PINPOINT TEST F : The Power Folding Mirrors Do Not Operate Correctly: Notes
Diagnostic Overview
The Power Folding Mirrors Do Not Operate Correctly
Refer to Power Mirrors for schematic and connector information.
Normal Operation and Fault Conditions
NOTE:
The power folding mirrors must be synchronized anytime the RH, LH or both mirrors are folded or unfolded without using the power folding mirror control switch, or if a new power folding mirror has been installed.
NOTE:
If the power folding mirrors are folded or unfolded continuously (6 to 10 cycles), the power lockout feature disables the system for approximately 3-10 minutes to prevent damage to the power fold motors. If this occurs, wait approximately 3 minutes with the vehicle running and up to 10 minutes with the vehicle off for the system to reset and mirror function to return to normal.
Refer to Rear View Mirrors - Exterior, Power Folding .
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| B112B | Mirror Power Fold Switch Input Short to Battery | During self-test, if a short to battery is sensed on the switch circuit, the DTC is set. During normal operation, if a fault is sensed on the circuit for greater than 2 minutes, the DTC is set as continuous. With the DTC set, any input signal on the circuit is ignored. |
Visual Inspection and Diagnostic Pre-checks
- Inspect the power folding mirror control switch.
- Inspect the power folding exterior mirror.
- Inspect for a binding or obstructed mirror.
- Power folding mirror not synchronized.
