DIAGNOSTIC PROCEDURE
| Step | Check | Yes | No |
|---|---|---|---|
1 CHECK VDCCM&H/U INPUT VOLTAGE.
|
Is the voltage 10 - 15 V? | Go to step 2 . | Repair the VDCCM&H/U power supply circuit. |
| 2 CHECK INSTALLATION OF MOTOR GROUND. | Is the motor ground terminal installation bolt tightened 33 N.m (3.4 kgf-m, 24.3 ft-lb)? | Go to step 3 . | Tighten the motor ground terminal installation bolt. |
3 CHECK VDCCM&H/U GROUND CIRCUIT.
|
Is the resistance less than 10 Ω? | Go to step 4 . | Repair the VDCCM&H/U ground harness. |
| 4 CHECK VDCCM&H/U MOTOR RELAY. Measure the resistance between VDCCM&H/U terminals. Terminals No. 23 - No. 22: |
Is the resistance 1 MΩ or more? | Go to step 5 . | Replace the VDCCM&H/U. < Refer to VDC CONTROL MODULE AND HYDRAULIC CONTROL UNIT (VDCCM& H/U) . > |
| 5 CHECK POOR CONTACT OF CONNECTORS. Turn the ignition switch to OFF. |
Is there poor contact of connector between generator, battery and VDCCM&H/U? | Repair the connector. | Go to step 6 . |
6 CHECK VDCCM&H/U.
|
Is the same DTC displayed? | Replace the VDCCM&H/U. < Refer to VDC CONTROL MODULE AND HYDRAULIC CONTROL UNIT (VDCCM& H/U) . > | Go to step 7 . |
| 7 CHECK OTHER DTC DETECTION. | Is any other DTC displayed? | Perform the diagnosis according to DTC. < Refer to LIST OF DIAGNOSTIC TROUBLE CODE (DTC) . > | Temporary poor contact occurs.
NOTE:
Though the ABS warning light remains on at this time, this is normal. Drive the vehicle at 12 km/h (7 MPH) or more in order to turn ABS warning light off. Be sure to drive the vehicle and check that the warning light goes off.
