Scheme 125

Cable Stripping

Proper wire stripping and connector replacement is essential to ensure the integrity of the electrical connection. Always follow specific instructions in the Electrical Repair Kit IV instruction manual.

The length of wire to be stripped is determined by the wire gauge.

WIRE CROSS-SECTION SIZE SPECIFICATIONS

Scheme 126

Proper use of the wire stripping tool will provide consistently positive results. Insert the wire (1) into the stripper. Stop the wire when the required strip length is past the cutter (2). Squeeze the handle of the tool.

Scheme 127

When the top jaw of the tool touches the wire (3) the mechanism shifts the clamping action to a pulling action which strips the wire of the insulation (4).

Scheme 128

Crimping

Use the wire crimper from the BMW Electrical Repair Kit. This crimper is designed for the specific connectors found in BMW automobiles. Proper use of the tools will provide consistent good quality connector crimps.

The crimper is designed to apply just the right amount of pressure based on the wire gauge and connector size.

Scheme 129

The tool has removable crimper jaws (3). This feature allows for an unlimited number of connector types for future compatibility. The article refers to the different sized crimping slots as "Nests". The gauge of the wire being crimped determines which "Nest" is used.

Scheme 130

WIRE CROSS-SECTION SIZE SPECIFICATIONS

Example

A. 75 - 1.0mm gauge wire requires nest 2 for proper crimping.

Throughout the Electrical Repair Kit instruction manual are illustrations of various connectors being crimped. The highlighted box of the 16 box grid in these illustrations refers to the storage compartment in the electrical kit drawers in which that specific connector can be found.

Insert the "crimping end" of the connector into the appropriate "nest". Illustration provides example of comb replacement connector (4) and inline splice connector (5).

Scheme 131

Squeeze the tool handle slightly to set the tool in the first ratchet latch position. This will hold the connector in the tool without closing the crimp (6).

Insert the stripped wire into the receiving end of the crimper tool making sure the wire is inserted far enough to ensure that only the wire insulation will be inside the insulation support barrel (7).

Properly crimped connectors exhibit the following characteristics

Scheme 132

1. The insulation support barrel will be crimped consistently and snug against the insulation. The insulation will not be crushed (8).
2. A bellmouth crimp will be visible at the wire end of the of the wire barrel (9).
3. Wire strands will be visible at the contact end of the wire barrel (10).
4. Insulation end will be visible in this area (11) (Scheme 134)

Scheme 133

The following are examples of unacceptable crimps: (Scheme 135)

1. Excessive or no wire strands at the contact end of the wire barrel (10).
2. Excessive or no insulation end in the acceptable area (11).

Scheme 134

Scheme 135

Prepackaged Wiring Repair Sets

Included with the Electrical Repair Kit IV are a variety of wiring repair sets. These sets contain various pre-crimped wiring connectors on assorted gauge wire lengths for simple splice connection repair into a wiring harness.

The repair kits also contain

1. Various gauge lengths of wire with precrimped connectors.
2. In-line splice connectors.
3. Heat shrink tubing.

Scheme 136

When used correctly the in-line splice connectors provide a BMW factory approved wire crimp. Use the correct size nest in the crimper tool and connect one side of the in-line crimp with the wire.

Slide a piece of heat shrink tubing on the wire and crimp the other side of the in-line connector.

Scheme 137

Use a heat gun to shrink the tube around the splice connector to provide a moisture resistant seal.

Part numbers for the wire sets or any component of all four electrical repair kits can be reordered from

1. The P/N reference card inside each repair kit.
2. Special tools microfiche.
3. The Electrical Repair Kit 1-4 component catalog (SD 92-036).

Scheme 138

As new connectors are developed for new vehicles, the repair kits will be added to appropriate articles.

Soldering Connections

In the event that a wiring connection must be soldered in a vehicle's electrical system, there are certain procedures which must be followed. Improper soldering will result in poor electrical connections or damage to electrical components.

SAFETY: Adhere to the following basic guidelines when preparing to solder.

1. Safety glasses must be worn.
2. Disconnect vehicle battery.
3. Cover vehicle trim surfaces.
4. Exercise your common sense.
5. Provide adequate ventilation, it's the best safety precaution!

