- Start the engine.
- Turn on the cruise control main switch, then drive the vehicle to speeds over 25 mph (40km/h) with the cruise control. Does the cruise control operate ? YES - Go to step 3. NO - Check the cruise control unit or cruise control actuator.
- Measure the voltage between terminal of the cruise control unit connector and ground. Is there approx. 1V? YES - Go to step 4. NO - Replace the cruise control unit.
- Measure the voltage between the No.8 terminal of the TCM connector and ground. Is there approx. 1V? NO - Repair short or open in the wire between the No.8 terminal and cruise control unit.
THE MICRO 570 ANALYZER
The MICRO 570 Analyzer provides the ability to test the charging and starting systems, including the battery, starter and generator.
| CAUTION | Because of the possibility of personal Injury, always use extreme caution and appropriate eye protection when working with batteries. |

- Connect the tester to the battery. Red clamp to battery positive (+) terminal. Black clamp to battery negative (-) terminal. CAUTION: Connect clamps securely. If "CHECK CONNECTION" message is displayed on the screen, reconnect clamps securely.
- The tester will ask if the battery is connected "IN A VEHICLE" or "OUT OF A VEHICLE". Make your selection by pressing the arrow buttons; then press ENTER.
- Choose either CCA or CCP and press the ENTER button. NOTE: CCA: Cold cranking amps, is an SAE specification for cranking batteries at 0°F (-18°C). CCP: Cold cranking power, is an SAE specification for Korean manufacturer's for cranking batteries at 0°F (-18°C).
- Set the CCA value displayed on the screen to the CCA value marked on the battery label by pressing up and down buttons and press ENTER.
- The tester (Micro570) displays battery test results including voltage and battery ratings. A relevant action must be taken according to the test results by referring to the battery test results as shown in «BATTERY TEST RESULTS»(ref-263270-S05669844282007090500000) . NOTE: The battery ratings (CCA) displayed on the tester must be identical to the ratings marked on the battery label.
- To conduct starter test, continuously, press ENTER.
