Penyebab parking brake di volvo fm 400 versi 4.parking brake tidak mau aktif apa pak? Jadi di port 28 dan 29.2 di APM keluar angin terus.kira2 komponen d APM apa yg menyebabkan itu?
Apakah switch parking brake nya menyala saat di parking? Kondisi release 28.1 dan 28.2 itu selalu ada angin, sedangkan 29.2 itu juga selalu ada angin, sedangkan saat parking, angin tidak ada diposisi tersebut
@@chrisnsangarasi9440 alhamdulillah sudah ketemu pak.. Sampek mumet trnyata ada yg lupa dpasang spring yg di PCV dekat protection valve nya.yg bongkar konco jdi gak copy 😁 Awalnya error actuator stuck open pak 😄
dan kabel yang saya perbaiki adalah kabel warna biru dan putih yang terdapat pada konektor/solenoid abs yang berada pada bagian belakang sebelah kanan pada output valve.
Only c107473= actuator stuck closed, wheel 1 rpm pressure control. Rootcause damage piping or part between rpm and wheel brake,damage piping or part between rpm and supply pressure, received supply pressure value from apm incorrect,rpm damage
1. Trailer control module or its pipe connection is damaged or incorrect trailer control port is not plugged 2. Trailer control module supply line is damaged. 3. Spring brake lines are damaged. 4. Parking brake relay valve failure 5. Sensor failure 6. APM internal valve failure
TCM: disconnect the TCM pipe on APM port - close it's port with plug. check park brake application and release 5 times. if it's working failure free, replace TCM.- Exhaust: check Park brake relay valve silencers for blocking and dirt, check the plastic cover (plastic part can be removed for the check and put back after) of the secondary exhausts on the bottom against dirt and blocking.- Relay valve: exchange relay valve if other actions are not effective.
C10022F=Large airgap, dirty tone wheel, missing or destroyed tone wheel teeth, toggling tone wheel, production-failures of tone wheel, damaged wheel speed sensor, wheel speed sensor mounting. Action="Check the tone wheel for dirt and metallic particles, for wobble, for pitch error, for the correct number of teeth.Check wheel speed sensor mounting (Check ""Klämhylsa"").Check the cables and connectors between ECU and wheel-speed sensor for short-circuits and open-circuits.Measure resistance of Sensor and cabling. Resistance must be between 800 ... 2000 Ohm.Measure insulation resistance of sensor and cabling to vehicle GND. Resistance must be > 200kOhm.Do waveform check with oscilloscope. Check and correct air gap between wheel speed sensor and tone wheel by measuring the wheel speed signal. (Wheel speed sensor signal must be higher than 100mV peak to peak at wheel speed of about 3-5km/h). U300049=Too high battery voltage or damage of the vehicle's power supply system or damage in the wiring or connectors for the ECU supply or damage in the wiring or damaged dataset or damaged software or damaged ECU Action= Replace ECU U114286=Signal invalid, Wheel-Based Vehicle Speed
