DRIVE TRAIN TROUBLESHOOTING (CONTINUED)

FWA (FRONT WHEEL ASSIST) DOES NOT OPERATE

Problem

Solution

FWA switch is ON but bogie wheels do not turn

Check that governor switch is in PAVE, trans. switch is

in LOW & traction lever is pushed FORWARD/
correct positions.

Check manual override on bypass valve.
Check voltage & continuity of bypass valve coil/

Replace coil.

Check voltage & continuity of FWA pump control coil/

Replace coil.

Open electrical circuit

Check for wire off of any terminal in circuit/Reconnect.

Faulty "motion" limit switch (EDC machine only)

Check voltage & continuity/Replace.

Faulty "motion" relay (inside of center console)

Check voltage & continuity/Replace.

Faulty "governor switch" (on center console)

Check voltage & continuity/Replace.

Faulty "trans. switch" (on op. consoles)

Check voltage & continuity/Replace.

Faulty "FWA" switch (on op. consoles)

Check voltage & continuity/Replace.

Inadequate charge pressure

Check at pump/Repair or replace pump.

PARKING BRAKE WILL NOT RELEASE

Problem

Solution

Brake does not release when switch is OFF

Check manual override on control valve.
Check voltage & continuity of control valve coil/

Replace coil.

Clutch is not engaged

Check clutch lever/Engage or adjust.

Air in brake line

Check at caliper bleeder screw/Bleed line.

Leak in brake line

Check hose & fittings/Repair or replace.

Inadequate brake(s) clearance

Check caliper for 0.012 (0.035 mm) running clearance

all around when released/Adjust, repair or
replace.

Open electrical circuit

Check for wire off of any circuit terminal/Reconnect.

Faulty brake switch(es) (on op. console)

Check voltage & continuity at switch/Replace.

Faulty "neutral start" limit switch

Check voltage & continuity/Replace.

(MDC machines only)
