Circuit Description
The LH mirror and the RH mirror vertical position sensors are potentiometers. The driver door module (DDM) and the passenger door module (PFDM) determine the vertical position of the mirrors based on the signal voltage from these sensors.
Conditions for Running the DTC
The door modules must be powered up and have battery voltage applied.
Conditions for Setting the DTC
The code will be set when the mirror vertical position sensor voltage is above or below the associated range limits (within 10%) for 30 seconds in the requested position. The voltage failure range limits that the module uses to set the code will vary from vehicle to vehicle and from module to module. Therefore, use the table below to determine what the failed voltage range limits are for your particular vehicle/module.
If the Mirror 5 volt reference voltage indicated on the scan tool is closest to: | the code will be set when the mirror position sensor voltage is: | the code will be set when the mirror position sensor voltage is: |
|---|---|---|
5.0 volts | 0 to 0.60 volts | 4.7 to 5.0 volts |
4.4 volts | 0 to 0.53 volts | 4.1 to 4.4 volts |
3.8 volts | 0 to 0.45 volts | 3.6 to 3.8 volts |
Action Taken When the DTC Sets
Memory movements on this axis are disabled. Manual movements are not disabled.
Conditions for Clearing the DTC
When the door modules no longer sense the failure .
Diagnostic Aids
| Important: After readjusting the mirror positions, be sure to reset the mirror memory switch to the new positions. |
| • | If this code is set as a history code, but not as a current code, remove the fuse for the door module that set the code for 10 seconds, then reinstall it. |
| • | A sticking switch may cause this DTC to set. |
Step | Action | Value(s) | Yes | No |
|---|---|---|---|---|
1 | Did you perform A Diagnostic System Check - Power Door Systems? | -- | Go to Step 2 | |
2 |
Does the scan tool indicate that the voltage increases with the Up adjustments and decreases with the Down adjustments? | -- | Go to Diagnostic Aids | Go to Step 3 |
3 |
Does the scan tool indicate the voltage is greater than the specified value? | 3.8 V | Go to Step 4 | Go to Step 8 |
4 |
Does the scan tool indicate the voltage is within the specified value? | 0-0.75 Volts | Go to Step 5 | Go to Step 8 |
5 | With a DMM, measure for voltage at the 5 volt reference pin of the module. Does the voltage measure within the specified value? | 3.50-5.00 V | Go to Step 6 | Go to Step 8 |
6 | Inspect for poor connections at the harness connector of the applicable 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 10 | Go to Step 7 |
7 | Replace the mirror . Refer to Power Mirror Replacement . Did you complete the replacement? | -- | Go to Step 10 | -- |
8 | Inspect for poor connections at the harness connector of the applicable 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 10 | Go to Step 9 |
9 | Replace the door module. Refer to Door Control Module Replacement Did you complete the replacement? | -- | Go to Step 10 | -- |
