Circuit Description
There is an ignition 0 input to the instrument panel cluster (IPC). This input can be either in the on or off position from the ignition switch. If the IPC senses that the ignition 0 input 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 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 Fail 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. |
Diagnostic Aids
If the DTC is a history DTC, the problem may be intermittent. Perform the tests shown while wiggling the wiring and connectors. This can often cause the malfunction to appear. Refer to Testing for Intermittent Conditions and Poor Connections in Wiring Systems.
Test Description
The numbers listed below refer to the numbers on the diagnostic table.
Step | Action | Yes | No |
|---|---|---|---|
Schematic Reference: Instrument Cluster Schematics | |||
1 | Did you perform the IPC Diagnostic System Check? | Go to Step 2 | |
2 |
Does the scan tool display On? | Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems | Go to Step 3 |
Test the ignition 0 voltage circuit for an open or a short to ground. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 6 | Go to Step 4 | |
4 | Inspect for poor connections at the harness connector of the IPC. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 6 | Go to Step 5 |
5 |
Important: Perform the compass calibration and variance procedure on the replacement IPC. Replace the IPC. Refer to Instrument Cluster Replacement . Did you complete the replacement? | Go to Step 6 | -- |
6 |
Does the DTC reset? | Go to Step 2 | System OK |
