Mode 6 Data

2GR-FE ENGINE CONTROL: SFI SYSTEM: CHECKING MONITOR STATUS

CHECKING MONITOR STATUS

The purpose of the monitor result (mode 06) is to allow access to the results for on-board diagnostic monitoring tests of specific components/systems that are not continuously monitored. Examples are catalyst, evaporative emission (EVAP) and thermostat.
The monitor result allows the OBD II scan tool to display the monitor status, test value, minimum test limit and maximum test limit. These data are displayed after the vehicle has been driven to run the monitor.
When the test value is not between the minimum test limit and maximum test limit, the ECM (PCM) interprets this as a malfunction. When the component is not malfunctioning, if the difference of the test value and test limit is very small, the component will malfunction in the near future.
Perform the following instructions to view the monitor status. Although this instruction references the Toyota diagnostic tester, it can be checked using a generic OBD II scan tool. Refer to your scan tool operator's manual for specific procedures.
1. PERFORM MONITOR DRIVE PATTERN
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON.
(c) Turn the Techstream on.
(d) Clear the DTCs DTC Check / Clear.
(e) Run the vehicle in accordance with the applicable drive pattern described in Readiness Monitor Drive Pattern Monitors, Trips, Drive Cycles and Readiness Codes. Do not turn the ignition switch off.
NOTICE: The test results will be lost if the ignition switch is turned off.

2. ACCESS MONITOR RESULT
(a) Enter the following menus: Powertrain / Engine / Monitor / Result. The monitor status appears after the component name.
- Pass: The component is functioning normally.
- Fail: The component is malfunctioning.

(b) Confirm that the component is either Pass or Fail.
(c) Select the component and press ENTER. The accuracy test value appears if the monitor status is either Pass or Fail.
3. CHECK COMPONENT STATUS
(a) Compare the test value with the minimum test limit (MIN LIMIT) and maximum test limit (MAX LIMIT).
(b) If the test value is between the minimum test limit and maximum test limit, the component is functioning normally. If not, the component is malfunctioning. The test value is usually significantly higher or lower than the test limit. If the test value is on the borderline of the test limit, the component will malfunction in the near future.
HINT: The monitor result might on rare occasions be Pass even if the Malfunction Indicator Lamp (MIL) is illuminated. This indicates the system malfunctioned on a previous driving cycle. This might be caused by an intermittent problem.

4. MONITOR RESULT INFORMATION
If you use a generic scan tool, multiply the test value by the scaling value listed below.
