How to jump the SCS line with the HDS?

How to jump the SCS line with the HDS?

To prevent this they tell you to jump the SCS line with the HDS. This is done after you turn the key to the LOCK (0) position. They instruct you to use the HDS to jump the SCS line and then remove your PCM connectors and do your testing. Once you’re done, you reconnect the PCM and then un-jump the SCS.

What is SCS on a Honda?

The Honda Service Check Short Service connector is a simple jumper connector that is used to check and erase Diagnostic Trouble Codes (DTC). This SCS service connector is needed on a wide range of Honda powersport engines- ATVs, motorcycles, and personal watercraft all require this basic tool.

What is SCS circuit?

A silicon-controlled switch, or SCS, is essentially an SCR with an extra gate terminal. Typically, the load current through an SCS is carried by the anode gate and cathode terminals, with the cathode gate and anode terminals sufficing as control leads.

What is SCS thyristor?

Silicon controlled switch (SCS), like the SCR, is a unilateral, four layer three junction P-N-P-N silicon device with four electrodes namely cathode C, cathode gate Gx, anode gate G2 and the anode A, as shown in figure. Infact, the SCS is a low power device compared with the SCR.

How many terminals are in a silicon control switch?

3 terminals
Background: A silicon controlled rectifier (SCR) is a four-layer solid state current controlling device with 3 terminals. They have anode and cathode terminals like a conventional diode and a third control terminal, referred to as the Gate.

What is HDS tool?

What is an HDS tool? HDS stands for Honda Diagnostic System and is the software that Honda uses for diagnosing/managing higher level engine components and systems such as fuel, SRS, CKP, etc. Traditionally OBDII scanners do not allow this level of functionality.

What is the advantage of SCS?

An advantage of SCS over an SCR is the reduced turn-off time, typically within the range of 1 to 10 micro seconds for the SCS and 5 to 30 micro seconds for the SCR. Other advantages of the SCS over SCR are increased control and triggering sensitivity and a more predictable firing situation.

What is the difference between SCS and SCR?

One of the crucial difference between diode and thyristor is that a diode is a two terminal device used for rectification and switching applications….Comparison Chart.

Basis for Comparison Diode Thyristor (SCR)
Number of layers 2 4
Number of junctions 1 3
Number of terminals 2 (Anode and Cathode) 3 (Anode, Cathode and Gate)

What are the three terminals of SCR?

Background: A silicon controlled rectifier (SCR) is a four-layer solid state current controlling device with 3 terminals. They have anode and cathode terminals like a conventional diode and a third control terminal, referred to as the Gate.

How many terminals does a SCS device have?

Exercise :: PNPN – General Questions 27. How many terminals does a silicon-controlled switch (SCS) device have? 28.

What does the pilot chute pull out of the parachute?

The pilot chute catches the air and inflates. It pulls out a 7 to 10-foot long (2 to 3-meter) piece of nylon webbing called the bridle. As the bridle is coming out of the container, it pulls a pin, called the closing pin, on the container. This pin holds the main canopy inside the container.

How to disconnect SCS service connector from MES connector?

5th Disconnect SCS service connector from MES connector within 4 seconds. SRS indicator light will indicate that memory is erased by blinking 2 times. 6th Turn ignition off, and wait 10 seconds.

How does the SCS service connector and SRS reset?

Here’s a diagram for clearer understanding. 1st step in erasing the memory is to turn the ignition off and connect the SCS Service connector to the MES Plug, 2nd Turn Ignition on. SRS indicator light will come on for about 6 seconds then go off.

What’s the model number of a Honda SCS service connector?

The Metra model number is 72-7802. Cut the female disconnects off the ends of the speaker harnesses and strip about a half inch of jacket off of the wire. Twist the wire together and tape up the bare wire, you now have an SCS Service Connector for quite a but less than what Honda would have charged for one.

Can you jump the SCS line with the HDS?

The HDS grounds the SCS line internally through the DLC. Honda does not want people to use jumper wires or probes because of the connector pins being damaged. Honda SCS line should be pin 9 in the DLC. Improvise.

What should the bottom of the SCS connector look like?

Seems to show the connector a little clearer. Brown wire on bottom and black in middle (adjacent to brown/black wire). Turn key to “on” position and start counting. Be ready, have a pen and paper ready or–better yet–just record it on your phone for future reference.

What happens when you ground the SCS line?

What they are telling you is essentially to ground the SCS line to the PCM. That puts the system in Test Mode so that when you start the engine and hold the engine speed up to run the test for the knock sensor circuit the system knows it is in test mode.