Scheme 139

Soldering Preparation and Procedure

1. The wire insulation must be stripped to expose an adequate amount of bare wire (not too little-not to much.)
2. The wires and or connectors must be clean and free of grease, dirt, wax, etc.
3. A thin coating of rosin core flux must be applied to the soldering connection.
4. Have enough 60/40 (tin/lead) general electrical solder on hand prior to starting.
5. If heat transfer to a heat sensitive component is possible use "heat sinks".
6. Use a soldering gun tip that is the right size for the job. Do not use an overly large tip which could melt wire insulation and block your view of what is being soldered.
7. The soldering tip must be "tinned" . This means to keep a thin layer of solder on the tip at all times during soldering. This will transfer the heat quickly and allow the solder to flow easily into the joint being soldered.
8. Preheat the wires or connector. Introduce the solder into the joint not the soldering tip.
9. When the solder starts to flow allow it to infiltrate the joint only for a moment. Almost simultaneously, pull the tip off of the joint to prevent overheating.
10. A properly soldered joint will be smooth, shinny, and even surfaced.

Scheme 140

Breakout Boxes and "V" Cables

Breakout Boxes are used to

1. Provide a convenient "tap" into an electrical circuit.
2. Minimize the possibility of damage to control unit connections and wire harnesses during diagnosis of electrical/electronic systems.
3. Ensure solid meter connections for proper diagnosis, this in turn will help the technician to be more organized and efficient.
4. Provide easier access to circuits for testing with equipment such as, multimeter, DISplus tester or other diagnostic tools.

Example: DME and EGS/AGS control modules both utilize an 88 or 134 pin control module. These control modules reside in the same E-Box on most vehicles. The control modules are coded to prevent unintentional cross connecting at the vehicle harness. But, this connector coding is not present on the 88 or 134 pin breakout box(s). Result: A DME control module could be connected to a transmission control system. Damage will result!

Several different types of breakout boxes are available depending on the particular system being diagnosed.

Scheme 141

55 pin Breakout Box P/N 81 12 9 425 091

Used with control modules that have single multipin plugs from 25 to 55 pins.

1. L-jetronic.
2. ABS.

Scheme 144

134 Pin SKE Control Module Breakout Box Set P/N 90 88 6 121 300

The 134 pin modular connector DME and AGS control modules use a combination of breakout boxes for troubleshooting. The part number above provides three breakout boxes and five adapter harnesses. The two outside edge connectors use the familiar 26 pin breakout boxes. The three inside connectors use the boxes from the ordered set.

Scheme 145

26 Pin Breakout Box P/n 88 88 6 611 459

Used with system or peripheral control module that have up to 26 pins. This breakout box is used in conjunction with adapter cables called "V" Cables. There are many different types of "V" cables for the various connectors found on the vehicles.

Scheme 146

Used for connecting all adapter leads with 27 pin to 60 pin plug connections.

Scheme 147

Tester and Adapter Set for Relays

The Relay Adapter provides a platform to test a relay while allowing the relay to remain active in a circuit.

The adapters included enable different pin configurations of relays to be tested using a single tester.

Scheme 148

Remove relay and compare plug in adapter with plug pattern on relay. Choose correct adapter (Scheme 149)

Fit adapter to Measuring bridge, noting the marker arrows (A). Fit the relay to the measuring bridge (Scheme 150)

Plug the assemble measuring bridge into the socket of the relay to be checked. Test using a multimeter. See the circuit diagram, testing instructions in the appropriate article for subsequent procedure (Scheme 151)

Scheme 149

Scheme 150

Scheme 151

"V" Cables

"V" cables are available in different versions depending on the system being diagnosed. Always refer to the most recent information for the required special tools.

"V" cables are only used with the 26 pin breakout box to access input and output signals of peripheral modules and systems.

Scheme 152

1. The appropriate cable is distinguished by the color of the connector end.
2. The color will match the particular modules connector color. Unless the color matches, the cable will not fit the connector on the module being tested.
3. Each colored "V" cable has a series of alignment tabs that will only fit it's particular module or system.

"V" cables with ELO connectors are also being used with the 26 pin breakout box. These cables are unique in that they have a locking arm on the component side of the cable. They are light green in color, and the number of pins will vary depending on the system being tested.

"V" harness adapters were introduced with the E38. These also have light green ELO connectors on the component side, but they do not require a breakout box.

There is a black plug on one side with same number of pins as the component being tested.

The plug has numbers stamped on it's side that corresponds with the pins on that particular component.

You access the signals by plugging the test equipment directly into those pin numbers.

As new systems and components are being introduced, new breakout boxes and cables will also be introduced.
