DTC B1369

DTC Descriptor

DTC B1369
- Device Ignition 0 (UNLOCK, ON, and START) Circuit Open

Diagnostic Fault Information

Perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure. Initial Inspection and Diagnostic Overview






Circuit Description

The instrument panel cluster (IPC) monitors the ignition 0 voltage circuit when the ignition switch is in either the ON position or the OFF position. If the IPC senses that the ignition 0 voltage circuit is low for greater than 3 seconds, DTC B1369 is set.

Conditions for Running the DTC

* The ignition switch is ON.
* At least 3 seconds has elapsed since the ignition switch was cycled ON.

Conditions for Setting the DTC

The ignition 0 input is low during power up or while in RUN for greater than 3 seconds.

Action Taken When the DTC Sets

* The IPC stores DTC B1369 in memory.
* The IPC will store conditions which were present when the DTC set as Failure Records data only. The information will not be stored as Freeze Frame data.

Conditions for Clearing the DTC

* A current DTC B1369 will clear when the malfunction is no longer present and the ignition switch is cycled.
* A history DTC B1369 will be cleared after 100 ignition cycles with no current codes active during the 100 ignition cycles.
* The IPC receives the clear code command from the scan tool.

Circuit/System Testing

1. Ignition ON, engine OFF, verify the scan tool Ignition 0 parameter displays On.

• If not On, test the ignition 0 voltage circuit for an open/high resistance or a short to ground. If the circuit tests normal, replace the IPC.

2. If all circuits test normal, replace the IPC.
