  • This navigation DTC sets when a problem (open or short) is detected in the GA-Net BUS (the XM icon is red in the System Links).
  • Before you troubleshoot, make sure to follow the General Troubleshooting Information.
  • Check any official Honda service website for more service information about the navigation system.
  • Check the connectors for poor connections or loose terminals.

1. Problem verification:

  1. Clear the hard error codes.
  2. Turn the vehicle to the OFF (LOCK) mode then the ON mode.
  3. Check for hard error codes.

Is DTC 2607 indicated?

YES

The failure is duplicated, go to step 2.

NO

Intermittent failure, the system is OK at this time.

2. Determine possible failure area (GA+B line, others):

  1. Turn the vehicle to the OFF (LOCK) mode.
  2. Disconnect the following connector.

XM receiver connector A (14P)

  1. Measure the voltage between test points 1 and 2.

Audio-Navigation System - Diagnostics

Is there battery voltage?

YES

Go to step 5.

NO

Go to step 3.

3. Open wire check (GA+B line)

  1. Measure the voltage between test points 1 and 2.

Audio-Navigation System - Diagnostics

Is there battery voltage?

YES

Repair an open in the wire between the audio-navigation unit and the XM receiver.

NO

The GA+B wire is not open. Go to step 4.

4. Shorted wire check (GA+B line):

  1. Disconnect the following connector.

NO

Replace the audio-navigation unit.

5. Determine possible failure area (GA GND line, others):

  1. Reconnect XM receiver connector A (14P).
  2. Turn the vehicle to the ON mode.
  3. Measure the voltage between test points 1 and 2.

Audio-Navigation System - Diagnostics

Is there less than 0.2 V?

YES

Go to step 7.

NO

Go to step 6.

6. Open wire check (GA GND line):

  1. Turn the vehicle to the OFF (LOCK) mode.
  2. Measure the voltage between test points 1 and 2.

Audio-Navigation System - Diagnostics

Is there any voltage?

YES

Replace the audio-navigation unit.

NO

Repair an open or high resistance in the wire between the audio-navigation unit and the XM receiver.

7. Determine possible failure area (GA SYS ON line, others):

  1. Turn the vehicle to the OFF (LOCK) mode.
  2. Measure the voltage between test points 1 and 2.

Audio-Navigation System - Diagnostics

Is there battery voltage?

YES

Go to step 9.

NO

Go to step 8.

8. Open wire check (GA SYS ON line):

Measure the voltage between test points 1 and 2.

Audio-Navigation System - Diagnostics

Is there battery voltage?

YES

Repair an open in the wire between the audio-navigation unit and the XM receiver.

NO

Replace the XM receiver.

9. Audio-navigation unit check:

  1. Turn the vehicle to the ON mode.
  2. Measure the voltage between test points 1 and 2.

Audio-Navigation System - Diagnostics

Is there less than 0.2 V?

YES

Go to step 10.

NO

Replace the audio-navigation unit.

10.Shorted wire check (GA BUS+, GA BUS- lines):

  1. Turn the vehicle to the OFF (LOCK) mode.
  2. Disconnect the following connectors.

Audio-navigation unit connector D (12P)

XM receiver connector A (14P)

  1. Check for continuity between test points 1 and 2.

Audio-Navigation System - Diagnostics

Is there continuity?

YES

There is a short to body ground in the wire(s) between the audio-navigation unit and the XM receiver.

Replace the affected shielded harness.

NO

The GA BUS+ and the GA BUS- wires are not shorted to ground. Go to step 11.

11.Shorted wire check (GA BUS+ line to GA BUS- line):

Check for continuity between test points 1 and 2.

Audio-Navigation System - Diagnostics

Is there continuity?

YES

There is a short in the wires between the audio-navigation unit and the XM receiver. Replace the affected shielded harness.

NO

The GA BUS+ and the GA BUS- wires are not shorted. Go to step 12.

12.Shorted wire check (SH GA BUS line to another lines):

Check for continuity between test points 1 and 2.

Audio-Navigation System - Diagnostics

Is there continuity?

YES

There is a short in the wires between the audio-navigation unit and the XM receiver. Replace the affected shielded harness.

NO

The SH GA BUS wire is OK. Go to step 13.

13.Open wire check (GA BUS+, GA BUS- lines):

Check for continuity between test points 1 and 2.

Audio-Navigation System - Diagnostics

Is there continuity?

YES

Replace the XM receiver.

NO

There is an open in the wire(s) between the audio-navigation unit and the XM receiver. Replace the affected shielded harness.
