Toyota RAV4. Ecm communication stop mode (2005/11-2006/01)


Inspection procedure

Notice:

Hint:

Operating the ignition switch, any switches or any doors triggers related ecu and sensor communication with the can, which causes resistance variation.

  1. Check wire harness (ecm - battery and body ground)

  1. Disconnect the a9 and b30 ecm connectors.
  2. Measure the resistance of the wire harness side connector.

Standard resistance


  1. Measure the voltage of the wire harness side connector.

Inspection
Inspect cylinder block for warpage Using a precision straightedge and feeler gauge, measure the warpage of the surface that is in contact with the cylinder head gasket. Maximum warpage: 0.05 Mm (0.0020 In.) If the warpage is greater than the maximum, replace the cylinder block ...

Source voltage drop
Description The srs is equipped with a voltage-increase circuit (dc-dc converter) in the center airbag sensor in case the source voltage drops. When the source voltage drops, the voltage-increase circuit (dc-dc converter) functions to increase the voltage of the srs to a normal working lev ...

General information
A large number of ecu controlled systems are used in the rav4. In general, ecu controlled systems are considered to be very intricate, requiring a high level of technical knowledge to troubleshoot. However, most problem checking procedures only involve inspecting the ecu controlled system's circ ...
