Electrical Compass Unit Input Test
WARNING: This page is about a different car, the 2013 Acura MDX, 2012 Acura MDX, 2011 Acura MDX, and 2010 Acura MDX. However, it is still accessible from the selected car via links, so may be relevant.
- Remove the headliner (see HEADLINER REMOVAL/INSTALLATION ).
- Disconnect the 6P connector (A) from the electrical compass unit (B).
- Inspect the connector and socket terminals to be sure they are all making good contact.
- If the terminals are bent, loose, or corroded, repair them as necessary, and recheck the system.
- If the terminals look OK, go to step 4.
- Reconnect the connector to the electrical compass unit, turn the ignition switch to ON (II), and do the following input tests:
- If any test indicates a problem, find and correct the cause, then recheck the system.
- If all input tests prove OK, the electrical compass unit must be faulty; replace it.
| Cavity | Wire | Test Condition | Test: Desired result | Possible cause if desired result is not obtained |
|---|---|---|---|---|
| 2 | BLK | In all ignition switch positions | Measure the voltage to ground: There should be less than 0.2 V. |
|
| 1 | YEL | Ignition switch ON (II) | Measure the voltage to ground: There should be battery voltage. |
|
| 3 | RED | Under all conditions | Measure the voltage to ground: There should be about 4 V. |
|
| 4 | BLU | Under all conditions | Measure the voltage to ground: There should be about 4 V. |
|
| 5 | ORN | Under all conditions | Measure the voltage to ground: There should be about 4 V. |
|
| 6 | GRY | Under all conditions | Measure the voltage to ground: There should be about 4 V. |
