Honda HR-V: Power Mirror Function Test

1. Disconnect the following connector.

Power mirror switch 13P connector

2. Choose the appropriate test based on the symptom:

• Both mirrors do not work, go to step 3.
• Left mirror does not work, go to step 5.
• Right mirror does not work, go to step 6.
• Mirror defogger (With power mirror defogger) does not work, go to step 7.

Both Mirrors

3. Measure the voltage between terminal No. 4 and body ground with vehicle to ON mode. There should be battery voltage.

• If there is no battery voltage, check for:
  • Blown No. C24 (7.5 A) fuse in the under-dash fuse/relay box.
  • An open in the PNK wire.
• If there is battery voltage, go to step 4.

4. Check for continuity between terminal No. 13 and body ground. There should be continuity.

• If there is no continuity, check for:
  • An open in the BLK wire.
  • Poor ground (G401).
• If there is continuity, go to step 5.

Left Mirror

5. Connect terminals No. 4 and No. 9, and terminals No. 1 (or No. 7) and No. 13 with jumper wires, and vehicle to ON mode. The left mirror should tilt down (or swing left).

• If the left mirror does not tilt down (or does not swing left), check for an open or high resistance in the TAN (or GRY) wire between the left mirror and the 13P connector. If the wire is OK, check the left mirror actuator.
• If the mirror neither tilts down nor swings left, repair the PUR wire.
• If the mirror works properly, check the power mirror switch.

Right Mirror

6. Connect terminals No. 4 and No. 8, and terminals No. 1 (or No. 6) and No. 13 with jumper wires, and vehicle to ON mode.The right mirror should tilt down (or swing left).

• If the right mirror does not tilt down (or does not swing left), check for an open or high resistance in the TAN (or BLU) wire between the right mirror and the 13P connector. If the wire is OK, check the right mirror actuator.
• If the mirror neither tilts down nor swings left, repair the WHT wire.
• If the mirror works properly, check the power mirror switch.

Mirror Defogger (With power mirror defogger)

7. Connect rear window defogger relay terminals No. 1 and No. 2 with a jumper wire. Measure the voltage between terminal No. 7 of the mirror connectors and body ground. There should be battery voltage and both mirrors should warm up.

• If there is no voltage or neither warms up, check for:
  • An open or high resistance in the TAN wire.
  • Blown No. D2-1 (30 A) or No. D13 (10 A) fuse in the auxiliary under-dash fuse box A.
• If only one fails to warm up, check:
  • Its defogger.
  • Poor ground (G401, G403).
• If both warm up, check the defogger switch or the rear window defogger relay.
