Removal |
|
1. |
Shut off the High Voltage circuit. (Refer to Hybrid Control System - “High Voltage Shutoff Procedure”) |
2. |
Remove the power relay assembly. (Refer to High Voltage Battery System - "Power Relay Assembly (PRA)") |
3. |
Remove the pre-charge relay (A).
|
Inspection |
|
High voltage pre-charge relay switch resistance |
[Use multi-tester (relay OFF)]
This is the inspection procedure by using a multi tester while the high voltage (-) relay is OFF. |
1. |
Shut off the high voltage circuit. (Refer to Hybrid Control System - “High Voltage Shutoff Procedure”) |
2. |
Remove the rear seat cushion. (Refer to Body - "Rear Seat Assembly") |
3. |
Remove the rear door scuff trim. (Refer to Body - "Door Scuff Trim") |
4. |
Remove the inlet cooling duct. (Refer to High Voltage Battery Cooling System - "Cooling Duct") |
5. |
Measure the resistance between the high voltage power terminal (+) and the inverter power terminal (+).
|
6. |
If the measured resistance is not within the specification, replace the main relay (-) by referring to repair procedures. |
[KDS/GDS - relay ON]
1. |
Connect the KDS/GDS to the Data Link Connector (DLC). |
2. |
Switch "ON" the ignition. |
3. |
Activate the pre-charge relay by selecting "Actuation Test" on the KDS/GDS as shown in the illustration below.
|
High Voltage Per-Charge Relay Coil Resistance |
1. |
Shut off the high voltage. (Refer to "High Voltage Shut-off Procedures") |
2. |
Remove the power relay assembly. (High Battery System - "Power Relay Assembly") |
3. |
Check for continuity between the terminals using an ohmmeter.
|
Installation |
|
1. |
Install the main relay in the reverse order of removal. |
