Chapter 4 On-Board Diagnostics (OBD) Your new MICROSCAN conforms to Global OBD (OBD-II in North America and EOBD in Europe) standards, and is designed for testing compliant vehicles. This chapter describes Global OBD. 4.1 Global OBD and What it Means Many countries have enacted strict emission related regulations that will drive increased technology into the modern automobile in order to reduce the exhaust emissions.
On-Board Diagnostics (OBD) OBD-II/EOBD Limitations 4.1.2 EOBD Start-up Phase The European vehicle manufacturers also needed time to phase in and develop EOBD tests and software in their electronic control modules (ECMs). Some of the manufacturers already had experience with the USA OBD-II. Others may still have to improve their most recent software versions. This means that EOBD is experiencing similar phase in problems as OBD-II, with some 2001 and 2002 vehicles having limited EOBD functionality. 4.
On-Board Diagnostics (OBD) Diagnostic Services Introduction 4.4.1 What is CAN? CAN stands for Controller Area Network and means that control units are part of a network and can interchange data. Although some car manufacturers have used CAN for some years for communication between electronic control modules (ECMs), it was not directly connected to the diagnostic connector.
On-Board Diagnostics (OBD) Diagnostic Services Introduction Table 4-2 Continuous or Non-continuous monitors (sheet 2 of 2) Readiness Monitor Remark Catalyst monitoring † Heated catalyst monitoring † Evaporative system monitoring † Secondary air system monitoring † A/C system refrigerant monitoring † Oxygen sensor monitoring † Oxygen sensor heater monitoring † EGR system monitoring † † Will only be monitored if the correct conditions are met.
On-Board Diagnostics (OBD) Diagnostic Services Introduction Repair validation Use the following procedure to validate a repair. z To validate the repair: 1. Perform a drive cycle (generic or vehicle specific). 2. Check Service $07 (refer to 4.6.7: ‘Service $07: Emission-related DTCs detected during Current or Last Completed Drive Cycle (Pending Codes)’ on page 25) and Service $03 (refer to 4.6.3: ‘Service $03: Emission-related DTCs’ on page 18).
On-Board Diagnostics (OBD) Diagnostic Service Definitions 4.6 Diagnostic Service Definitions 4.6.1 Service $01: Display Current Data The ECMs transmit the data value stored by the system. The data is commonly called PID (Parameter IDentification). All of the sensors parameters show the actual readings. Not default or substitute values used by the system, because of a fault with that sensor. Depending on the ECM and amount of parameters selected, data update rates may vary.
On-Board Diagnostics (OBD) Diagnostic Service Definitions 4.6.3 Service $03: Emission-related DTCs The purpose of this service is to enable the scan tool to obtain stored DTCs from the power train ECMs that are emission-related. The OBD-I ECM primarily identifies a faulty signal or a faulty sensor using three steps: • Signal or component shorted to ground • Signal or component shorted to battery positive • No signal or component (open circuit) For each of these tests, a specific trouble code is set.
On-Board Diagnostics (OBD) Diagnostic Service Definitions P0 237 Position 4 & 5 Position 3 Position 2 Position 1 Figure 4-3 Example: DTC “P0237” In this example, definitions listed for Position 3 are only valid for DTCs starting with “P”. For other codes (C, B, U) there are other definitions. Please refer to ruling OBD standards for more information. Code Ranking OBD-II/EOBD Codes have a priority according to their emission severity, with higher priority codes overwriting lower priority codes.
On-Board Diagnostics (OBD) Diagnostic Service Definitions Table 4-4 Reset Information (sheet 2 of 2) Service Items to reset $03 Confirmed diagnostic trouble codes $05 Oxygen sensor test data $06 Specific on-board monitoring test results $07 Pending diagnostic trouble codes The following may occur as well: • It may also erase engine management adaptive memory (some vehicle manufacturers only) when codes are cleared.
On-Board Diagnostics (OBD) Diagnostic Service Definitions The scan tool checks if the readiness status of oxygen sensors is completed. If the test is not completed, the scan tool displays a warning. $08 Oxygen Sensor Output $04 Rich $01 $02 $03 $07 Lean Numbers Refer to Test ID $06 $05 $0A $09 Figure 4-4 Test ID Values Example i NOTE: Refer to Table 4-5 for an explanation of the individual Test ID numbers.

On-Board Diagnostics (OBD) Diagnostic Service Definitions 4.6.6 Service $06: Specific Monitored Systems Test Results The purpose of this service is to allow access to the test results for on-board diagnostic monitoring tests of specific components or systems that are continuously monitored (CAN only) and non-continously monitored. The misfire monitor is an example of a continuously monitored system, and the catalyst system would be an example of a non-continously monitored system.
On-Board Diagnostics (OBD) Diagnostic Service Definitions Non CAN Protocol The vehicle manufacturer is responsible for assigning Test IDs and Component IDs for tests of different systems and components. The latest test results are to be retained, even over multiple ignition OFF cycles, until replaced by more recent test results. Test results are requested by Test ID.
On-Board Diagnostics (OBD) Diagnostic Service Definitions Test results for these components or systems are reported in the same format as the DTCs in Service $03; refer to “Service $03: Emission-related DTCs” on page 18. The intended use of this service is to assist the service technician after a vehicle repair and after clearing diagnostic information, by reporting test results after a single driving cycle. • If a test failed during the driving cycle, the DTC associated with that test will be reported.
On-Board Diagnostics (OBD) Diagnostic Service Definitions The completion value tracks the number of times that all conditions necessary for a specific monitor to detect a malfunction have been encountered. The condition value indicates the number of times that the vehicle has been operated in the specified conditions. OBD Monitoring Conditions—displays the number of times that the vehicle has been operated in the specified OBD monitoring conditions.

Connect a new 9-volt battery to the wiring connector and fit the battery into the compartment. 5. Fit the center tab on the battery cover into the slot on the housing and pivot the cover down. 6. Slide the battery cover into position so that it locks into place on the housing. Note the following safety warnings when installing batteries. ! WARNING Risk of personal injury or harm.
Appendix A Troubleshooting OBD-II/EOBD vehicles have few problems communicating with a scan tool. However, problems with the wiring or other circuit parts on the vehicle may prevent communication between the scan tool and the vehicle electronic control module (ECM). When this happens, a “no communication” message displays on the screen. A vehicle that fails to perform a test can also be a symptom of a driveability problem. A.
Troubleshooting Communication Problems some manufacturers use the SAE J1850 BUS+ line but not the BUS-, while others use the ISO 9141 K-LINE, but not the L-LINE. See the table below.
Troubleshooting Communication Problems The meter should read battery voltage. This tests the battery voltage supply to the ECM. 3. ECM Communication Lines—Remember, a stuffed pin does not necessarily predict the signal type. First determine if the vehicle uses J1850, ISO 9141, ISO 14230 or CAN (ISO 15765) and then determine if it uses both associated lines, or just one. For ISO 9141 and ISO 14230 the K-LINE must be used, while the L-LINE is optional.
