IMPORTANT NOTES AND REMINDERS:

• When directed to replace the engine oil and filter, always use the specified viscosity. DO NOT
supplement the engine oil with any additives.
• When installing new cam carrier oil filters, use caution to not press them into the cam carriers
any deeper than flush with the machined cylinder head mating surface.
• The wiring connector chart referenced throughout the Troubleshooting Charts (CHAPTER 8) is
found at the end of this TSB.

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 “defi-
nitely 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 ex-
ample 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).

(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 strat-
egy is able to catch such cases.
