PINPOINT TEST U: THE LH/RH TURN OR HIGH BEAM INDICATOR IS NEVER/ALWAYS ON

Normal Operation
When the multifunction switch is in the LH or RH TURN position or if the high beams are on, a message is sent to the instrument cluster from the SJB over the medium speed controller area network (CAN) communication bus. The instrument cluster upon receipt of the LH/RH turn or high beam on message, flashes the LH or RH turn signal indicator on and off or illuminates the high beam indicator.
