Circuit Description

The IPC monitors the ignition 0 voltage circuit, the ignition 1 voltage circuit, and the crank voltage circuit. The ignition 0 voltage circuit is On ant the circuit is high when the ignition switch is in ACCESSORY, ON, or START. The ignition 1 circuit is active and the circuit is high when the ignition switch is in ON or START. The crank voltage circuit is On and the circuit is high when the ignition switch is in START.

Conditions for Running the DTC

The ignition is in ON or START.

Conditions for Setting the DTC
    • The IPC detects that the ignition 1 voltage circuit is On and the ignition 0 circuit is Off.
    • The IPC detects that the crank voltage circuit is On and the ignition 0 voltage circuit is Off.
    • The IPC detects that the crank voltage circuit is On and the ignition 1 voltage circuit is Off.
    • One of the above conditions is present for greater than 0.3 seconds.

Action Taken When the DTC Sets

The IPC illuminates the SERVICE VEHICLE SOON indicator.

Conditions for Clearing the DTC
    • The current DTC clears when the conditions for setting the DTC are no longer present.
    • The history DTC clears after 100 malfunction free ignition cycles.
    • The IPC receives a clear code command from the scan tool.

Diagnostic Aids

Refer to Testing for Intermittent Conditions and Poor Connections in Wiring Systems.

Did you perform the Instrument Cluster Diagnostic System Check?

Go to Step 2

Go to Diagnostic System Check - Instrument Cluster

2
  1. Install a scan tool.
  2. Turn the ignition switch to RUN.
  3. With a scan tool, observe the Ignition 1 and the Ignition 0 parameters in the IPC data list.

Does the scan tool display On for both parameters?

Go to Step 3

Go to Step 5

3
  1. Turn the ignition ON, with the engine OFF.
  2. With a scan tool, observe the Crank parameter in the IPC Data list.

Does the scan tool display No?

Go to Step 4

Go to Step 6

4
  1. Turn the ignition switch to accessory.
  2. With a scan tool, observe the Ignition 1 parameter in the IPC Data list.

Does the scan tool display Off?

Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems

Go to Step 7

5

Test the inactive ignition voltage circuit for an open, for a high resistance, or for a short to ground. Refer to Circuit Testing and to Wiring Repairs in Wiring Systems.

Did you find and correct the condition?

Go to Step 10

Go to Step 8

6

Test the crank voltage circuit of the IPC for a short to voltage. Refer to Circuit Testing and to Wiring Repairs in Wiring Systems.

Did you find and correct the condition?

Go to Step 10

Go to Step 8

7

Test the ignition 1 voltage circuit for a short to voltage. Refer to Circuit Testing and to Wiring Repairs in Wiring Systems.

Did you find and correct the condition?

Go to Step 10

Go to Step 8

8

Inspect for poor connections at the harness connector of the IPC. Refer to Testing for Intermittent Conditions and Poor Connections and to Connector Repairs in Wiring Systems.

Did you find and correct the condition?

Go to Step 10

Go to Step 9

9

Replace the IPC. Refer to Instrument Cluster Replacement .

Did you complete the replacement?

Go to Step 10
