11 | Repair the open circuit between the F1 fuse and the electric control mirror switch. Is the repair complete? | -- | System OK | --
12 | Inspect the left-and-right adjustment for the electric control mirror. Is the left-and-right adjustment working for the electric control mirror? | -- | Go to Step 18 | Go to Step 13
13 |

1. Verify that the electric control mirror switch has been reconnected.
2. On the passenger door, remove the black plastic escutcheon to expose the electric control mirror connector.
3. Disconnect the connector at the passenger door electric control mirror.
4. Connect a voltmeter between terminal 4 and terminal 3.
5. Observe the voltmeter while operating the electric control mirror switch to select the left-and-right adjustment.

1. Disconnect the electric control mirror switch connector.
2. Use an ohmmeter to measure the continuity between terminal 5, and the electric control mirror switch and terminal 3 at the power mirror connector.
3. Use an ohmmeter to measure the continuity between terminal 4 at the electric control mirror switch and terminal 4 at the power mirror connector.

Does the ohmmeter indicate the specified value for both measurements?

0 ohms

Go to Step 16

Go to Step 15

15 | Repair the open circuit between the electric control mirror switch and the electric control mirror connector. Is the repair complete? | -- | System OK | --
16 | Replace the electric control mirror switch. Is the repair complete? | -- | System OK | --
17 | Replace the electric control mirror. Is the repair complete? | -- | System OK | --
18 |

1. If the electric control mirror switch was previously disconnected for testing, reconnect the switch.
2. Disconnect the electric control mirror connector at the passenger door power mirror.
3. Connect a voltmeter between terminal 4 and terminal 5.
4. Observe the voltmeter while operating the power mirror switch to select the up-and-down adjustment.
