P1362

CIRCUIT DESCRIPTION
The Ignition Control Module (ICM) has independent power and ground circuits. The circuits between the ICM and the Powertrain Control (PCM) Module consists of the following circuits:
^ The IC timing signal
^ The IC timing control
^ The low resolution engine speed signal
^ The medium resolution engine signal
^ The camshaft position signal
^ The low reference

Both the Camshaft Position (CMP) sensor and Crankshaft Position (CKP) sensor signals are input directly to the ICM. The ICM sends 3X signals to the PCM, and controls the timing advance during engine cranking. The timing advance changes 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.

CONDITIONS FOR RUNNING THE DTC
The engine is running.

CONDITIONS FOR SETTING THE DTC
The PCM detects a short to voltage in the IC timing signal circuit.

ACTION TAKEN WHEN THE DTC SETS
^ First failure:
- The MIL is not turned ON.
- A DTC is stored in memory under Failed Last Test.
- The Failure Records are stored.
^ Second consecutive drive cycle with a failure:
- The MIL is turned ON.
- A DTC is stored in memory under history.
- The Freeze Frame data is stored.
- The Failure Records are stored.

CONDITIONS FOR CLEARING THE MIL/DTC
^ The control module turns OFF the Malfunction Indicator Lamp (MIL) after the third consecutive trip the diagnostic has run and passed.
^ The history DTC will clear if the fault conditions have not been detected for 40 warm-up cycles.
^ A scan tool can be used to clear DTC information.

TEST DESCRIPTION

Steps 1-8:




Steps 9-16:




The number below refers to the step number on the diagnostic table.
2. This step determines if DTC P1361 is also set.
