Test Description

WARNING: This page is about a different car, the 2004 Chevrolet Corvette. 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 tests the mirror position sensor signal voltage using a scan tool. Normal signal voltage range is between 0.1-4.78 volts.
3: This tests the mirror position sensor signal voltage using a scan tool with the mirror disconnected. Normal signal voltage range with the mirror disconnected is greater than 4.78 volts.
4: This tests the mirror position sensor signal voltage using a scan tool with the signal circuit jumpered to the sensor ground circuit. Normal signal voltage range with the sensor jumpered to ground is less than 0.1 volt.

DTC B2262-B2265

1	Did you perform the Door Systems Diagnostic System Check?	-	Go to Step 2	Go to Diagnostic System Check - Door Systems
2	Install a scan tool. Turn ON the ignition, with the engine OFF. With a scan tool, observe the appropriate mirror position parameter in the appropriate door control module data list. Does the scan tool indicate that the mirror position parameter is within the specified range?	0.1-4.78 V	Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems	Go to Step 3
3	Turn OFF the ignition. Disconnect the appropriate mirror. Turn ON the ignition, with the engine OFF. With a scan tool, observe the appropriate mirror position parameter in the appropriate door control module data list. Does the scan tool indicate that the mirror position parameter is greater than the specified value?	4.78 V	Go to Step 4	Go to Step 5
4	Turn OFF the ignition Connect a 3-amp fused jumper wire between the signal circuit of the appropriate mirror position sensor and the ground circuit of the appropriate mirror position sensor. Turn ON the ignition, with the engine OFF. With a scan tool, observe the appropriate mirror position parameter in the appropriate door control module data list. Does the scan tool indicate that the mirror position parameter is less than the specified value?	0.1 V	Go to Step 7	Go to Step 6
5	Test the appropriate mirror position signal circuit for a short to ground. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition?	-	Go to Step 11	Go to Step 8
6	Test the appropriate mirror position signal circuit for a high resistance or an open. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition?	-	Go to Step 11	Go to Step 8
7	Inspect for poor connections at the harness connector of the appropriate mirror. 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 11	Go to Step 9
8	Inspect for poor connections at the harness connector of the appropriate door module. 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 11	Go to Step 10
9	Replace the appropriate mirror. Refer to Mirror Replacement . Did you complete the replacement?	-	Go to Step 11	-
10	Replace the appropriate door module. Refer to Door Control Module Replacement . Did you complete the replacement?	-	Go to Step 11	-
11	Use the scan tool in order to clear the DTCs. 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
