The IPC inspects for a low Ignition 0 voltage when the engine is running. If the Ignition 0 is low, DTC B1367 is set. The Ignition 0 is a switched battery input to the IPC. The ignition should be high/hot whenever the ignition switch is in the following positions:
• | UNLOCK |
• | RUN |
• | CRANK |
The switch should be low in the following positions:
• | LOCK |
• | ACCESSORY |
The DTC sets if the voltage at the IPC connector terminal A8 is less than 3 volts for more than 1 second while the engine is running.
• | A history DTC will clear after 100 consecutive fault free ignition cycles. |
• | Use a scan tool in order to clear history and current DTCs. |
• | An Intermittent condition may be caused by the following conditions: |
- | A poor connection |
- | A break in the wire insulation that exposes the internal wire |
- | A wire broken inside the insulation |
• | The IPC odometer and the PRNDL displays will not be illuminated and the IPC will not communicate with the scan tool if the following conditions exist: |
- | The ignition 0 voltage is low at IPC connector pin A8 |
- | The engine is not running. |
• | The season odometer will display if the tripometer switch is pressed and the IPC will communicate with the scan tool until the tripometer switch is released. |
• | DTC 1367 may be read by the scan tool as a history code if the fuse was recently replaced in the CKT 1020 or an open or short to ground was repaired in the CKT 1020. |
