Test Description

WARNING: This page is about a different car, the 2007 Pontiac Montana SV6, 2007 Chevrolet Uplander, and 2007 Buick Terraza. However, it is still accessible from the selected car via links, so may be relevant.

The numbers below refer to the step numbers on the diagnostic table.

2: This step tests for the proper voltage output on the 5-volt reference circuit and the proper operation of the signal circuit.
3: This step tests for possible low 5-volt reference output or a problem with the signal circuit.
4: This step tests for a short to voltage on the 5-volt reference circuit. If a short to voltage exists, other DTCs may be set for the vehicle stability system.
8: This step tests for a problem with the low reference circuit. If a short to voltage exists, other DTCs may be set for the vehicle stability system.

1	Did you perform the Diagnostic System Check - Vehicle?	-	Go to Step 2	Go to Diagnostic System Check - Vehicle
2	Turn OFF the ignition. Disconnect the yaw and lateral acceleration sensor harness connector. Connect a 3-amp fused jumper wire between the 5-volt reference circuit of the yaw and lateral acceleration sensor and the signal circuit of the yaw and lateral acceleration sensor. Turn ON the ignition, with the engine OFF. With the scan tool, observe the yaw rate signal voltage. Does the scan tool indicate that the yaw rate signal parameter is in between the specified voltage range?	4.5-5.5 V	Go to Step 8	Go to Step 3
3	With the 3-amp fused jumper wire still connected, does the scan tool indicate that the yaw rate sensor parameter is below the specified voltage value?	4.5 V	Go to Step 5	Go to Step 4
4	Test the 5-volt reference circuit of the yaw and lateral acceleration sensor for a short to voltage. Refer to Circuit Testing and Wiring Repairs . Did you find and correct the condition?	-	Go to Step 12	Go to Step 7
5	Test the 5-volt reference circuit of the yaw and lateral acceleration sensor for the following conditions: An open A short to ground A high resistance Refer to Circuit Testing and Wiring Repairs . Did you find and correct the condition?	-	Go to Step 12	Go to Step 6
6	Test the yaw rate signal circuit for the following conditions: An open A short to ground A high resistance Refer to Circuit Testing and Wiring Repairs . Did you find and correct the condition?	-	Go to Step 12	Go to Step 11
7	Test the yaw rate signal circuit for a short to voltage. Refer to Circuit Testing and Wiring Repairs . Did you find and correct the condition?	-	Go to Step 12	Go to Step 11
8	Test the low reference circuit of the yaw and lateral acceleration sensor for the following conditions: An open A short to voltage A high resistance Refer to Circuit Testing and Wiring Repairs . Did you find and correct the condition?	-	Go to Step 12	Go to Step 9
9	Inspect for poor connections at the harness connector of the yaw and lateral acceleration sensor. 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
10	Replace the yaw and lateral acceleration sensor. Refer to Yaw Rate Sensor/Lateral Accelerometer Replacement . Did you complete the replacement?	-	Go to Step 12	-
11	Replace the electronic brake control module (EBCM). Refer to Control Module References for replacement, setup, and programming. Did you complete the replacement?	-	Go to Step 12	-
12	Clear the DTCs using the scan tool. Operate the vehicle within the Conditions for Running the DTC as specified in the supporting text. Does the DTC reset?	-	Go to Step 2	System OK
