DTC Descriptor
DTC B3875 00
- Wiper High Speed Relay Circuit
Diagnostic Fault Information
Circuit/System Description
The body control module (BCM) monitors the wiper high speed relay control circuit only when wiper high speed mode is active. When the wiper
high speed mode is requested, the BCM responds by applying a ground through the wiper high speed relay control circuit to the coil side of the
relay, energizing the WPR HI Relay.
Conditions for Running the DTC
This DTC can set only when the output is actively being requested by the BCM.
Conditions for Setting the DTC
This DTC sets if the BCM detects a short to voltage on the WIPER 2 relay control circuit.
Action Taken When the DTC Sets
The BCM will not activate the output.
Conditions for Clearing the DTC
