Base Section 5 – Procedures
Pin 11 - Enable out- Negative output on wire 208 to relays 208CR and 208CR1.
Test for negative at pin 11 while operating from base or upper controls.
Pin 12 - Enable in- 12 volt input on wire 8B from footswitch S6 or base enable switch S21.
Test between pin 12 and battery negative while activating footswitch or base enable switch.
Pin 13 - 12 volt input on wire 24 from left steer switch.
Test between pin 13 and battery negative while operating left steer.
Pin 14 - 12 volt input on wire 23 from right steer switch.
Test between pin 14 and battery negative while operating right steer.
Pin 15 - Negative output on wire 224 to left steer valve 4H-224.
Test pin 15 for negative while operating left steer. (Platform must be over drive axle)
Pin 16 - Negative output on wire 223 to right steer valve 4H-223.
Test pin 16 for negative while operating right steer. (Platform must be over drive axle)
Pin 17 - Variable negative output on wire 90 to battery condition light PL4.
(No light= Charged… Solid light= Warning… Blinking light= Limp mode)
Test for negative at pin 17.
Pin 18 - 12 volt input from platform Load cell on wire 162.
12 volts= within platform capacity. 0 volts= overload.
Test for continuity between pin 18 and battery negative while no load in platform. Refer to Load Sense
troubleshooting in section 5 for additional information.
Pin 19 - PMU accelerator input. Variable input from wire 70. 10-100% of maximum pump speed. (PWM signal)
Test for varied input at pin 19 while operating from upper controls.
Pin 20 - Base speed 1 input on wire 71. 70% of pump speed.
Test continuity on wire 71 between pin 20 and base terminal block.
Pin 21 - Base speed 2 input on wire 72. 50% of pump speed.
Test continuity on wire 72 between pin 21 and base terminal block.
Pin 22 - Base speed 3 input on wire 73. 8% of pump speed.
Test continuity on wire 73 between pin 22 and base terminal block.
