B1367




Circuit Description
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

Conditions for Setting the DTC
Set the DTC if the voltage at the IPC connector terminal A8 is less than 3 volts for more than 1 second while the engine is running.

Conditions for Clearing the MIL/DTC
- A history DTC will clear after 100 consecutive fault free ignition cycles.
- Use a Scan Tool on order to clear history and current DTCs.

Diagnostic Aids
- An Intermittent problem may be caused by the following conditions:
- A poor connection
- A break in the wire insulation exposing 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 AB
- 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.
- The DTC 1367 may be read by the scan tool as a history code if the fuse has been recently replaced in the CKT 1020 or an open or short to ground had been repaired in the CKT 1020.
