1 | Did you perform the Diagnostic System Check - Vehicle? | -- | Go to Step 2 | |
2 |
Does the inside rearview mirror darken? | -- | Go to Step 3 | |
3 | While shining a bright light into the sensor on the mirror face, facing the rear window, observe the driver outside rearview mirror. Does the driver outside rearview mirror darken? | -- | Go to Testing for Intermittent Conditions and Poor Connections | Go to Step 4 |
4 |
Is the voltage within the specified range? | 0.75-1.5 V | Go to Step 7 | Go to Step 5 |
5 | Is the voltage greater than the specified value? | 1.5 V | Go to Step 18 | Go to Step 6 |
6 | Measure the voltage between the signal circuit of the driver outside mirror element and a good ground. Is the voltage within the specified range? | 0.75-1.5 V | Go to Step 13 | Go to Step 12 |
7 |
Is the voltage within the specified range? | 0.75-1.5 V | Go to Step 14 | Go to Step 8 |
8 | Is the voltage greater than the specified value? | 1.5 V | Go to Step 18 | Go to Step 9 |
9 |
Is the resistance less than the specified value? | 3 ohms | Go to Step 10 | Go to Step 15 |
10 | Measure the resistance between the signal circuit of the driver outside rearview mirror element to a good ground. Is the resistance within the specified range? | OL | Go to Step 11 | Go to Step 15 |
11 | Measure the resistance of the low reference circuit of the driver outside rearview mirror element between the driver outside rearview mirror element and the DDM. Is the resistance less than the specified value? | 3 ohms | Go to Step 17 | Go to Step 15 |
12 | Test the signal circuit of the driver outside rearview mirror element for an open or short to ground. Refer to Circuit Testing and Wiring Repairs . Did you find or correct the condition? | -- | Go to Step 23 | Go to Step 16 |
13 | Test the low reference circuit of the driver outside rearview mirror element for an open or high resistance. Refer to Circuit Testing and Wiring Repairs . Did you find or correct the condition? | -- | Go to Step 23 | Go to Step 16 |
14 | Inspect for poor connections at the harness connector of the driver outside rearview mirror face. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs . Did you find or correct the condition? | -- | Go to Step 23 | Go to Step 19 |
15 | Inspect for poor connections at the harness connector of the driver outside rearview mirror. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs . Did you find or correct the condition? | -- | Go to Step 23 | Go to Step 20 |
16 | Inspect for poor connections at the harness connector of the inside rearview mirror. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs . Did you find or correct the condition? | -- | Go to Step 23 | Go to Step 21 |
17 | Inspect for poor connections at the harness connector of the DDM. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs . Did you find or correct the condition? | -- | Go to Step 23 | Go to Step 22 |
