1. the engine cranks but does not run and opens the fuse F9 that supplies voltage to the ignition coil. 2. The engine cranks but does not run. |
Ignition voltage is supplied to the ignition coil. The engine control module (ECM) provides an ground for the ignition coil control circuits. When the ECM removes the ground path of the ignition primary coil, the magnetic field produced by the coil collapses. The collapsing magnetic field produces a voltage in the secondary coil which ignites the spark plugs. The sequencing and timing are controlled by the ECM.
• | The engine is running. |
• | The ignition voltage is greater than 6 V. |
• | The DTC runs continuously once the above condition is met. |
The ECM detects that the commanded state of the driver and the actual state of the control circuit do not match for greater than 5 s.
DTCs P0351 00, P0352 00, P0353 00 and P0354 00 are Type B DTCs.
DTCs P0351 00, P0352 00, P0353 00 and P0354 00 are Type B DTCs.
The following conditions can also set the DTC:
• | Inspect the ignition coils for aftermarket devices. An aftermarket device connected to the ignition coil circuits, may cause this DTC to set. |
• | The MIL indicator flashes when there is an engine misfire. |
• | If the condition is intermittent, moving the related harnesses and connectors, with the engine operating, while monitoring the appropriate scan tool Misfire Current Cylinder parameter may help to isolate the condition. |

Control Module References for scan tool information
⇒ | If greater than the specified range, repair the ground circuit for an open/high resistance. |
⇒ | If greater than the specified range, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the K20 Engine Control Module. |
⇒ | If the test lamp does not illuminate, test the ignition voltage circuit for a short to ground or an open/high resistance. If the circuit tests normal and the ignition voltage circuit fuse F9 is open, test all components connected to the ignition voltage circuit and replace as necessary. |
Note: Set the DMM to the DC Hertz scale for this test.
• | Ignition coil 1 control terminal D |
• | Ignition coil 2 control terminal E |
• | Ignition coil 3 control terminal F |
• | Ignition coil 4 control terminal G |
⇒ | If less than the specified range, test the ignition control circuit for a short to voltage, short to ground, or an open/high resistance. If the circuit tests normal, replace the K20 Engine Control Module. |
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
