So, that means that "The reference is short-circuited to GND". Here are guidelines from the manual (note, that it is US version of TOD, but I think they are mostly the same, though the pins could be different):

2001 Isuzu VehiCROSS (build in progress): 4JX1/A340/part time, 2" body lift, front Aisin hubs, rear Aussie Locker, 4.56 gears, OEM rear sway bar disconnect, AirFlow snorkel, cabin air filter
1980 Jeep Cherokee (assembling): 1.5" body lift, TBI, HEI
1987 AMC Eagle: stock
