CHECK HARNESS AND CONNECTOR (SENSOR POWER SOURCE CIRCUIT) |
|
(a) Make sure that there is no looseness at the locking part and the connecting part of the connectors. OK: The connector is securely connected. |
|
(b) Disconnect the u2 rear speed sensor RH (rear axle hub and bearing assembly RH) connector.
(c) Check both the connector case and the terminals for deformation and corrosion.
OK:
No deformation or corrosion.
(d) Turn the ignition switch to ON.
(e) Measure the voltage according to the value(s) in the table below.
