P1361

CIRCUIT DESCRIPTION
The ignition control (IC) module has independent power and ground circuits. The circuits between the IC module and the powertrain control module (PCM) consist of the following circuits:
^ The IC timing signal
^ The IC timing control
^ The low-resolution engine speed signal A low reference signal

The ignition control (IC) module sends 3x signals to the powertrain control module (PCM). The IC module controls the timing advance during engine cranking. The timing advance changes to PCM control after the following actions:
^ The PCM receives the second 3x signal.
^ The PCM applies 5 volts to the IC timing signal circuit.
^ The timing advance switches to PCM control.

CONDITIONS FOR RUNNING THE DTC
^ The engine speed is more than 600 RPM.
^ DTC P1351 did not set.

CONDITIONS FOR SETTING THE DTC
^ The PCM does not monitor IC pulses while IC mode spark advance is commanded.
^ The condition is present for 300 3X reference periods, 100 crankshaft revolutions.

ACTION TAKEN WHEN THE DTC SETS
^ The control module illuminates the malfunction indicator lamp (MIL) on the second consecutive ignition cycle that the diagnostic runs and fails.
^ The control module records the operating conditions at the time the diagnostic fails. The first time the diagnostic fails, the control module stores this information in the Failure Records. If the diagnostic reports a failure on the second consecutive ignition cycle, the control module records the operating conditions at the time of the failure. The control module writes the operating conditions to the Freeze Frame and updates the Failure Records.

CONDITIONS FOR CLEARING THE MIL/DTC
^ The control module turns OFF the malfunction indicator lamp (MIL) after 3 consecutive ignition cycles that the diagnostic runs and does not fail.
^ A current DTC, Last Test Failed, clears when the diagnostic runs and passes.
^ A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other emission related diagnostic.
^ Clear the MIL and the DTC with a scan tool.
