Honda HR-V: Testing

POWER RELAY TEST

Special Tools Required

Relay Puller 07AAC- 000A2A1 or 07AAC- 000A1A0

Relay Socket Extension (5 Pin) 07AGK- 000A2A0

Relay Socket Extension (4 Pin) 07AGK- 000A1A0

Test

1. Power Relay - Test

Use this chart to identify the types of the relay, then do the test listed for it.

*: Carefully remove the relay using the special relay puller tool. Do not use pliers. Pliers will damage the relay.

Normally-Open Four-Terminal Type

Check for continuity between the terminals:

• There should be continuity between terminals No. 1 and No. 2 when 12 volt battery power is connected to terminal No. 3, and 12 volt battery ground is connected to terminal No. 4.
• There should be no continuity between terminals No. 1 and No. 2 when 12 volt battery power is disconnected.

Five-Terminal Type

Check for continuity between the terminals:

• There should be continuity between terminals No. 1 and No. 2 when 12 volt battery power is connected to terminal No. 3, and 12 volt battery ground is connected to terminal No. 5.
• There should be continuity between terminals No. 1 and No. 4 when 12 volt battery power is disconnected.

RADIATOR CAP TEST

Test

1. Radiator Cap - Test

1. Wait until the engine is cool, then carefully remove the radiator cap (A). Wet the radiator cap seal with engine coolant, then install it on a commercially available pressure tester (B)
2. Apply a pressure of 93-123 kPa (0.95-1.25 kgf/cm2, 13.5-17.8 psi)
3. Check for a drop in pressure
4. If the pressure drops, replace the radiator cap.

RADIATOR TEST

Test

1. Radiator -Test

1. Wait until the engine is cool, then carefully remove the radiator cap, and fill the radiator with engine coolant to the base of the filler neck
2. Attach a commercially available pressure tester (A) to the radiator, and apply a pressure of 93-123 kPa (0.95-1.25 kgf/cm 2, 13.5-17.8 psi)
3. Inspect for engine coolant leaks and a drop in pressure
4. Remove the pressure tester, then reinstall the radiator cap.

RADIATOR AND A/C CONDENSER FAN MOTOR TEST

Test

1. Fan Motor - Test

1. Disconnect the connectors from the radiator fan motor (A) and the A/C condenser fan motor (B).
2. Test each motor by connecting 12 volt battery power to terminal No. 1 and ground to terminal No. 2.
3. If a motor fails to run or does not run smoothly, replace it.
