ground Constant Below Ω 16 (B+) – Body ground Constant to 14 V HINT: If the screen displays UNABLE TO CONNECT TO VEHICLE after you have connected the cable of the hand–held tester to the DLC3, turned the ignition switch ON and used the hand–held tester, there is a problem on the vehicle side or tester side S If communication is normal when the tester is connected to another vehicle, inspect the DLC3 of the original vehicle S If communication is still impossible when the tester is connected to another vehicle, the problem is probably in the tester itself, so consult the Service Department listed in the tester’s manual (b) Check the battery voltage Standard: 11 to 14 V If the voltage is below 11 V, replace the battery before proceeding Hand–held Tester A82518 LEXUS RX330/RX300 REPAIR
