I need to replace my WYSE 50 terminal with a PC. the connector to the WYSE 50 is a RS-232 25 pin D connector with 3 wires comming out of it (Pin 2,3 and 7) I have a DELL computer with a 9 pin RS-232 connector. I have "Procomm Plus ver 4.6" on the dell and I am thinking I will need to make an adaptor there on one side will be a female db25 to a female db9 ( 2-2 3-3 7-5). I think I may have to jump pin 1 (or 6 or 8) from the db9 side to ground ?

PULL THE WHITE OR CLEAR CONNECTOR AT THE PCM,,,CHECK THE WIRE AT PIN 18 (BLACK WIRE / WHITE STRIPE FOR GROUND.
The following is a summary of the instructions included with the service kit:
1. Remove the negative terminal from the battery.
2. Move the wire located at connector J3 (WHITE/GREY/CLEAR), pin 18 to connector J1 (BLUE), pin 23.
3. Install the jumper wire between connector J2 (RED), pin 26 and connector J3 (WHITE/GREY/CLEAR), pin 18.
4. Install the tag included in the kit around the VCM wiring harness. This tag notes that the wiring harness has been modified.
5. Reconnect the negative battery terminal.

Road test to verify that the condition has been corrected. If any of the following conditions are noted, the transmission should be repaired or replaced using the most cost effective method. Canadian dealers should repair the transmission.
1. Transmission fluid oxidation or excessive sediment.
2. Transmission slip or flare after this service fix is performed.
3. DTC P1870 is stored on a 4L60-E (M30).

The following tools are available from Kent-Moore (1-800-345-2233) for use in removing and relocating the VCM wires:
1. J 41758 Terminal Tool; used to remove the wire from the VCM connector.
2. J 41759 Punch; used to punch a new hole through the connector seal

I believe that's a Speed Sensor issue.

Diag:
1. Ensure mainshaft and countershaft speed sensors are installed properly. Disconnect mainshaft speed sensor harness connector. Using a DVOM, measure resistance between sensor terminals.

2. If resistance is not 400-600 ohms, replace mainshaft speed sensor. If resistance is 400-600 ohms, disconnect 25-pin PCM harness connector "B". Check for continuity between ground and 25-pin PCM harness connector "B", terminals No. 15 (Red wire) and No. 14 (White wire).

3. If continuity is present, repair short to ground in Red or White wire between PCM and mainshaft speed sensor. If continuity is not present, reconnect mainshaft speed sensor harness connector. Measure resistance between 25-pin PCM harness connector "B", terminals No. 15 (Red wire) and No. 14 (White wire).

4. If resistance is not 400-600 ohms, go to next step. If resistance is 400-600 ohms, go to DTC
P0720 (FLASH CODE 9) . Check for loose PCM harness connectors. Replace PCM with a
known-good unit if necessary.

5. Disconnect mainshaft speed sensor harness connector. Check Red wire for continuity between 25-pin PCM harness connector "B", terminal No. 15 and mainshaft speed sensor harness connector. If continuity is present, go to next step. If continuity is not present, repair open in Red wire between 25-pin PCM harness connector and mainshaft speed sensor
harness connector.

6. Check White wire for continuity between 25-pin PCM harness connector "B", terminal No. 14 and mainshaft speed sensor harness connector. If continuity is present, check for loose PCM harness connectors. Replace PCM with a known-good unit if necessary. If continuity is not present, repair open in White wire between 25-pin PCM harness connector and mainshaft speed sensor harness connector.

Speed Sensor probably. Try:
1. Ensure mainshaft and countershaft speed sensors are installed properly. Disconnect mainshaft speed sensor harness connector. Using a DVOM, measure resistance between sensor terminals.

2. If resistance is not 400-600 ohms, replace mainshaft speed sensor. If resistance is 400-600 ohms, disconnect 25-pin PCM harness connector "B". Check for continuity between ground and 25-pin PCM harness connector "B", terminals No. 15 (Red wire) and No. 14 (White wire).

3. If continuity is present, repair short to ground in Red or White wire between PCM and mainshaft speed sensor. If continuity is not present, reconnect mainshaft speed sensor harness connector. Measure resistance between 25-pin PCM harness connector "B", terminals No. 15 (Red wire) and No. 14 (White wire).

4. If resistance is not 400-600 ohms, go to next step. If resistance is 400-600 ohms, go to DTC
P0720 (FLASH CODE 9) . Check for loose PCM harness connectors. Replace PCM with a
known-good unit if necessary.

5. Disconnect mainshaft speed sensor harness connector. Check Red wire for continuity between 25-pin PCM harness connector "B", terminal No. 15 and mainshaft speed sensor harness connector. If continuity is present, go to next step. If continuity is not present, repair open in Red wire between 25-pin PCM harness connector and mainshaft speed sensor
harness connector.

