ABS Diagnostic Button?

[ronmc]

Reading on Workhorse forum, I downloaded the manual for the Workhorse ABS system. It states there is a button,near the steering wheel,that controls a diagnostic system for trouble shooting the ABS light staying on. Anyone know more about this button? Can't find it!

ronmc, If you can quote the page in the chassis guide, I'll take a look at it. As far as I know, I don't believe that there is a button.

Displays diagnostic blink codes for
easy servicing.

Blink Code:

A series of blinks or flashes that

describe a particular ABS system condition.
(Refer to

Table D [cab-mounted] or Table E

[frame-mounted] for blink code identification.)
Blink Code Diagnostics:

The ability of the Meritor

WABCO ECU to sense faults in the ABS system
and to define these faults via blink codes.

Blink Code Switch:

A momentary switch that

activates blink code diagnostic capabilities.
Usually, it is mounted under the dash or on the
steering column. Refer to the vehicle
specifications for type and location.

Clearing Fault Codes:

The process of erasing faults

from the ECU memory bank. (Refer to

Table C.)

Fault Code:

An ABS condition (fault) detected and

stored in memory by the Meritor WABCO ECU and
displayed by blink code. System faults may be

Active

or Stored.
Active Fault: A condition

Ron,

I've seen quite a few bare chassis and I don't recall seeing the button that you are describing.

Give Alan a call at Workhorse, he will know where to find it if it's installed

I do find this line interesting "The ability of the Meritor"...

As people keep telling me they don't use Arvin Meritor systems.

John-D, I am not sure where you heard this but let me assure you there are several "thousand" Arvin Meritor braking components on the road right now under a badged Workhorse chassis. The W24 uses an Arvin Meritor Quadraulic 4 piston caliper. Just possibly the "best" hydraulic calipers on the market on a front gas chassis. When used on the UFO with the Arvin Meritor WABCO braking system, the Quadraulic caliper is the best hydraulic caliper on the market on any Class 6 or larger recreational vehicle.
