Inspection Procedure

2008 Toyota Camry XLE, 2.4 ESECTION Inspection Procedure
NOTE:
  • Turn the ignition switch off before measuring the resistance of the CAN main wire 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 triggers related ECU and sensor communication on the CAN, which would cause resistance reading variations.

  1. CHECK OPEN IN CAN BUS WIRE (CENTER AIRBAG SENSOR BRANCH WIRE) 
    1. Turn the ignition switch off.
    2. Disconnect the center airbag sensor connector.
    3. Measure the resistance according to the value(s) in the table below.

      Standard resistance 

      RESISTANCE REFERENCE

      Tester Connection Condition Specified Value
      E30-13 (CANH) - E30-22 (CANL) Ignition switch off 54 to 69 Ω

    NG: REPAIR OR REPLACE CENTER AIRBAG SENSOR BRANCH WIRE OR CONNECTOR 

    OK: Go to next step 

  2. CHECK WIRE HARNESS (IG2, E1, E2) 
    1. Measure the resistance according to the value(s) in the table below.

      Standard resistance 

      RESISTANCE REFERENCE

      Tester Connection Condition Specified Value
      E30-25 (E1) - Body ground Always Below 1 Ω
      E30-26 (E2) - Body ground Always Below 1 Ω
    2. Measure the voltage according to the value(s) in the table below.

      Standard voltage 

      VOLTAGE SPECIFICATION

      Tester Connection Condition Specified Value
      E30-21 (IG2) - Body ground Ignition switch on (IG) 10 to 14 V
