Correction
When diagnosing an intermittent electrical concern terminal tension is one of the main culprits, especially when
working with very small terminals. More and more modules and inline connectors are using small .64 series
terminals also more modules are beginning to use the Mini 50 series terminals. When checking terminal tension, it
is important to use the correct test probe. The J-35616-64B is the latest test probe released for checking tension or
probing the .64 series terminals. Also, the EL-35616-58 is the latest test probe released for checking terminal
tension on the Mini .50 series terminals. See pics below.
When testing for proper terminal tension, it's crucial to understand the feel of the terminal tension in comparison to
the terminal being tested. Pay close attention to the point at which the terminal test probe begins to experience drag
or tension during insertion and removal from the terminal. This sensation should be compared to that of similar
terminals within the same connector to ensure consistency and proper tension across all terminals.
Note: Always refer to the Connector End View in Service Information for the latest information on determining the
correct test probe to use.
Information on 64 series terminals
If the terminal end of the J-35616-64B is bent, damaged, worn or broken, it should not be used and a replacement
test probe or terminal should be obtained from GM Tools at 1-844-742-8471. The test probe terminal has been
released in the terminal repair kit (J-38125-620H) located in Lear Tray 7 part number 963716-2 shown below. (Note:
When calling GM Tools to order terminal 963716-2, the actual part number is 963716-2PKG since they are only sold
as a pack) This terminal may also be used to make jumper wires; example: to jumper the High Speed LAN circuits
together in order to bypass a module for testing only. Use crimping tool J-38125-641 and jaw "H" for 22ga wire, "J"
for 20 ga wire, or "K" for 18 ga.
If you cannot locate the Terminals in your terminal kit "Tray 7" your kit is not up to date, and GM tools will need to be
contacted so your kit can be updated.
Another option is to order the .64 test probe terminal already connected to a lead/wire called a terminated lead. The
GM part number is 13505346, which can be ordered through your normal GM CCA parts channel. There are 5
terminated leads in a package, shown below. With the addition of this new terminated lead, there are now 3 different
options for obtaining the proper .64 test probe/terminal:
1. .64 Test Probe - J-35616-64B (ordered from GM Tools at 1-844-742-8471)
2. .64 Replacement Terminal - Lear Tray 7 part number 963716-2 (ordered from GM Tools at 1-844-742-8471)
3. .64 Terminated Lead - GM part number 13505346 (ordered from GM CCA parts)

Information on 50 series terminals
If the terminal end of the EL-35616-58 is bent, damaged, worn or broken, it will need to be replaced as there are no
male terminals available at this time (order from GM Tools at 1-844-742-8471).
No male terminals are available as these terminals are currently used for module connections only.
Replacement female terminals are available for harness side repairs.
See SI connector end views for proper terminal application.

Warranty Information
For wiring repairs covered under warranty, please refer to latest version of bulletin 10-00-89-005 for warranty information on wire/connector repairs.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these
technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper
service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job
properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your
vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the
information.
