Have you received a Bobcat S185 Trouble Code or Error Code? Here is a list of all the bobcat S185 error codes made by Bobcat. Codes 1-15 represent a sensor on your machine, and codes 16-99 are engine or drivetrain codes. Find the source of the problem by matching your trouble code/error code to one in this article.
1-6 1618 Fuel pump low pressure
Turn the ignition key to OFF before proceeding.
Connect a fuel pressure gauge to the fuel system test port. The engine must be OFF for an accurate pressure reading.
Start the engine and let it idle for three minutes. Record the fuel pressure reading. If the fuel pressure is not within specification, follow the appropriate procedure below to diagnose the problem:
If the engine will not start or run, refer to Engine cranks but does not start in Engine Performance Diagnosis for diagnosis procedures.
Si machina incipiet et currat, refer ad Driveability Symptomata Chart in Driveability Diagnosis pro diagnosi procedendi.
1-7 1619 Engine coolant temperature sensor high input
Causis fieri
Engine coolant temperies (ECT) sensorem phaleras vel connexiones aperta vel shorted
ECT sensorem circa pauperem nexum electricam
Vitiosa ECT sensorem
Vitiosa engine imperium moduli (ECM)
1-8 1620 Engine coolant temperature sensor low input
1-8 1620 Engine coolant temperamentum sensorem low input.
Machinam coolant temperaturae signum sensoris infra valorem referentem est.
1) Aperi vel breve in phaleras vel iungo inter PCM et machinam sensorem (ECT) sensorem (ECT signum circuii).
2) ECT sensor ambitus apertus, brevis ad terram, seu brevis ad potentiam.
3) PCM defectum.
2-4 3572 Engine coolant level switch – short to ground
Machinam coolant in plano switch sita in subsidiis piscinam et cum contactu interno instructum est. Hoc contactum monitores ECM mittit et signum botri instrumenti mittit ut in humilitatem coolant indicatorum. Brevis ad terram in machinam coolant in plano switch hoc DTC ad occasum facit.
2-5 3573 Engine coolant level switch – short to voltage
Troubleshooting dux pro defectu codicis 2-5, machinam coolant level switch – breve ad voltage.
Hoc codice defectus per "CHECKMUM ANGI" indicator lucerna indicata est. The Engine Control Module (ECM) illuminabit "CHECK ENGINEM" indicator lucerna statim in hac defectione detecta. Si haec culpa non reparatur, ECM ulterius agere potest, pro condicionibus operantibus.
3-2 5067 Main relief valve solenoid open/short to voltage
The main relief valve solenoid circuit is monitored by the transmission control module (TCM) for a short to voltage. The test fails when the main relief valve solenoid is commanded to ON, and the TCM detects a voltage greater than 4.5 volts on the main relief valve solenoid control circuit for approximately 1 second or more.
Conditions for Running the DTC
The ignition switch is in RUN or START.
The ECT sensor input varies less than approximately 6 C/11 F (or 3 C/6 F) from stored values.
The engine speed is more than 550 RPM.
Conditiones constituendi DTC
The TCM detects a voltage greater than 4.5 volts on the main relief valve solenoid control circuit for approximately 1 second or more while commanding the main relief valve solenoid ON.
Actio, cum DTC Sets
TCM indicator lucernam malfunction (MIL) illuminat cum diagnostica fugit et deficit.
3-3 5068 Main relief valve solenoid short to ground
The 3-3 5068 Valvae solenoidalis brevis ad terram subsidio principale est error codicis qui solum in Systemate Extrema Series hydraulica monstrabit. Summa valvae solenoidis subsidio est orificium variabile, quod moderatur quantum pressura hydraulica per eam transire permittitur. Cum in solenoideis nulla est potestas, ad locum plane apertum defaltam. Interdum ut "valvae subsidii pressurae" vel "relevatio principalis" valvae refertur, haec valvula agit ut machinam tutam, limitando quantitatem pressionis quae in systemate applicari potest.
3-4 5069 Lift relief valve solenoid open/short to voltage
Make sure the lift relief valve is not plugged up. If a new valve did not correct the problem, then you will have to check the solenoid and make sure it is working properly.
You will need to check the voltage going to the lift relief valve solenoid, which should be battery voltage. If there is no power going to the solenoid, check the wiring and fuses.
If there is power going to the lift relief valve solenoid, test the continuity of the coil on the solenoid. You should have zero ohms of resistance on a good coil. If you don’t have any resistance, replace the lift relief valve coil.
5-4 7074 Engine speed sensor signal is too low or absent
Test system operation by performing a quick check.
Si quis indicibus malfunction emissivus est, systema indicatur inspice. Refer ad ministerium manuale pro diagnosi et reparatione congruenti systematis.
Reprehendo machinam celeritatem sensorem phaleras connexiones solutas, ruptas, terminales laedi.
Reprehendo pro solutam vel absentis engine celeritatem sensorem fulmina escendens.
Reprehendo pro terra propria ad celeritatem sensorem phaleris machinae iungo. Ambitus debet habere minus quam 1 olim ad terram resistendi. Si major quam 1 olim resistendi ad terram inveniatur, reparatione ut necessaria est. Si omnes ambitus OK reprehendo, repone ECM/PCM.
