1. READ DATA LIST
HINT: Using the intelligent tester to read the Data List allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic time.
HINT: "3" is OK but "1" is NG → ECM failure "1" is OK but "2" is NG → DTC output or ECM failure "3" is OK but cruise indicator does not turn on → CRUISE MAIN indicator, wire harness, or ECM failure
2. PERFORM ACTIVE TEST
HINT: Using the intelligent tester to perform Active Tests allows relays, VSVs, actuators and other items to be operated without removing any parts. This non-intrusive functional inspection can be very useful because intermittent operation may be discovered before parts or wiring is disturbed. Performing Active Tests early in troubleshooting is one way to save diagnostic time. Data List information can be displayed while performing Active Tests.
HINT: The ignition switch must be turned on to proceed with the ACTIVE TEST using the intelligent tester.
