Troubleshooting SID 232, FMI 0, Flash Code 75, Sensor Supply Voltage High

Troubleshoot as follows:‪

NOTICE:

To avoid damage to the harness and connectors when disconnecting harness connectors, ensure the pulling force is applied to the connectors and not to the wires extending from the connectors.‪

  1. Check wire 916 (red and black, 5 VDC sensor supply) for a short to battery (+12/24 VDC) at cavity A-3 in the Vehicle Interface Harness (VIH) 30–pin connector (see Figure "Vehicle Interface Harness 30–pin Connector" ). If there is a short, repair or replace the wire, pins, and sockets.
