RE: Diagnostic plug
George,
I think this schematic shows that the front diagnostic port taps off the datalink at the Allison ECU transmission connector: http://wanderlodgegurus.com/database/Mod...ission.pdf Here's the link to the LXi fuse locations that I tried to post earlier: http://wanderlodgegurus.com/database/ind...F1998-2003 The datalink starts at the DDEC ECU wiring harness (HC2) and connects to the Frame wiring harness (HC1) at P22/P24. It then connects to the Allison ECU at the Frame wiring harness (HC1) at P24/P4, at which point the diagnostic port taps off. The following diagram shows the DDEC ECU connecting to frame components (HC1 wiring harness) at connector P22. The DDEC ECM connects at P1. http://wanderlodgegurus.com/database/Mod...arning.pdf The following diagram shows the Allison ECU connected to 'frame components (HC1 wiring harness) via connectors P24/P4 and to the engine DDEC (HC1 wiring harness) at P22/P22. http://wanderlodgegurus.com/database/Mod...onnect.pdf The following diagram shows the datalink connecting from the 'engine interconnect' connector P22 to the Allison ECU at P24 along the Frame Wiring Harness (HC1). http://wanderlodgegurus.com/database/Mod...onents.pdf david brady, '02 Wanderlodge LXi 'Smokey' (Sold), '04 Prevost H3 Vantare 'SpongeBob' "I don't like being wrong, but I really hate being right" |
