Pinpoint Test E : C1007:11, C1007:12, C1007:13, C1007:19: Notes
Refer to Retractable Running Boards for schematic and connector information.
Normal operation and Fault Conditions
The RBM determines the need to move the RHPRB and applies voltage and ground on only 2 circuits to the PRB motor in order to stow (retract) or deploy (extend) the PRB. To stow the PRB, the RBM applies voltage on the RIGHT RB STOW circuit and ground on the RIGHT RB DEPLOY circuit. To deploy the PRB the RBM switches the voltage and ground so the voltage is applied to the RIGHT RB DEPLOY circuit and ground to the RIGHT RB STOW circuit. The RBM monitors the PRB motor current draw while it is operating. These Diagnostic Trouble Codes (DTCS) will set if the circuits are interrupted or if the PRB motor current is above 45 Amps.
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| C1007:11 | Right Power Running Board Motor: Circuit Short To Ground | This DTC sets if the RHPRB motor stow or deploy circuit is shorted to ground when a movement is requested. |
| C1007:12 | Right Power Running Board Motor: Circuit Short To Battery | This DTC sets if the RHPRB motor stow or deploy circuit is shorted to voltage when a movement is requested. |
| C1007:13 | Right Power Running Board Motor: Circuit Open | This DTC sets if the RHPRB motor stow or deploy circuit is open when a movement is requested. |
| C1007:19 | Right Power Running Board Motor: Above Threshold | This DTC sets if the RHPRB motor current draw is excessive. |
