1. Driver Information Center (DIC) Switch Malfunction

### Circuit/System Description

The driver information center (DIC) switch is a multiplexed switch. The DIC switch is a momentary contact switch that connects a series of resistors in a resistor ladder format. The DIC switch signal circuit is pulled up to battery voltage in the IPC. The IPC also provides the DIC switch with a low reference. The switch input to the IPC is pulled low when a switch is activated. The IPC monitors the DIC switch signal circuit to determine the DIC switch inputs. Each switch state - Set/Reset, Vehicle Information, Personalization - corresponds to a certain resistance value. The IPC determines the switch pressed by the voltage drop across the resistors.

The Trip/Fuel switch is monitored on a separate circuit provided by the IPC. The Trip/Fuel switch signal circuit is monitored for a stuck switch but not a short to battery.

### Conditions for Running the DTC

The ignition is in ACCESSORY or RUN.

### Conditions for Setting the DTC

#### B3567 59

The IPC detects that the DIC switch is stuck.

#### B3567 01

The IPC detects that the DIC switch signal circuit is shorted to battery.

### Action Taken When the DTC Sets

The IPC ignores the DIC switch inputs.

### Conditions for Clearing the DTC

• | The DTC becomes history when the conditions for setting the DTC are no longer present.

• | The history DTC clears after 40 malfunction-free warm-up cycles.

### Diagnostic Aids

• | When the Trip/Fuel switch is stuck, all other DIC switches will function correctly. When any of the DIC switches are stuck, only the Trip/Fuel switch functions correctly.

• | Only the DIC switch signal circuit can be diagnosed as shorted to battery.

### Circuit/System Testing

1. Ignition OFF, disconnect the harness connector at the driver information center (DIC) switch.
2. Ignition OFF, test for less than 1 ohm between the low reference circuit terminal 1 and ground.

⇒ | If greater than the specified value, test the low reference circuit for an open/high resistance.

3. Ignition OFF, test for less than 5 ohms between the ground circuit terminal 5 and ground.

⇒ | If greater than the specified value, test the ground circuit for an open/high resistance.

4. Ignition ON, test for B+ between the switch signal circuit terminal 2 and ground.

⇒ | If less than the specified value, test the signal circuit for a short to ground. If the circuit tests normal, test or replace the IPC.

⇒ | If greater than the specified value, test the signal circuit for a short to voltage. If the circuit tests normal, test or replace the IPC.

5. Ignition ON, verify a test lamp illuminates between the signal circuit terminal 2 and ground.

⇒ | If the test lamp does not illuminate, test the signal circuit for an open/high resistance. If the circuit tests normal, replace the IPC.

6. Ignition ON, test for B+ between the signal circuit terminal 3 and ground.

⇒ | If less than the specified value, test the signal circuit for a short to ground. If the circuit tests normal, test or replace the IPC.

⇒ | If greater than the specified value, test the signal circuit for a short to voltage. If the circuit tests normal, test or replace the IPC.

7. Ignition ON, verify a test lamp illuminates between the signal circuit terminal 3 and ground.

⇒ | If the test lamp does not illuminate, test the signal circuit for an open/high resistance. If the circuit tests normal, replace the IPC.

8. If all circuits test normal, test or replace the DIC switch.
