
2. Look for any chafed, pierced, pinched or partially broken wires.
3. Look for broken, bent, pushed out or corroded terminals. Verify that there is good pin to terminal contact in the Ignition Coil and the Powertrain Control Module connectors.
4. Perform any Technical Service Bulletins that may apply.

Were there any problems found?

Yes

- Repair as necessary.
- Perform the POWERTRAIN VERIFICATION TEST. Powertrain Verification Test.

No

- Replace and program the Powertrain Control Module (PCM). Powertrain Control Module - Removal.
- Perform the POWERTRAIN VERIFICATION TEST. Powertrain Verification Test.
