Welcome to the Forums Mario!

The wrenches on the Forum will need the serial # of the machine in order to help you out.

Good luck!

Excellent. Makes it ewasier to find info.
See attached. The Code is for the service brake pedal switch. This is the switch that dumps pressure in the parking/secondary brake system and applies the PB when the pedal is pressed all the way down to the floor.

113.298.02
Transmission control: service brake pedal switch; erratic intermittent or incorrect.

Most of the time, the brake pedal switch needs adjustment to prevent this code from coming on.

Perfect. Thank you guys.

Not sure if this is against the rules. Is it okay to request digital service manuals?

If the abbreviated schematic included in the troubleshooting procedure is a bit short on detail you can have a complete electrical schematic for the whole machine. Just ask.

Could I have the complete electrical schematic please?

No it's not. You need to be on the lookout for the following Cat Publications in the usual online marketplaces. Figures in brackets are approx new prices.

SEBU6887-06 - Operation & Maintenance Manual ($50)
SEBP2619-24 - Parts Manual ($125)
SENR9490 - Service Manual - will include an O&M Manual if complete. ($395)

Could I have the complete electrical schematic please?

Check your messages.

If you go in messing with the switch - be careful. With the machine master switch in the ON position one of the wires connected to the switch is permanently live. Get your terminal screwdriver at the wrong angle and there could be quite a flash......

It might be worth saying the 1 part of the brake system works on PWM at 5 volts the peddle limit switch works on 24 volt the same as the hand button control (park)

Hey guys. How do I enter Component Data Display Mode to check the operation of the switch?

You don't really need to. Just get at the switch behind the cover above the brake pedal, unplug CONN 19 (198-RD and G731-GY) then test the continuity of the switch. It should be open circuit until the brake pedal is almost at the floor when the contacts should close.

From memory the red & grey wires attach at the switch with screws, so you could also disconnect at that location.
