Service and Repair Manual October 2019Control System Fault Codes108 S® -80 XC ™ • S® -85 XC ™ • S®-80 HF • S®-85 HF Part No. 1280490GTID Component ID Name Cause Effect Solution96 Engine OilPressure21 Value toolowThe engine oilpressure ismeasured as toolow, potentiallydamaging theengine.Engine maynot attemptto start untilsystempower cycle.Engine maybe turned offby controlsystemimmediately.* Stop engine as soon as possible.* Verify the engine oil level.* Verify the engine oil pump.* Power on the machine and start theengine. At the ground controls display,view the engine oil pressure gauge forproper operation.* If engine uses an analog oil pressuresensor, verify it is sending an analogvoltage on C25PSR (WH/BK, TCON J6-9).100 PlatformLevel UpValve12 Circuitshorted toV+PCON detectedthat V14PLUcircuit is shortedto 12 V.PlatformLevel Up andpossiblyLevel Downfunctions willnot operate.* With a voltmeter, measure Y20. Properresistance should be between 5 - 60ohms. Replace Y20 if resistance isoutside of those values.* Verify wiring for V14PLU (OR, PCONJ12-6) and check for open or short circuits.15 Circuitshorted toGNDPCON detectedthat V14PLUcircuit is shortedto GND.101 PlatformLevel DownValve12 Circuitshorted toV+PCON detectedthat V15PLDcircuit is shortedto 12 V.PlatformLevel Downand possiblyLevel Upfunctions willnot operate.* With a voltmeter, measure Y19. Properresistance should be between 5 - 60ohms. Replace Y19 if resistance isoutside of those values.* Verify wiring for V15PLD (OR/BK, PCONJ12-7) and check for open or short circuits.15 Circuitshorted toGNDPCON detectedthat V15PLDcircuit is shortedto GND.150 PlatformOverloadRecovery21 ConditionoccurredThis is a flag thatindicates that theplatform wasoverloaded andthat auxiliaryfunction enablewas used whileoverloaded.Advisorycondition.Machine isfullyfunctional.Power up the machine in service modeand clear the flag in the service menu onthe ground control display.152 PrimaryBoomUp/DownFlow Valve12 Circuitshorted toV+TCON detectedthat C3PBF circuitis shorted to 12 V.Boom Upand Downfunctions willnot operate.* With a voltmeter, measure Y12. Properresistance should be between 5 - 60ohms. Replace Y12 if resistance isoutside of those values.* Verify wiring for C3PBF (RD/WH, TCONJ4-4) and check for open or short circuits.* Verify resistance between RecoveryModule pins J37-3 and J37-10 is zeroohms.15 Circuitshorted toGNDTCON detectedthat C3PBF circuitis shorted toGND.
