, on the other hand, uses the factory diagrams. That saves a lot of time because you don’t have to refer back to the component locator or circuit locations. redraws factory wiring diagrams in color and includes the component, splice and ground locations right in their diagrams. Pricing: - 1 month subscription $19.95 per vehicle 1-year subscription $29.95 per vehicle 4-year subscription $44.95 per vehicle - 1-year $29.95 subscription: additional vehicles $19/95 each 5-year $49.95 subscription: additional vehicles $34.95 each Which one should YOU choose? If you’re tracking down a wiring issue, is the better choice. In most cases, their diagrams are right from the factory manuals. They include wiring diagrams and technical service bulletins. Get the BEST auto repair information and are professional-grade shop manuals-period. Even if you’ve made a successful repair and have cleared the codes in Mode $04, these codes will remain in memory until the computer has completed its own system test. Mode 10 allows a scan tool to obtain “permanent codes.” These are codes only the module can clear. When you enter this mode, you are telling the PCM/ECM to provide access to emissions-related codes with permanent status after a clear/reset emission related diagnostic information service. Mode $09 provides vehicle identification number and calibration numbers from all emissions-related electronic modules. When you enter this mode, you are telling the PCM/ECM to provide vehicle information. Mode $08 allows a scan tool to do bidirectional control of an onboard system or test. When you enter this mode, you are telling the PCM/ECM to access control of on-board system, test or component. Mode $07 is the “pending codes” selection. The purpose of Mode $07 is to allow the scan tool to access codes that have been stored on the first drive cycle AFTER a PCM/ECM reset. When you enter this mode, you are telling the PCM/ECM to provide access to emission-related trouble codes detected during the current or last completed driving cycle. The only way to understand what you are seeing is use a scan tool that defines all of the data for you or to print out the Mode $06 information from a shop manual. There is NO industry standard data for Mode $06 test. It allows access to test results for on-board diagnostic monitoring tests of specific components that are continuously monitored (misfire monitoring) and non-continuously monitored systems. When you enter this mode, you choose which system you want to monitor. When you enter this mode, you are telling the PCM/ECM to provide access to on-board monitoring test results for specific monitored systems. For those cars, you’ll need to go directly to Mode $06. The difference is that Mode $05 information is not available on vehicles using the Controller Area Network (CAN) system. You can obtain the same information by using Mode $06. When you enter this mode you get access to the engine control module’s oxygen sensor monitoring test results. When you enter this mode, you are telling the PCM/ECM to provide oxygen sensor monitoring test results. It also resets all readiness monitors and turns off the check engine light. When you enter this mode, you’re clearing not only the trouble codes, but also the freeze-frame data and all stored test data. When you enter this mode, you are telling the PCM/ECM to clear/reset emissions-related diagnostic information. The purpose of Mode $03 is to allow your scan tool to access codes stored in the emissions-related modules. When you enter this mode, you are telling the PCM/ECM to provide emissions related trouble codes.
