P1352 Cadillac Code – Ignition Control Module High/Impulse Output Detected When Cylinder 2 is Grounded

Possible Causes

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

  • Ignition coil “A” harness is open or shorted
  • Poor electrical connection in ignition coil “A” circuit

Description

How to Repair

Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector pins.

Possible Symptoms

  • Engine light on (or service engine soon warning light)

GMC Code P1352 – Ignition Control Module High Pulse Output Detected When Cylinder 2 is Grounded

Possible Causes

NOTE: This list is not exhaustive and other issues may be causing the situation.

  • Faulty ignition control module (ICM)
  • Open or shorted ICM wiring harness
  • Faulty electrical connection in the ICM circuit

Description

The ignition control module (ICM) has independent power and ground circuits. The connections between the ICM and the powertrain control module (PCM) include:

  • The ignition control (IC) synchronization signal
  • The IC synchronization control
  • Low and medium resolution engine speed signals
  • Camshaft position signal
  • A low reference

The ICM transmits 3X signals to the PCM and manages timing advance during engine startup. Once the following steps are completed, timing advance management switches to the PCM:

  1. The PCM receives a second 3X signal.
  2. The PCM applies a 5-volt voltage to the IC synchronization signal circuit.

During startup, the ICM monitors the CKP synchronization signal sent by the CKP sensor via the corresponding circuit. This signal is used to identify the correct cylinder pair and trigger ignition.

The CKP sensor also sends 18X reference pulses to the ICM. These pulses are essential for fuel injection and ignition control. Once both signals are received, the ICM transmits them as 18X and 3X references to the PCM.

The CMP (camshaft) and CKP (crankshaft) sensors share:

  • A 12-volt power supply
  • A low reference

The CKP sensor circuits include:

  • A 12-volt power supply
  • A low reference
  • A CKP 1 signal
  • A CKP 2 signal

How to Repair

  1. Check the possible causes mentioned above.
  2. Visually inspect the wiring harness and associated connectors.
  3. Look for damaged components, as well as broken, bent, displaced, or corroded connector pins.

Diagnostic

The PCM detects a break in the ignition control module (ICM).

Possible Symptoms

  • Engine light on (or maintenance required light).

Code P1353 – Cylinder 6 Misfire with Fuel Cutoff

Possible Causes

NOTE: The listed causes may not be a complete list of all potential problems 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 based on 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° crankshaft angle range 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.

How to Repair

Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector pins.

Possible Symptoms

  • Engine Light On (or Service Engine Soon Warning Light)
