California Code of Regulations (CC&R)

3340.41(d) – The specifications and procedures required by Section 44016 of the Health and Safety Code shall be the vehicle manufacturers recommended procedures for emission problem diagnosis and repair or the emission diagnosis and repair procedures found in industry-standard reference manuals and periodicals published by nationally recognized repair information providers. Smog check stations and smog check technicians shall, at a minimum, follow the applicable specifications and procedures when diagnosing defects or performing repairs for vehicles that fail a smog check test.

Fuel Costs

Most Smog Check failure repairs will positively influence a vehicle’s fuel economy, performance and durability

did you know
Did You Know?

California’s current vehicle-dependent lifestyle has led to a dramatic increase in health risks

California has more registered cars than any other state

95 percent of all Californians breathe in dangerous levels of smog on a regular basis

Every year, more people die from air quality-related health issues than car accidents

did you know1
Did You Know?

California’s current vehicle-dependent lifestyle has led to a dramatic increase in health risks

50 percent of all California’s motor vehicle pollution is produced by only 10 - 15 percent of the state’s total number of cars driven

A poorly maintained or malfunctioning vehicle can release as much as 10 times the emissions of a well maintained vehicle

We will be using these Critical Thinking Skills along with the datasheets on the 3 Case Scenariosduring the lab session
using the internet
USING THE INTERNET

In recent years, legislation was passed requiring all vehicle manufacturers (mfgs.) to provide aftermarket repair technicians and shops with all the information needed to diagnose and repair their vehicles.

Mfgs. were required to make this information available, via the internet, to aftermarket technicians at a nominal fee.

Unfortunately, these mfg. websites are being under used by many technicians and shops!

using the internet1
USING THE INTERNET

To successfully diagnose and repair today’s high tech vehicles,

YOU NEED TO USE THE INTERNET!!

The following slides go over some internet basics as they pertain to smog inspections, vehicle diagnosis, and repairs.

For some, this lesson will seem very basic and we ask for your indulgence.

For others, it will open up new avenues for inspection, diagnostic, and repair information.

using the internet getting on the internet
USING THE INTERNET – Getting on the Internet

Q: OK, so how do you get on the internet?

A: To access the internet, you need:

  • A computer linked to the internet through a internet service provider.
  • Your personal computer (PC) needs a program called an internet browser. Among the common browser programs are: “Internet Explorer”, “Safari” (Apple PCs), “Mozilla”, “Opera”, etc. Your PC probably has one of these programs already installed on it’s hard drive.
using the internet getting on the internet1
USING THE INTERNET – Getting on the Internet

Q: The student course syllabus says that I must do an internet homework assignment to pass the course; if I don’t own a PC how can I complete this assignment?

A: The following options are available:

  • Most public libraries have PCs that you may use for free! you just need to get a library card. They also have staff that can assist you.
  • Find an “internet cafe” and pay a small fee to use their PCs.
  • Ask your employer or a friend if they would allow you to use their PC.
using the internet website addresses
USING THE INTERNET – Website Addresses

You have seen it a million times on TV. The announcer says “For more information go to our website”; then you see this funny sentence at the bottom of the screen that starts off with a “www.” and ends with a “.com” and a strange name in between – what does that mean?

When a company wants to be on the internet they are given a specific address called their website address (home page). This address usually starts with a www. (meaning world wide web), a name, then “.com” (for “commercial”). If the group is not a commercial enterprise (like a charity), it could end in “.org” (for “organization”), “.edu” (for education), or “.gov” (for “government”).

using the internet website addresses1
USING THE INTERNET – Website Addresses

To access a specific website, you need to enter the correct address in the browser’s address box.

When you enter this address, you must enter the address characters exactly as you see it – no spaces, and type all the characters (e.g. @, -, /, _ etc.)

Lets say we wanted to go to a popular search engine website like “Google.” In the address box you would type: www.google.com and press the “enter” key on the keyboard.

using the internet bar s website
USING THE INTERNET – BAR’s Website

BAR’s website has a lot of useful information for Smog Check technicians and stations. The site has been recently been updated, and some new features were added. This site can provide you with information that can assist you in performing an inspection. Some of this site’s information is not available on any other website.

So let’s take a look at some of the information that is available:

accessing manufacturer websites tsbs
Accessing Manufacturer Websites - TSBs

Accepted engine performance/emission failure diagnostic procedures require the technician to check (early on in the process) for Technical Service Bulletins (TSBs)- usually after checking for Diagnostic Trouble Codes (DTCs). Often, the most up-to-date source for these TSBs is the manufacturer’s website.

Today, these websites can be accessed by the technician via the internet, for a nominal fee (and in some cases for free!)

accessing manufacturer websites tsbs1
Accessing Manufacturer Websites - TSBs

Q: So how can a TSB help me?

Imagine the following situation:

A technician has a 2004 1.6L Hyundai Accentthat has the followingDTC: P0130 (oxygen sensor malfunction). Without Checking for TSBs, the tech incorrectly replaces the O2 sensor with a new one –

same code reappears!

WHAT TO DO NOW?

accessing manufacturer websites tsbs2
Accessing Manufacturer Websites - TSBs

Had the technician checked the manufacturer’s website, he/she would have found the following TSB related to this code:

As you can see, this was not an O2 sensor failure issue, but an ECM reprogramming issue. Now the shop must suffer the loss of time and money (O2 sensor was not returnable) that resulted from an incorrect diagnosis and not following a sound diagnostic procedure.

Technical Service Bulletin

This bulletin supersedes TSB# 05-36-003-2 to correct DTC code in the title from P0530 to P0503.

Subject: 2000-2004 1.5L & 1.6L ACCENT P0130 (OXYGEN SENSOR) AND P0503 (SPEED SENSOR)

Group: ENGINE ELECTRICAL

Number: 06-36-002

Date: MAY, 2006

Model: 2000-2004 ACCENT

DESCRIPTION: Some 2000-2004 Accents with 1.5L SOHC and 1.6L DOHC engines may experience the following symptoms::

  • DTC P0130 (Oxygen Sensor Malfunction)
  • DTC P0503 (Speed Sensor Malfunction)
  • Reverse to Drive lurch while rolling backwards (On Automatic Transaxle equipped vehicles only)

This bulletin describes the procedure for updating the Engine Control Module (ECM) software to improve the above condition by using the Hi-Scan Pro.

VEHICLES AFFECTED:

Model: 2000-2004 ACCENT vehicles with 1.5L SOHC and 1.6L DOHC engines.

accessing manufacturer websites tsbs3
Accessing Manufacturer Websites - TSBs

OK, you have convinced me that TSBs have value, but I have never been to a manufacturer’s (mfg.) website before, where is it located and how do I access this information?

It is not as hard as you think, let’s take this process step-by-step. The first step is to find the specific manufacturer’s webpage address for the vehicle you are working on.

An organization called “The National Automotive Service Task Force” has provided a list of mfg. webpage addresses: www.nastf.org.

So let’s go there now!

accessing manufacturer websites getting an email address
Accessing Manufacturer Websites - Getting an Email Address

But I don’t have an email address,

how do I get one?

You can set up a “free” email account at various websites, some of which are:

  • www.hotmail.com
  • www.gmail.com
  • www.yahoo.com

Accessing Manufacturer Websites

Now that you know how to sign up to access a manufacturer’s website, let’s explore some the information you might find on a typical website:

other helpful websites
Other Helpful Websites

There are many other websites that can assist a Smog Check technician. One popular website is the “International Automotive Technicians Network” (www.I-ATN.com). This site’s ‘standard’ membership level is “free”. Let’s take a look at some of the features of this site that might be of value:
