-- Introduction General Information In--43 Checking Monitor Status 1. Introduction The Monitor Status (Mode 06 data) allows the OBD scan tool to display the monitor result, test value and test limit (malfunction criterion). A problem in the emission--related components such as the catalyst, EVAP and thermostat can be found by comparing the test value and test limit. The monitor status information is included under “Decoding Mode 06 Data” (see page In-44 ). The ECM (PCM) monitors the emission--related components. After the monitor, the ECM stores the monitor results and test values. The monitor result indicates whether the component is functioning normally or not (PASS orFAIL).
The test value is the value that was used to determine the monitorresult. When the test value is inside the test limit, the ECM determines the component is functioning normally (PASS). If the test value is outside the test limit, the ECM determines the component is malfunctioning (FAIL). 2. Procedure NOTICE: The monitor results and test values are cleared when the ignition switch is OFF. (a) Connect the hand--held tester to the DLC3. (b) Turn the ignition switch and hand--held tester switch ON. (c) Clear the DTCs. (d) Run the vehicle in accordance with the applicable drive pattern described in “OBD Monitor Drive Pat- tern” (see page In-13 ). In011--01 (e) Select from the tester menus:
DIAGNOSIS, ENHANCED OBD II, MONITOR INFO and MONITOR RESULT. The monitor result appears after the component name. INCMP: The component has not been monitored yet. PASS: The component is functioning normally. FAIL: The component is malfunctioning. (f) Confirm that the component is set to either PASS or FAIL. MONITOR RESULT CATALYST#1 B1 . INCMP CATALYST#1 B2 .

A20402 (g) Select the component and press ENTER. If TLT is 0, the component is malfunctioning when the test value is high- er than the test limit.
If TLT is 1, the component is malfunc- tioning when the test value is lower then the test limit. VAL: The test value. LMT: The test limit. TLT: The test limit type. (h) Compare the test value with the test limit. The test value is usually significantly higher or lower then the test limit. If the test value is on the borderline of the test limit, there is a potential malfunction in the component. HINT: The monitor result might on rare occasions be PASS even if the MIL is illuminated. This indicates the system malfunctioned on a previous driving cycle. This might be caused by an intermit- tent problem.
