Steering Column Cover removal

<< < (5/5)

Steve Huber:
Roger,
Your coach is apparently a late year model as the 08 connector tables show the VCE-1 to HR1-30 connection that the 07 tables don't. But the 08 wiring diagrams don't. (Thx Monaco!). In any case F69 should be between pin 30 of the headlight relay R11 and the common pin of the dimmer switch (one controlled by the stalk on the steering column). Since F69 blows when you select low beam with the dimmer switch, the problem is between the low beam switch connection and the headlights. You stated the original DRLM connector is just hanging and not connected. I would disconnect the replacement connector to see of that resolves the F69 issue. Removal of the DRLM should not impact the headlight functions.
If F69 still blows I would start by unplugging the headlight connectors at the headlights and verify the fuse still blows when low beam is selected. If not the problem is at the headlights. If it does blow, leave the headlights disconnected and verify the wiring from VCB-11 to VCC-2 to the headlight connector. If no short is found the only other possible source is the VCB-11 to NAV-9 (GPS connector, pin 9). It's a 9 pin connector that should be in the front bay. Disconnect it to see if that solves the fuse blowing issue.
As far as the DRLM, as I noted its not needed for the headlights to work. If the original (factory) connector is disconnected, you may want to reconnect it. But fix the fuse issue first.

OK Steve that sounds good yeah unfortunately I won’t be able to get to that till next week.
Just for clarification this DRLM module isn’t something that I think is in the forward bay as I previously stated in a post the PO has put in aftermarket headlight units that are not the originals I do have them disconnected from the wiring harness to eliminate any potential issues they might be causing.
I will definitely have to do a little bit more investigation on this other option you stated regarding where the F 69 fuse goes to this GPS pin.

Steve Huber:
Roger,
The wiring diagram indicates the DLRM module is part of the Front Cap harness, indicating it in the front cap or possible in the front elec bay. I would find it and disconnect it before any other troubleshooting since the PO added/modified it.
Steve

Roger Milne:
Ok thanks. I’ll see what I can find out regarding that and eliminate it from the equation.
