Introduction
The problem that is identified below does not have a known permanent solution. Until a permanent solution is known, use the solution that is identified below.Problem
VIMS ABL2M platform software provides a sinking output for the operator cab instrument cluster back lighting. The latest 10.6 release software is causing the backlight to be inoperative.Solution
Caterpillar is aware of the problem, but a permanent correction action has not been identified. In the interim, to regain dash light functions, extract pin J1-63 from the ABL2M ECM. Extract pin J1-2 (ABL ground) and apply a Y splice tying J1-63 and J1-2 together. Re-install the remining end of the Y splice back into J1-2.
