PROCEDURE
1. | 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 b4 rear speed sensor LH (rear axle hub and bearing assembly LH) connector.
(c) Check both the connector case and the terminals for deformation and corrosion.
OK:
No deformation or corrosion.
(d) Turn the engine switch on (IG).
(e) Measure the voltage according to the value(s) in the table below.
Standard Voltage:
Tester Connection | Condition | Specified Condition |
---|---|---|
b4-2 (LA+) - b4-1 (LA-) | Engine switch on (IG) | 11 to 14 V |
Result | Proceed to |
---|---|
OK | A |
NG (w/o AVS) | B |
NG (w/ AVS) | C |
A | REPLACE REAR AXLE HUB AND BEARING ASSEMBLY LH |
C | GO TO STEP 4 |
|
2. | 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 bN2 skid control sensor wire LH (No. 2 parking brake wire assembly) connector.
(c) Check both the connector case and the terminals for deformation and corrosion.
OK:
No deformation or corrosion.
(d) Turn the engine switch on (IG).
(e) Measure the voltage according to the value(s) in the table below.
Standard Voltage:
Tester Connection | Condition | Specified Condition |
---|---|---|
bN2-1 (RL+) - bN2-2 (RL-) | Engine switch on (IG) | 11 to 14 V |
OK | REPLACE NO. 2 PARKING BRAKE WIRE ASSEMBLY |
|
3. | CHECK HARNESS AND CONNECTOR (NO. 2 PARKING BRAKE WIRE ASSEMBLY - 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 A40 skid control ECU (brake actuator assembly) connector.
(c) Disconnect the bN2 skid control sensor wire LH (No. 2 parking brake wire assembly) 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 |
---|---|---|
bN2-1 (RL+) or A40-39 (RL+) - Body ground | Always | 10 kΩ or higher |
OK | REPLACE BRAKE ACTUATOR ASSEMBLY |
NG | REPAIR OR REPLACE HARNESS OR CONNECTOR |
4. | 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 bN6 skid control sensor wire LH (No. 2 parking brake wire assembly) connector.
(c) Check both the connector case and the terminals for deformation and corrosion.
OK:
No deformation or corrosion.
(d) Turn the engine switch on (IG).
(e) Measure the voltage according to the value(s) in the table below.
Standard Voltage:
Tester Connection | Condition | Specified Condition |
---|---|---|
bN6-1 (RL+) - bN6-2 (RL-) | Engine switch on (IG) | 11 to 14 V |
OK | REPLACE NO. 2 PARKING BRAKE WIRE ASSEMBLY |
|
