Engine Performance II Final Exam Questions and Answers Graded A+ Technician A says that DTCs beginning with a P0 are standardized per Global OBDII (Generic OBDII). Technician B says that OBDII standardized DTC's applies to DTC's beginning with P, B, C, and U. Who is correct? - Answers Tech A Technician A says that Freeze Frame data can be useful in retrieving calibration lookup information for ECM reprogramming. Technician B says that Mode $09 is responsible for reporting Vehicle and ECM information. Who is correct? - Answers Tech B Technician A says that the CCM (Comprehensive Component Monitor) checks for electrical shorts, opens, grounds and has rationality logic. Technician B says the CCM sets 2-trip DTC's only. Who is correct? - Answers Tech A Technician A says that Type A and B DTC's are required to set Freeze Frame data. Technician B says that Type A and B DTC's are emissions related DTC's. Who is correct? - Answers Both Technician A says the DLC3 is a standardized 14 pin OBDII connector. Technician B says that the DLC3 is required to be in a specified area for all OBDII vehicles. Who is correct? - Answers Tech B Technician A says that a catalyst damaging misfire will cause the check engine light to flash. Technician B says that the Catalyst monitor is a non-continuous monitor. Who is correct? - Answers Both Technician A says that enabling criteria must be met for certain monitors to run. Technician B says that test results for all pre-CAN non-continuous monitors can be found in Mode $05 data. Who is correct? - Answers Tech A Technician A says that a MIL (Malfunction Indicator Lamp) functional check includes the MIL being illuminated during the initial key on ignition cycle. Technician B says that a key cycle does not require an engine start. Who is correct? - Answers Both Technician A says that a CMPL monitor status means the monitor has passed testing with no failures. Technician B says that an INCMPL monitor status means the monitor has ran, failed a test and stopped running. Who is correct? - Answers Neither Technician A says that the catalyst monitor may have sequencing conditions that require the O2 monitor to run before it can. Technician B says that monitors rely on sensor data to report test results. - Answers Both Technician A says that 2010 and later vehicles require the use of Permanent DTCs. Technician B says that the MIL cannot be turned off on a vehicle with Permanent DTCs. Who is correct? - Answers Tech A Technician A says the In-Use Performance Tracking information is a function of Mode $09. Technician B says that Mode $10 ($0A) is for In-Use Performance Tracking. Who is correct? - Answers Tech A Technician A says the Federal Test Procedure (FTP) limit is 2.5x. Technician B says that FTP is 1.5x. Who is correct? - Answers Tech B A P0172 (Bank 1 System Too Rich) DTC is stored in Pending status. Technician A says this DTC will set as a Permanent DTC during the 2nd-trip failure. Technician B says the P0172 is part of the Fuel Monitor. Who is correct? - Answers Both Technician A says that the ECM can display substituted values when a generic scan tool (GST) is used. Technician B says that substituted values cannot be displayed in the Generic OBDII data stream. Who is correct? - Answers Tech B Technician A says that Global OBDII provides hundreds of "real time" data parameters in Mode $01. Technician B says that a manufacturer level scan tool must be used to gain complete access to all of the available parameter sets. Who is correct? - Answers Tech B Technician A says that Mode $06 data is decoded when using Techstream. Technician B says that Mode $06 data may not be available using a Generic Scan Tool. Who is correct? - Answers Both Technician A says that an Enhanced scan tool offers all factory scan tool information. Technician B says the Techstream Lite is an Enhanced scan tool. Who is correct? - Answers Neither Technician A says that checking the calibration information of the ECM is not an important step in the diagnostic process. Technician B says that Techstream can be used to update ECM's OBDII software. Who is correct? - Answers Tech B Technician A says that Active Tests in Techstream are bi-directional control tests. Technician B says that snapshots (recordings) can be taken during active testing. Who is correct? - Answers Both Technician A says Mode $08 is for testing of system components using a scan tool. Technician B says that the Generic Mode $08 feature does not offer any diagnostic value. Who is correct? - Answers Both Technician A says that Techstream Freeze Frame data is represented by a "snowflake" icon. Technician B says Freeze Frame data on Techstream is accessed from the DTC screen. Who is correct? - Answers Both Technician A says that the Misfire monitor is continuous monitor. Technician B says that the Misfire Monitor may have test results stored in the Mode $06 data portion of Techstream. Who is correct? - Answers Both Technician A says that Readiness Monitor Drive Patterns can be found under the associated DTC using TIS. Technician B says that the Readiness Monitor Drive Pattern should be used to validate repairs. Who is correct? - Answers Both Technician A says the Techstream can be used to force the EVAP monitor to run. Technician B says that EVAP monitor test results are viewed in Mode $07 data. Who is correct? - Answers Tech A Technician A says that live data is useful as a diagnostic tool. Technician B says that viewing too may live data parameters at once can cause the sampling rate of the data stream to decrease. Who is correct? - Answers Both Technician A says that a misfire is a lack of compression. Technician B says that a misfire is a lack of combustion. Who is correct? - Answers Tech B Technician A says the mechanical sealing condition of the engine should be checked before proceeding with misfire diagnostics. Technician B says that Techstream allows for compression testing on most 2005 and later MY vehicles. Who is correct? - Answers Both The following Cylinder Speed test results are reported by Techstream: #1: 147 / #2: 145 / #3: 183 / #4: 148 / #5: 178 / #6: 145
