(b) Disconnect the A35 front speed sensor 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.
Standard Voltage:

CHECK HARNESS AND CONNECTOR (FRONT SPEED SENSOR RH - BRAKE ACTUATOR ASSEMBLY) |
(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 A33 skid control ECU (brake actuator assembly) connector.
(c) Disconnect the A35 front speed sensor RH connector.
(d) Check both the connector case and the terminals for deformation and corrosion.
OK:
No deformation or corrosion.
(e) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
|
Tester Connection | Condition |
Specified Condition |
|---|---|---|
|
A35-2 (FR-) or A33-4 (FR-) - Body ground |
Always | 10 kΩ or higher |
| OK | | REPLACE FRONT SPEED SENSOR RH |
| NG | | REPAIR OR REPLACE HARNESS OR CONNECTOR |
