No the grips were existing and we're not removed.
I did put about 60 miles on her today and the light has not came back on. I didn't check to see if there was any codes either so i don't know if it was a fluke or if it's been a problem and just never threw a light.
This code checks the rear audio switch. There are two rear audio switches, an AUDIO/PTT and MODE switch. Both are located on the rear right speaker pod. These buttons are connected to the radio with one signal wire connection.
DTCs B1306 and B1307 are monitored continuously by the radio on B2 of [27]. (Check out image I provided). If the signal wire is shorted high or low, it will immediately set a DTC.
From the Touring Diagnostics: Audio System....
Table 8-21. DTC B1306 Diagnostic Faults
POSSIBLE CAUSES
Damaged rear audio switch
Reset needed
However, since you don't have rear audio, it's probably what we would call a stray signal from somewhere. You can probably just reset it and forget about it. IF you had rear audio, here are the steps to further diagnose it....
1. Voltage Test
1. Turn IGN OFF.
2. Connect BREAKOUT BOX (Part No. HD-50390-1) and
BCM CABLE (Part No. HD-50390-2) to wiring harness
[27B] and radio [27A]. See 1.4 DIAGNOSTIC TOOLS.
3. Verify BCM OVERLAY (Part No. HD-50390-2-P) is in
position on BOB.
4. Turn IGN ON.
5. Test voltage between BOB terminal B2 and ground.
6. Is voltage greater than 5.0V?
a. Yes. Go to Test 2.
b. No. Go to Test 3.
2. Rear Audio Test
1. Disconnect rear audio [162].
2. Test voltage between BOB terminal B2 and ground.
3. Is voltage greater than 6.0V?
a. Yes. Repair short between [27B] terminal B2 and
[162A] terminal 15 (LBE/BK).
b. No. Replace rear audio switch.
3. Reset Test
1. Perform a pre-calibration reset. See 8.1 AUDIO SPECIFICATIONS
AND SERVICE FUNCTIONS.
2. Turn IGN OFF.
3. Turn IGN ON. Allow radio to start playing. Wait 30 seconds
and turn IGN OFF.
4. Check DTCs.
5. Did DTC reset?
a. Yes. Replace radio.
b. No. System working properly.
