APPLICABILITY

1985 & 1986 STATION WAGON AND SEDAN VEHICLES

WITH ACCESSORY CRUISE CONTROL DATE 01-17-86

SUBJECT: PRODUCT IMPROVEMENTS/MODIFICATIONS

NOTE: THIS SERVICE BULLETIN IS FOR INFORMATION ONLY

Listed below are several product improvement/modifications that have taken effect which are designed to ease Accessory Cruise Control installation in 1986 vehicles. All improvements/modifications will be effective in all Cruise Control kits with a packing date of 12-9-85 or later.


The flange nut used for revolution sensor relocation on 1986 4WD Station Wagon and Sedan Non-ECC vehicles will be included in all applicable Cruise Control kits. Applicable Cruise Control kits include SOA 386C100 (all automatic transmission vehicles) and SOA 386C101 (4WD manual transmission vehicles). Revolution sensor relocation was covered in Subaru Service Bulletin Number 15-28-85 dated 12-11-85.


The master wire harness for automatic transmission vehicles has been modified with a bullet connector on the neutral inhibitor wire. This will allow for either a two pin or three pin wire harness adapter to be plugged into depending upon the application. The part number for the master wire harness is changed from SOA 386C317 to SOA 386C332 to reflect this modification. A two pin wire harness adapter is to be used on SPI equipped (FWD) vehicles and carries part number SOA 386C334. A three pin wire harness adapter is to be used on carbureted (4WD) vehicles and carries part number SOA 386C333. Both wiring adapters are included in Cruise Control Kit SOA 386C100 (all automatic transmission vehicles). Since only one wiring adapter is needed per installation, the remaining wiring adapter can be discarded. This product improvement eliminates the need to use a scotchlock connector when connecting the cruise control wiring harness to SPI equipped vehicles' neutral inhibitor wiring.

FIGURE 1:

Both master wiring harnesses (SOA 386C322 automatic transmission and SOA 386C324 manual transmission), will also reflect the product improvement shown in Figure 1 (next page). The purpose of this modification is to improve the flexibility of the wire harness at the electronic module multi-pin connector. The wire harness makes a sharp bend in its installed position to reach the electronic module. Depending upon installation, the stiffness and routing of the older style wire harness in this area could create enough pressure on the connector to cause it to distort away from the multi-pin circuit board. This may cause erratic performance symptoms. Should this condition be suspect, the removal of 2" to 2-1/2" of insulating tape will allow for added flexibility.
This modification is only required on older style wiring harnesses and should be properly re-bound at the end of the unwrapped area with electrical tape. Before replacing an electronic module, a check of the wire bundle at the electronic module area should be performed.
