Volkswagen Code P1355 – Ignition Activation Circuit Cylinder 1 Open

Possible Causes

NOTE: The listed causes may not be a complete list of all potential problems and there may be other causes.

Faulty cylinder 1 ignition coil
Cylinder 1 ignition coil harness is open or shorted
Poor electrical connection in cylinder 1 ignition coil circuit
Faulty Engine Control Module (ECM)

Technical Notes

Volkswagen Golf, Jetta, New Beetle 2002-2004

Description

The Engine Control Module (ECM) must determine if a misfire is occurring and identify the specific cylinder(s) and severity of the misfire event and whether it is emissions relevant or damaging to the catalyst. To accomplish these tasks, the control module monitors the crankshaft for acceleration losses during the firing segments of each cylinder according to the firing order.
The misfire/engine roughness calculation is derived from the differences in period duration (T) of individual increment gear segments. Each segment period consists of an angular range of 120° of crankshaft angle that begins 78° before Top Dead Center (TDC).
If the expected period duration is greater than the allowed value, a misfire fault for the particular cylinder is recorded in the ECM fault memory. Depending on the measured misfire rate level, the control unit illuminates the “Service Engine Soon” light, may cut fuel to the particular cylinder, and may switch lambda operation to open loop. All misfire faults are weighted to determine whether the misfire is emissions relevant or damaging to the catalyst.

To accomplish these tasks, the control module monitors the crankshaft for acceleration losses during the firing segments of each cylinder according to the firing order.

If the expected period duration exceeds the allowed value, a misfire fault for that particular cylinder is recorded in the ECM’s fault memory. Depending on the measured misfire rate level, the control unit illuminates the “Service Engine Soon” light, may cut fuel to the particular cylinder, and may switch lambda operation to open loop. All misfire faults are weighted to determine whether the misfire is relevant for emissions or damaging to the catalyst.

BMW Code P1356 – Cylinder 8 Misfire on Start

Possible Causes

NOTE: The listed causes may not be a complete list of all potential issues and there may be other causes.

Faulty spark plug
Faulty ignition coil
Intake vacuum leak
Faulty camshaft position sensor
Ignition coil harness is open or shorted
Poor electrical connection in ignition coil circuit

Description

Under CARB/OBD regulations, the Engine Control Module (ECM) must determine if a misfire is occurring and also identify the specific cylinder(s) and severity of the misfire event, and whether it is emissions-relevant or damaging to the catalyst. To accomplish these tasks, the control module monitors the crankshaft for acceleration losses during the firing segments of each cylinder according to the firing order.
The misfire/engine roughness calculation is derived from differences in period duration (T) of individual increment gear segments. Each segment period consists of a 120° angular range of crankshaft angle starting 78° before top dead center (TDC).
If the expected period duration exceeds the allowed value, a misfire fault for that particular cylinder is recorded in the ECM’s fault memory. Depending on the measured misfire rate level, the control unit illuminates the Service Engine Soon light, may cut fuel to the particular cylinder, and may switch lambda operation to open loop. All misfire faults are weighted to determine whether the misfire is emissions-relevant or damaging to the catalyst.

Chevrolet Code P1356 – Ignition Control Module High Output/Pulse Detected When Cylinder 6 is Grounded

Possible Causes

NOTE: The listed causes may not be a complete list of all potential problems and there may be other causes.

Faulty ignition control module
Ignition control module harness is open or shorted
Poor electrical connection in the ignition control module circuit

Description

The ignition control module (ICM) has independent power and ground circuits.

The circuits between the ICM and the powertrain control module (PCM) consist of the following circuits:

– Ignition control (IC) timing signal

– IC timing control

– Low resolution engine speed signal

– Medium resolution engine signal

– Camshaft position signal

– Low referenceThe ICM sends 3X signals to the PCM and controls ignition timing during engine starting.

Timing advance switches to PCM control after the following actions occur:

The PCM receives the second 3X signalThe PCM applies 5 volts to the ignition control (IC) timing signal circuit.

The ICM monitors the CKP timing signal when the engine starts. The CKP timing signal is transmitted from the CKP sensor to the ICM on the CKP sensor signal 2 circuit.

The CKP timing signal is used to determine the correct cylinder pair and initiate the ignition coil firing sequence.

The 18X reference pulses are transmitted from the CKP sensor to the ICM on the CKP sensor 1 circuit.

The 18X reference pulses are used for fuel injection and ignition control.

Once the ICM has received both signals, the ICM transmits the 18X and 3X reference signals to the PCM.

The CMP and CKP sensors share a 12-volt reference circuit and a low reference circuit.

The CKP sensor consists of the following circuits:

– A 12-volt reference

– A low reference

– A CKP sensor signal 1

– A CKP sensor signal 2
