This kit is intended to provide the necessary components to replace

™

a Bendix

Gen. 4

ABS ECU (part number 300126) with a Bendix

™

Gen. 5

ABS ECU (part number 801753 or equivalent).

For many vehicles, the ECU replacement requires only

a changeout of the ECU and a reconﬁ guration step.

For vehicles where the original ECU used the J1922 link

to communicate with the engine retarder control, the

extra steps outlined in the "Retarder Relay Installation"

section will also need to be carried out.

Read and follow all standard safety guidelines, including

those found in the General Maintenance Precautions

section on page 2 of this document.

The replacement controller is a Gen. 5

not support J1922 engine communications, so, as mentioned

above, for installations which use J1922, please also follow

the Section "Retarder Relay Installation." To determine if

the vehicle is using J1922, verify if pins 1 and 3 on the X1

connector are being used, or connect the vehicle to a PC

computer and use the Bendix

look for "Retarder Control" on the ECU Status or Conﬁ guration

screens. Bendix
