END END Continued… Bulletin Number: 02-163-16R; Revised: 06/27/19 Page 17 APPENDIX “A” During diagnosis of these AVCS-related DTCs, step 3 (or step 4) begins with the Check question: “Is the diagnostic value of applicable AVCS greater than or equal (≥) to 1000?” The next question is: “If the value is less than 1000, is the value definitely greater than the other AVCS values? What defines “definitely greater”? What judgement criteria should be used to determine if the value displayed is OK or NG? The following will help make this step easier to understand and eliminate confusion about this step of the diagnosis. Use the formula below to determine whether the AVCS value measured is OK (X < Z) or NG (X > Z) by comparing the suspect bank value (X) to the solution value (Z). Formula: (Y) x 1.5 + 100 = Z • Y= comparison bank • Z= solution For this example, we will use the Troubleshooting Chart for P000A / P0011 with the trouble suspected to be on the Bank 1 (P000A) side of the engine. The following (example) values will be assigned: • Observed (suspect) Bank 1 SSM (MODE$06) Value = 900 and we will call that (X). • Observed (comparison) Bank 2 SSM (MODE$06) Value = 300 and we will call that (Y). Example calculation #1: X = 900 and Y = 300 (a large difference between B1 and B2 values) Calculation: (Y) 300 x 1.5 + 100 = 550 (Z). Since (X) 900 is greater than (Z) 550, the result in this example is “NG”. Therefore, in this example where the value (X) is definitely greater, the Technician should proceed to the next step on the Troubleshooting chart. For this example, we will use the Troubleshooting Chart for P000C / P0021 with the trouble suspected to be on the Bank 2 (P000C) side of the engine. The following (example) values will be assigned: • Observed (suspect) Bank 2 SSM (MODE$06) Value = 900 and we will call that (X). • Observed (comparison) Bank 1 SSM (MODE$06) Value = 800 and we will call that (Y). Example calculation #2: X = 900 and Y = 800 (a small difference between B1 and B2 values): Calculation: (Y) 800 x 1.5 + 100 = 1300 (Z). Since (X) 900 is less than (Z) 1300, the result in this example is “OK”. Therefore, in this example where the value (X) is not definitely greater, the Technician should proceed with the work described in the “NO” column of the Troubleshooting chart for this test (change oil, idle engine for 5 minutes, change oil again and the oil filter).

Clear the memory by using the SSM (2). Start the engine in a warmed up condition (coolant temp. should be more than 160 deg.F.). (3). Idling the engine for 3 min. or more. (4). Accelerate to 50 mph. (5). Keep the acceleration pedal at 0% for 5 sec. then move to 20% and hold for 5 seconds. Repeat this mode for 20 minutes or more. The vehicle speed should be kept around 50mph while in this mode. (The diagnosis process is completed repeatedly during this step. This step requires 2 people. One person should monitor the diagnostic value while another person is performing the driving cycle because the diagnostic value cannot be saved). (6). Foot off accelerator pedal (0%) and decelerate for more than 5 seconds. (The learning process is completed during this part). (7). Idle the engine and check the SSM data (Initial position learning value, diagnosis value). (8). If the SSM shows the data is OK, turn the engine off to finish the procedure. *Remarks: +Acceleration level can be changed depending on the traffic situation. +If no diagnosis data is memorized, perform driving cycle again without turning the engine off. CHAPTER 6: OBD MODE $06 Monitor Read out diagnosis value of OBD MODE&06 monitor: Mode$06 stands for “Test result for continuously and non-continuously monitored system supported” and one of the OBD-II diagnosis modes. It shows diagnosis value “Val.”, threshold, ”Min.”, “Max.” and diagnosis test result: “Result”. “MID” stands for OBD Monitor ID and shows items being tested. MID $35 means Right bank [Bank 1] AVCS test and MID $36 means Left bank [Bank 2] AVCS test. “TID” stands for The Test ID which shows specific test item being run. $8B and $8C are positive and negative side of the intake AVCS slow response. $8D and $8E are positive and negative side of the exhaust AVCS slow response. While the test is not completed, the Result shows “-“. If it is completed, “OK” or “NG” is displayed and the diagnostic test is repeated. “Min” and “Max” is threshold of normal range. If the diagnosis value is greater than the threshold, then “NG” is displayed and MIL is turned on. The inspection procedure in this bulletin uses the diagnosis value for judgment of the symptom duplication or completion of the repair because the trouble symptom is intermittent and sometimes hard to duplicate. Threshold value of the diagnosis value for the judgment is newly setup and smaller than the criteria of MIL ON. Therefore, it is possible to judge the trouble even though there is no MIL condition. For example: the threshold is “4000” deg. in the table described in Chapter 7.3. The judgment criteria in the troubleshooting in Chapter 4 is “1000”. That means if the diagnosis value “Val.” is greater than 4000, then MIL turns on. However, if the “Val.” is greater than 1000, it should be judged failure of the AVCS system. The case completely and constantly failure the “Val.” should be greater than 4000, but in the case of intermittent or slightly failure case, it could be between 1000 and 4000. This strategy is able to catch such cases.
