Apple Hardware Reference Code Ppf004 Replace the Fan
Economic consumption SMC Sensor Codes to interpret Apple Software package Diagnostics(ASD) output. ASD is free only as a bootable DMG images which should be burned on
Apple Diagnostics(AD) replaces intrinsic Apple Hardware Test(AHT) for devices manufactured after 2013. Some older devices will too load AD instead of AHT if you update the OS or expend Option+D to download it online. Many older devices lose AHT after upgrading your OS, since information technology wipes it from the hard drive and its not available online.
AHT Codes are more complex and give more information happening the egress.
The first region is a twist name:
- 4ETH: Ethernet controller
- 4IRP: Independent Logic board
- 4MLB: Logic circuit board controller
- 4PRC: Processor
- 4HDD: Hard saucer
- 4MHD: External disk
- 4YDC: Telecasting card
- 4SNS: Scheme sensor
- 4MOT: Fan motor
- 4MEM: Memory faculty
- 4AIR: AirPort wireless card
Most of them pretty straight-forward except 4SNS which will be follower by either V (Voltage or Current sensor) or T for thermal sensor.
- A: Ambient Air Sensor
- B: Electric battery
- C: Nuclear Processors (CPU)
- D: Direct current (Direct Ongoing)
- e: PCI-Verbalize Slot
- F: FireWire Port
- G: Graphics Processor (GPU)
- H: Hard Disk
- h: Estrus Sink (or Heat Pipe)
- L: LCD display
- M: Store (or Memory Riser Boards)
- m: Miscellaneous (Peripherals such Eastern Samoa a Battery Charger)
- N: North Nosepiece (System of logic Board Controller)
- O: Optical Drives
- P: Power Bus
- p: Baron Supply
- s: Trackpad
- W: Airport Wisconsin-Fi Identity card
For model: 4SNS/1/40000000: TA00 means Close thermal sensor.
If your twist is newer than 2013 or you booting it online from close to older devices, there's Advertizing which is much fewer reliable and kind of helps you to Good Book an appointment in Genius Bar instead of showing the realistic issue. Wont Apple MRI to gather more info.
