Inspection Procedure

WARNING: This page is about a different car, the 2005 Toyota Sienna. However, it is still accessible from the selected car via links, so may be relevant.

CHECK RESISTANCE (CANL - CANH OF DLC3)
1. Measure the resistance between the terminals CANL and CANH of the DLC3.
RESISTANCE

A 54 to 68 Ω

B 1 MΩ or more

1. NG: REPLACE JUNCTION CONNECTOR
2. OK: REPAIR OR REPLACE HARNESS OR CONNECTOR
CHECK TERMINAL VOLTAGE (YAW RATE SENSOR CONNECTOR)
1. Disconnect the yaw rate sensor connector.
2. Turn the ignition switch ON.
3. Measure the voltage between terminals IG and GND of the yaw rate sensor connector.
  OK:
  
  Voltage: 10 to 14 V