6. Check White wire for continuity between 25-pin PCM harness connector "B", terminal No. 14 and mainshaft speed sensor harness connector. If continuity is present, check for loose PCM harness connectors. Replace PCM with a known-good unit if necessary. If continuity is not present, repair open in White wire between 25-pin PCM harness connector and mainshaft speed sensor harness connector.

on a 99 2.0 model you will have 2 diagnostic ports. both of them will be the fiat 3 pin type.

to connect the 3 pin fiat connector to a 16 pin obd2 connector you need 4 lengths of wire. use 3 lengths of wire to connect the 3 pin connector to the obd connector. also use 1 length of wire for power to the obd connector.

on the 16 pin obd2 connector use the following pins
4- chassis ground (connect to ground on 3 pin connector, or any good chassis earth)
5- signal ground (connect to black wire pin on 3 pin connector)
7- k line (connect to white wire pin on 3 pin connector)
16- 12vDC (connect to battery positive terminal)

DTC P1705 - NC2 (Direct Clutch Speed Sensor) Revolution Sensor Circuit malfunction or Direct Clutch Speed Sensor Output is 300 RPM or less with Vehicle at 20 MPH or more & with Park/Neutral Position Switch Off

Most probably you have an electrical fault causing the problem and attached is a diagnostic procedure. It could be 2 separate problems and after rectifying the P1705 only would you know it is single or 2. Repair manual shows right on top of transmission, black sensor with single bolt, 2 wire plug. P/N 89413-08020 list price $113.80

NOTE: DTC P1705 is set when PCM receives 2 gear position signals at the same time.

1. Turn ignition on. If any A/T gear position indicator lights remain illuminated when gear selector is moved from that gear, go to next step. If all A/T gear position indicator lights turn off when gear selector is moved from that gear, system is okay at this time.

2. Disconnect A/T gear position switch connector. If all A/T gear position switch indicators go out, replace A/T gear position switch. If all A/T gear position switch indicators do not go out, go to next step.

3. Reconnect A/T gear position switch connector. Shift through all gear positions except Reverse. Using a DVOM, measure voltage between 16-pin PCM harness connector "D", terminal No. 6 (Green/Red wire on 2.3CL or White wire on Accord and Odyssey) and 25-pin PCM harness connector "B" terminals No. 20 or 22 (Brown/Black wires).

If battery voltage is present, go to next step. If battery voltage is not present, check for a short in Green/Red or White wire between 16-pin PCM harness connector "D" and A/T gear position indicator, or A/T gear position switch. Repair as necessary. If Green/Red or White wire is okay, check for loose PCM harness connectors. Replace PCM with a known-good unit if necessary.

4. Shift through all gear positions except Neutral and Park. Measure voltage between 16-pin PCM harness connector "D", terminal No. 13 (Blue/White wire on Accord or Light Green wire on 2.3CL and Odyssey) and 25-pin PCM harness connector "B" terminals No. 20 or 22 (Brown/Black wires). If battery voltage is present, go to next step. If battery voltage is not present, check for a short in Blue/White or Light Green wire between 16-pin PCM harness connector "D" and A/T gear position indicator, or A/T gear position switch. Repair as necessary. If Blue/White or Light Green wire is okay, check for loose PCM harness connectors. Replace PCM with a known-good unit if necessary.

5. Shift through all gear positions except "D4". Measure voltage between 16-pin PCM harness connector "D", terminal No. 9 (Light Green/Black wire on 2.3CL or Yellow wire on Accord and Odyssey) and 25-pin PCM harness connector "B" terminals No. 20 or 22 (Brown/Black wires). If battery voltage is present, go to next step. If battery voltage is not present, check for a short in Light Green/Black or Yellow wire between 16-pin PCM harness connector "D" and A/T gear position switch. Repair as necessary. If Light Green/Black or Yellow wire is okay, check for loose PCM harness connectors. Replace PCM with a known-good unit if necessary.

6. Shift through all gear positions except "D3".

Hello,

Wyse 50/60/150/160 monitors were my specialty!

From what you were explaining it seems to me that you have a bad internal battery and it needs to be changed and a factory reset/ calibration needs to be performed.

I can repair wyse terminals at my facility if you like. The repair cost is not that high and we can also perform the regular repair and adjustments on all wyse monitors if needed.

Please contact me if you have any questions.

Thanks

Serial meaning 2.5mm stereo headphone looking jack to DB9 or "atari joystick" looking plug? I had one on my first Toshiba PDR-M1 camera but that was like 9 years ago. You can probably find the pinouts online for that cable, I believe it is a standardized cable.

The stereo plug is wired to the PC serial port as shown in the following diagram:
tip ring sleeve +---------------------------------+
| |
/-------+-----+--------------+ |
| RxD | Gnd | TxD | 2.5 mm Stero Plug |
\-------+-----+--------------+ |
| |
DB9*: pin 2 pin 5 pin 3 +---------------------------------+

DB9*: Optionally short together pin 4 (DTR) to pin 6 (DSR) and
pin 7 (RTS) to pin 8 (CTS)
The following table also describes the camera cable's wiring: Camera PC's
Plug DB9* Signal Name Direction
---- ---- ----------- ---------
- 1 Carrier detect (CD) input to PC
tip 2 Receive data (RxD) input to PC
sleeve 3 Transmit data (TxD) output from PC
- 4 \ Data terminal ready (DTR) output from PC
ring 5 | Signal ground (Gnd) -
- 6 / Data set ready (DSR) input to PC
- 7 \ Request to send (RTS) output from PC
- 8 / Clear to send (CTS) input to PC
- 9 Ring indicator (RI) input to PC
* Note that the cable's D-subminature DB9 RS-232 serial port connector is female. This connector also goes by the historically more correct name of "DE-9J".

The Pin Assignment is as follows:
Pin 1,4: +5V
Pin 2,3: not connected
Shield: Ground
The AC Adaptor is specified as 5V , 4Ampere. Actually the unit draws around 2-3 Amperes.

This "Image" shows the pins, when you look onto the jack at the back side of the terminal, with the terminal standing upright. The label = 5V is located left of the jack
