Question about Sony SA-WX700 Subwoofer

Open Question

Initial problem C860 low and R830 burnt and 1/2 value. Replaced but now after initial turn on (about 15 secs) low pulse output. +12V rail is pulsing and low.

My 2001 park ave just killed on me wont start


Make sure battery has a full charge and battery connections all good. If it cranks good but won't start, have a helper crank it while you visually check for spark at the plugs. If spark everywhere, use a gage and check proper fuel pressure. Also, check fuel injector pulse. Having fuel in the fuel rail is good as far as it goes. You don't need rpm signal for initial prime.
Any applicable trouble codes?

WHAT IS THE MEANING OF FAULT CODE 21,24 AND 31


21 - VANOS solenoid activation, intake Output digital pulse width (active low)
DME final stage will set flag
whenever a short to ground, a short
to battery voltage or a disconnection
between output transistor and
component exists.

24 - Injector circuit cyl. 4 Output digital pulse width (active low)
DME final stage will set flag
whenever a short to ground, a short
to battery voltage or a disconnection
between output transistor and
component exists.

31 - Ignition coil cyl.5 Input analog timing
DME initiates secondary ignition for
(100 mV) each cylinder then looks for feedback
through shunt resistor in harness to
determine if ignition actually occurred.

The settings for welding aluminium using a Tig200P AC/DC inverter


If you are using a remote then you would set the machine in standard for controlling output and also to AC output, HF tig, contactor and control in remote position. I don't know if this helps or not but I pulled it from an owners manual.


1/16" (.062) - pre-flow .1 sec., hot start 20, amperage 70, Hz 100, balance 20%, post-flow 6.0 sec.

For pulse settings - set pulse width 60%, peak current 100, background current 30, Hz 1.0

1/8" (.125) - pre-flow .1 sec., hot start 20, amperage 150, Hz 80, balance 20%, post-flow 6.0 sec.

For pulse settings - set pulse width 60%, peak current 150, background current 50, Hz 1.0

3/16"-1/4" - pre-flow .1 sec., hot start 20, amperage 185, Hz 60, balance 20%, post-flow 8.0 sec.
For pulse settings - set pulse width 60%, peak current 185, Background current 125, Hz 1.0

The pulse reading often displays a low value like 60 even though my pulse is 120 or higher.


Good contact with the grip is essential. Before taking pulse, stop walking and step on side rails and place hands on contacts.

Try gripping the handlebar contacts over the top, with your thumb next to your index finger instead of gripping it with your thumb under the handlebars.
Contact heart rate grips are not intended for continuous reading. Rather, try holding the grips for 10-20 seconds at a time for an accurate reading.
Static electricity can damage the heart rate grip receiver and/or grips and cause either an "HR" or no reading at all.

I Have A 2000 Hyundai Accent And The Codes P1529 and P0722 Came Up. What Does This Mean. Please Help Me Out.


P1529 - MIL light request

P0722 - Transmission Pulse Generator B. The Pulse Generator detects the revolution of the idler gear parking pawl lock gear and emits a pulse signal. The pulse signal is sent to the Transmission Control Module (TCM) which converts it into vehicle speed. The code is detected when the Pulse Generator B failed to provide a signal to the TCM upon initial movement of vehicle.

Symptoms:
- Engine Light On (or Service Engine Soon Warning Light)
- Speedometer improper reading
- Possible shifting problems

Possible Causes:
- Pulse Generator B harness or connectors
- Pulse Generator B circuit is open or shorted
- Pulse Generator B

Code 19


6X Signal Fault The 6X output signal is a five volt square wave that is initially high. The signal switches low at each of the six. 60 degrees crankshaft position (CKP) sensor pulses. The 6X signal is used by the PCM for greater rpm resolution and in determining KS circuit (system) (knock ******) windowing. Diagnostic Trouble Code parameters: DTC 19 will set if: Three 6X pulses do not occur between each reference pulse. A 6X pulse does not immediately follow a reference pulse

Problem is most likely the crankshaft position sensor or the ignition module.

Pioneer bus cable wiring


You asked for it...
..it's a little complicated.

The pioneer IP bus uses a 2 wire differential signal for communication.
An equal level on both lines is a logical low while a high is encoded as a voltage difference of some 100mV.
I think a CANbus tranceiver should work here.
The data transfer is initiated by either the cd changer or the radio.The initiator generates a high pulse ( ca. 170us ) and a following low pulse ( ca 20us ).
Then the data transfer starts, a 1 is encoded as a high-low sequence with a duration of ap. 20us for both levels and a 0 consists of a 33us high and a 7us low pulse.
The data is now transfered in bytes with MSB first, the 8th bit is an odd parity bit.At the end of the 3rd and all following Bytes there is an additional bit inserted after the parity where the receiver acknowledges the transfer.
This is done by holding the data lines in a high state after the initiator sets them low.If this ack is missing the transfer is stopped.
The timings may vary because the real data is encoded in the pulse to space length relation.
The first 3Bytes seem to be some kind of device address.The changer I used transfered a 0x88,0x68,0x00 here while the radio sended 0x88,0x08,0x06.
The next 4 bits were always high. After that a size byte and then size bytes were transfered. The last byte in the transfer is a checksum generated adding the values of all data beginning with the 4bit sequence ( = 0x0F ).
In the following part I only will write the raw data excluding size and cheksum field.
Each command transfered was first answered by some acknowledge packet consisting of a single 0xA1.
(which looks like: 0x88 0x08 0x06 0xF 0x02 0xA1 0xB2 -> 0xB0 is the checksum ).
For now I just figured out some very basic things like the fields where time, track and disc number are encoded and also some
key codes the radio sends. There are many more fields in the packets where i still don't know the meaning of.
(I just got the radio from a friend for some days and so I couldn't do so much more on it ... however .. if somebody is intrested in some
more information and is wiling giving me a radio and a changer for some weeks I'll try to do some more .... )
I have also designed a small circuit using a AT90S2313 controller which can be used for logging the transfer through the pc serial port and also
to send commands.
The following packet sended by the changer contained the time disc and track information.
Byte 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 Info command modus mcd disc min sec track cdt Data 0x61 0x10 0x06 0x01 0x20 0x04 0x16 0x01 0x06 0x01 0x00 0x00 0x01 0x00 0x3F 0x00 0x00 0x00 0xC0 0x48 modus:
Value 0x02 0x07 0x08 0x10 0x11 0x13 0x14 0x15 0x16 Info ready track blink pause ready and disc blink disc blink load and disc blink eject and disc blink load eject cdt: bit0: (1:cdtext),(0:normal)
The text information was encoded within this packet
Byte 0 1 2 3 4 5 6 7 8 9 10 11 12 13-22 Info command modus disc track text seqence number text Data 0x61 0x10 0x06 0x01 0x20 0x04 0x38 0x09 0x00 0x06 0x00 0x00 0x00 0x00
