S6 open: >4.0V; S6 closed: <0.5V S6 VM TILT_DOWN Input to the VM from the Tilt Down button (S7). S7 open: >4.0V; S7 closed: <0.5V S7 VM H_HTR DC supply to optional handle heater (HTR6). OFF: <0.5V; ON: 7.5 to 8.5V VM Control Handle SSHIFT_LEFT Input to the VM from the Sideshift Left button (S8). S8 open: >4.0V; S8 closed: <0.5V S8 VM SSHIFT_RIGHT Input to the VM from the Sideshift Right button (S9). S9 open: >4.0V; S9 closed: <0.5V S9 VM S3 open: >4.0V; S3 closed: <0.5V S3 VM Theory of Operations Signal User 24 JPC12-10 P_HORN Input to the VM from the Control Handle Horn Switch (S3). Note: When other aux function switches are activated, reading can change by as much as 0.5V. 25 JPC12-11 RETRACT Input to the VM from the Retract Switch (S5). Note: When other aux function switches are activated, reading can change by as much as 0.5V. S5 open: >4.0V; S5 closed: <0.5V S5 VM <0.5V; B+ wrt TP1 VM Control Handle 26 JPC12-12 DGND Reference for all switches and potentiometers in the Control Handle. If this voltage is not <0.5V wrt TP4 on the power panel, then intermittent handle codes may appear. 27 JPC14-1 B–F This connects B–F on the VM to TP4 (B–) <0.5V wrt TP4 through FU6 on the Fuse/Relay Card (FRC). FRC VM DGND This connects DGND and AGND on the VM to TP4 (B–) through FU6 on the Fuse/Relay Card. This is the reference for all circuits on the truck that are referenced to either DGND or AGND.
