Inspection Procedure

WARNING: This page is about a different car, the 2007 Toyota Camry Solara. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
  • Turn the ignition switch off before measuring the resistance of the CAN main wires and CAN branch wires.
  • After the ignition switch is turned off, check that the key reminder warning system and light reminder warning system are not operating.
  • Before measuring the resistance, leave the vehicle as is for at least 1 minute and do not operate the ignition switch, any other switches or the doors. If doors need to be opened in order to check connectors, open the doors and leave them open.

HINT:

Operating the ignition switch, any other switches, or any doors triggers related ECU and sensor communication on the CAN. This communication will cause the resistance value to change.

  1. CHECK CAN BUS LINE FOR DISCONNECTION (STEERING SENSOR BRANCH WIRE) 
    1. Turn the ignition switch to the LOCK position.
    2. Disconnect the steering sensor connector (S9).
    3. Measure the resistance according to the value(s) in the table below.

      Standard resistance 

      CAN BUS LINE FOR DISCONNECTION (STEERING SENSOR BRANCH WIRE)

      Tester Connection Condition Specified Value
      S9-10 (CANH) - S9-9 (CANL) Ignition switch off 54 to 69 Ω

    NG: REPAIR OR REPLACE STEERING SENSOR BRANCH WIRE OR CONNECTOR (CAN-H, CAN-L) 

    OK: Go to next step 

  2. CHECK WIRE HARNESS (IG, ESS) 
    1. Measure the resistance according to the value(s) in the table below.

      Standard resistance 

      WIRE HARNESS (IG, ESS) RESISTANCE

      Tester Connection Condition Specified Value
      S9-2 (ESS) - Body ground Always Below 1 Ω
    2. Measure the voltage according to the value(s) in the table below.

      Standard voltage 

      WIRE HARNESS (IG, ESS) VOLTAGE

      Tester Connection Condition Specified Value
      S9-1 (IG) - Body ground Ignition switch on 10 to 14 V

    NG: REPAIR OR REPLACE WIRE HARNESS OR CONNECTOR 

    OK: REPLACE STEERING SENSOR
