J-35592 PINOUT BOX
In order to prevent damage to the 35-pin Electronic Brake Control Module (EBCM) connector, J-35592 pinout box should be installed on the EBCM connector prior to probing any circuit with the digital multimeter. This pinout box is to be used combined with J-35616 connector test adapter kit.

IMPORTANT: Do not probe the 35-pin EBCM connector without installing J-35592 pinout box. Damage to connector terminals may occur if the pinout box is not installed, resulting in improper system operation. The following procedure should be used to install J-35592 pinout box.

1. Ignition must be "OFF" when installing or removing the 35-pin EBCM connector.
2. Disconnect the 35-pin EBCM harness connector by depressing the connector locking plate and rotating the connector toward the front of vehicle.
3. Inspect the 35-pin connector for damage. Connect J-35592 to the 35-pin connector.
4. Proceed with test as outlined in the diagnostic procedure.
