Test E: DTC B1162, B1163, B1164 Or B1170 - The Power Running Board (PRB) Does Not Operate Correctly

PINPOINT TEST E: DTC B1162, B1163, B1164 OR B1170 - THE POWER RUNNING BOARD (PRB) DOES NOT OPERATE CORRECTLY

Normal Operation
The power running board (PRB) module provides a regulated 10-volt power supply to the Hall-effect sensor (internal to the PRB motor) through circuit CPR47 (GY/BN). The Hall-effect ground is provided by the PRB module through circuit RPR47 (BU/GN). The PRB module monitors the PRB Hall-effect signal through circuit VPR43 (GY/BU) (LH) or VPR46 (GY/OG) (RH). If the PRB module does not receive any signal from the Hall-effect sensor during operation, the PRB will stop.







This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- PRB module
- LH or RH PRB motor assembly
