Driver Door Switch Scan Tool Data Parameters
| Parameter | System State | Expected Value | Description |
|---|---|---|---|
| Operating Conditions: Ignition ON | |||
| Back Only Heat Indicator | - | Off | The scan tool displays the current status of the heated seat back indicator. |
| Back Only Heat Switch | - | Inactive | The scan tool displays Active or Inactive. This is the state of the seat back heat mode switch. |
| Battery 1 (Low Current) | - | Varies | The battery 1 (low current) parameter provides the voltage level on the battery 1 input. Battery 1 is the low current input provides the power for the DDM/PDM's microprocessors and the low current outputs. |
| Battery 2 (High Current) | - | Varies | The battery 2 (high current) parameter provides the voltage level on the battery 2 input. Battery 2 is the high current input provides the power for the DDM/PDM's high current outputs such as the power windows. |
| Dimming Enable | - | Off | The scan tool displays if the dimming feature of the module is enabled or disabled. The scan tool displays On when the dimming feature of the module is enabled. |
| Dimming Potentiometer | - | Varies | The scan tool displays the duty cycle of the pulse width modulated (PWM) signal distributed by the BCM to the PWM controlled door switch backlighting based on the position of the IP dimmer switch (Thumbwheel). The scan tool displays 0 percent when the headlamp switch is in the AUTO position and the daytime running lamps (DRL) are ON or the IP dimmer switch is in the FULL DIM position. The scan tool displays 100 percent when either the headlamps or park lamps are activated and the IP dimmer switch is in the FULL BRIGHT position. |
| Door Ajar Switch | - | Off | The scan tool displays Off or On. This is the state of the door ajar switch. |
| Door Lock Motor | - | Idle | This parameter indicates the current status of the door lock motor. |
| Door Lock Switch | - | Idle | This parameter indicates the current status of the door lock switch. |
| Driver RF Window Switch | - | Idle | The scan tool displays Idle, Up, Down, Express Up or Express Down. This is the state of the driver RF Window Switch. |
| Heat Indicator High | - | Off | The scan tool displays the current status of the high heat indicator. |
| Heat Indicator Low | - | Off | The scan tool displays the current status of the low heat indicator. |
| Heat Indicator Medium | - | Off | The scan tool displays the current status of the medium heat indicator. |
| Heated Seat Switch | - | Inactive | The scan tool displays the status of the heated seat back and cushion switch. While the heated seat back and cushion switch is being pressed the scan tool will display Active, and when it is released the scan tool will display Inactive. |
| Mirror 5 Volt Reference | - | ON | The scan tool displays On or Off. This is the state of the voltage reference circuit to the mirror. |
| Mirror Fold Motor Current | - | Varies | The scan tool displays Idle, Invalid, Up, Down, Left and Right. This is the state of the mirror motor. |
| Mirror Folding Operation | - | Idle | This parameter indicates the status of the mirror folding operation. |
| Mirror Heater | - | Inactive | This parameter indicates the operational state of the mirror heater. |
| Mirror Motor | - | Idle | The scan tool displays Idle, Invalid, Up, Down, Left and Right. This is the state of the mirror motor. |
| Mirror Switch Backlight | - | Varies | The scan tool displays percentage. This is the intensity of the backlighting in the mirror switch. |
| Psgr. RF Window Switch | - | Idle | The scan tool displays Idle, Up, Down, Express Up or Express Down. This is the state of the psgr. RF window switch. |
| Window Motor Current | Varies | This parameter indicates the active status of the window lockout feature. | |
| Window Motor Output | Idle | This parameter reflects the state of the DDM/PDM output to the window motor. | |
| Window Switch Backlight | Varies | The scan tool displays the duty cycle of the pulse width modulated (PWM) signal distributed by the BCM to the PWM controlled window switch backlight based on the position of the IP dimmer switch (Thumbwheel). The scan tool displays 0 percent when the headlamp switch is in the AUTO position and the daytime running lamps (DRL) are ON or the IP dimmer switch is in the FULL DIM position. The scan tool displays 100 percent when either the headlamps or park lamps are activated and the IP dimmer switch is in the FULL BRIGHT position. | |
