CONFIRMATION DRIVING PATTERN

NOTICE:

When performing the normal judgment procedure, make sure that the driver door is closed and is not opened at any time during the procedure.


HINT:
·

After repair has been completed, clear the DTC and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.

·

When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.



1.

Connect the GTS to the DLC3.

2.

Turn the ignition switch to ON and turn the GTS on.

3.

Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).

4.

Turn the ignition switch off.

5.

Turn the ignition switch to ON (READY) and turn the GTS on.

6.

Wait for 1 second or more. [*]

HINT:

[*]: Normal judgment procedure.

The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.


7.

Enter the following menus: Chassis / Brake/EPB* / Utility / All Readiness.

*: Electric Parking Brake System

8.

Check the DTC judgment result.

HINT:
·

If the judgment result shows NORMAL, the system is normal.

·

If the judgment result shows ABNORMAL, the system has a malfunction.

·

If the judgment result shows INCOMPLETE, perform driving pattern again.

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 o3 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.

Standard Voltage:
Tester Connection Condition Specified Condition
o3-2 (RR+) - o3-1 (RR-) Ignition switch ON 11 to 14 V


HINT:

The rear speed sensor rotor RH and rear speed sensor RH are incorporated into the rear axle hub and bearing assembly RH.

If the rear speed sensor rotor RH and rear speed sensor RH need to be replaced, replace them together with the rear axle hub and bearing assembly RH.
