PROCEDURE
|
1. |
CHECK HARNESS AND CONNECTOR (SENSOR GROUND 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 A36 front speed sensor LH 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:
|
Tester Connection |
Condition |
Specified Condition |
|---|---|---|
|
A36-1 (FL+) - A36-2 (FL-) |
Ignition switch ON |
11 to 14 V |
| NG |

2. |
CHECK HARNESS AND CONNECTOR (FRONT SPEED SENSOR LH - 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 A34 skid control ECU (brake actuator assembly) connector.
(c) Disconnect the A36 front speed sensor LH connector.
(d) Check both the connector case and the terminals for deformation and corrosion.
OK:
