Note. The Evaporative System Check (Automatic Mode) consists of 5 steps performed automatically by the Techstream. It takes a maximum of approximately 18 minutes. Do not perform the Evaporative System Check when the fuel tank is more than 90% full because the cut-off valve may be closed, making the fuel tank leak check unavailable. Do not run the engine during this operation. When the temperature of the fuel is 35°C (95°F) or more, a large amount of vapor forms and any check results become inaccurate. When performing the Evaporative System Check, keep the fuel temperature below 35°C (95°F).

6. CHECK HARNESS AND CONNECTOR Connect the park/neutral position switch connector. Disconnect the ECM connector. Turn the ignition switch to ON, and measure the voltage according to the value(s) in the table below when the shift lever is moved to each position. Standard voltage Shift Position Tester Connection Specified Condition P B50-24 (P) - Body ground 11 to 14 V Except P Below 1 V N B50-27 (N) - Body ground 11 to 14 V Except N Below 1 V R B50-25 (R) - Body ground 11 to 14 V * Except R Below 1 V D and S B50-26 (D) - Body ground 11 to 14 V Except D and S Below 1 V HINT: * : The voltage will drop slightly due to lighting up of the back up light. Reconnect the ECM connector. NG --> REPAIR OR REPLACE HARNESS OR CONNECTOR OK: Go to next step
7. CHECK HARNESS AND CONNECTOR Disconnect the transmission control switch connector of the shift lock control unit assembly. Turn the ignition switch to ON. Measure the voltage between the terminals. Standard voltage Tester Connection Switch Condition Specified Condition 3 - Body ground Ignition switch ON 11 to 14 V Reconnect the transmission control switch connector.
