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 terminal CANL and CANH of the DLC3.
RESISTANCE

A 1 MΩ or more

B 54 to 68 Ω

1. NG: Go to step 6
2. OK: IF THE SAME CODE IS STILL OUTPUT AFTER THE DTC IS DELETED, CHECK THE CONTACT CONDITION OF EACH CONNECTION
CHECK TERMINAL VOLTAGE (STEERING ANGLE SENSOR CONNECTOR)
1. Disconnect the steering angle sensor connector.
2. Turn the ignition switch ON.
3. Measure voltage between terminals 1 and 2, 2 and 3 of the steering angle sensor harness side connector.
  OK:
  
  Voltage: 10 to 14 V
