For 1990-2009 cars

### Circuit Description

The rear integration module (RIM) monitors the voltage input of the hood open switch signal circuit and the hood open closed switch signal circuit. During proper operation, the 2 separate voltage signals at the RIM should never be the same voltage with the hood opened or closed. If the 2 voltage signal should have the same voltage value DTC B3006 will set.

### DTC Descriptor

This diagnostic procedure supports the following DTC:

DTC B3006 Hood Ajar Circuit

The vehicle has DTCs including the DTC symptoms. Refer to DTC Symptom Description for more DTC information.

DTC Symptom | DTC Symptom Descriptor
--- | ---
5A | Seeming Faults

### Conditions for Running the DTC

This DTC shall run when the Run/Crank Relay is enabled.

### Conditions for Setting the DTC

If both the hood open switch signal circuit and the hood closed switch signal circuit are simultaneously in a high or low voltage state.

### Action Taken When the DTC Sets

• | Remote start functions will be disabled.

• | The hood ajar switch inputs will be ignored by content theft deterrent (CTD).

### Conditions for Clearing the MIL/DTC

When conditions for the DTC to set no longer exist, the DTC will be cleared.

### Test Description

The number below refers to the step number on the diagnostic table.

1. Turn on the ignition switch, and do not start the engine.
2. Disconnect the hood ajar switch.
3. Measure the voltage from the hood ajar switch open signal circuit to the ground circuit of the hood ajar switch.

Is the voltage measured greater than the specified value?

10V

Go to Step 3

Go to Step 4

3 | Measure the voltage from the hood ajar switch closed signal circuit to a good ground. Is the voltage measured greater than the specified value? | 10V | Go to Step 8 | Go to Step 6
4 | Measure the voltage from the hood ajar switch open signal circuit to a good ground. Is the voltage measured greater than the specified value? | 10V | Go to Step 7 | Go to Step 5
5 | Test the hood open switch signal circuit of the hood ajar switch for the following:

• | Short to Ground

• | An open circuit

• | High resistance

Refer to Circuit Testing .

Did you find and correct the condition?

Go to Step 12

Go to Step 9

6 | Test the hood closed switch signal circuit of the hood ajar switch for the following:

• | Short to Ground

• | An open circuit

• | High resistance

Refer to Circuit Testing .

Did you find and correct the condition?

--

Go to Step 12

Go to Step 9

7 | Repair the ground circuit of the hood ajar switch. Refer to Wiring Repairs . Is the repair complete? | -- | Go to Step 12 | --
8 | Inspect for poor connections at the harness connector of the hood ajar switch. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs . Did you find and correct the condition? | -- | Go to Step 12 | Go to Step 10
9 | Inspect for poor connections at the harness connector of the hood ajar switch. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs . Did you find and correct the condition? | -- | Go to Step 12 | Go to Step 11
10 | Replace the hood ajar switch. Refer to Hood Ajar Indicator Lamp Switch Replacement . Is the replacement complete? | -- | Go to Step 12 | --
11 | Replace the Rear Integration Module (RIM). Refer to 148097 . Is the replacement complete? | -- | Go to Step 12 | --
