LS 600h V8-5.0L (2UR-FSE) Hybrid (2008)
NOTE: *: Before measuring the resistance, leave the vehicle as is for at least 1 minute and do not operate the power switch, any other
switches, or the doors.
If the result is not as specified, the DLC3 may have a malfunction. Repair or replace the harness and connector.
(b) Connect the cable of the intelligent tester or Techstream to the DLC3, turn the power switch ON (IG) and attempt to use the tester. If the
display indicates that a communication error has occurred, there is a problem either with the vehicle or with the tester.
HINT:
-
If communication is normal when the tester is connected to another vehicle, inspect the DLC3 of the original vehicle.
-
If communication is still not possible when the tester is connected to another vehicle, the problem may be in the tester itself. Consult the
Service Department listed in the tester's instruction manual.

ELECTRONIC CIRCUIT INSPECTION PROCEDURE
1. BASIC INSPECTION
(a) WHEN MEASURING RESISTANCE OF ELECTRONIC PARTS
(1) Unless otherwise stated, all resistance measurements should be made at an ambient temperature of 20°C (68°F). Resistance measurements
may be inaccurate if measured at high temperatures, i.e. immediately after the vehicle has been running. Measurements should be made
after the engine has cooled down.
(b) HANDLING CONNECTORS
(1) When disconnecting a connector, first squeeze the mating halves tightly together to release the lock, and then press the lock claw and
separate the connector.
(2) When disconnecting a connector, do not pull on the harnesses. Grasp the connector directly and separate it.
(3) Before connecting a connector, check that there are no deformed, damaged, loose or missing terminals.
(4) When connecting a connector, press firmly until it locks with a "click" sound.
(5) If checking a connector with a TOYOTA electrical tester, check the connector from the backside (harness side) using a mini test lead.
-
As a waterproof connector cannot be checked from the backside, check it by connecting a sub-harness.
-
Do not damage the terminals by moving the inserted tester needle.
