CALIBRATION UPGRADE FOR 2009
TOURING MODELS WITH ABS
Purpose
Since Harley-Davidson is committed to continuous improvement,
an ABS (Anti-Lock Brake System) calibration change
was recently incorporated into 2010 ABS equipped Touring
model motorcycles on the production line. These changes
can be applied to 2009 Touring model motorcycles as well.
The refinement to the ABS calibration reduces the likelihood
of unintended ABS activations when braking over bumps,
cracks, and other road surface anomalies in otherwise good
traction conditions. The change also reduces the likelihood of
unintended ABS activation during threshold braking. It also
permits reuse of the Hydraulic Control Unit (HCU) if Electrical
Control Unit (ECU) replacement is required.
In the interest of promoting customer satisfaction, Harley-
Davidson has decided to offer this change as a current production
ABS calibration upgrade at no charge to all owners of
2009 Touring model motorcycles. This offer includes stock
production, Police and CVO motorcycles. This calibration
upgrade offer is valid from now to the end of the motorcycle’s
warranty period.
Motorcycles Affected
All 2009 model year Touring model motorcycles equipped
with ABS.
Required Dealer Action
If customer expresses concern with ABS performance, proceed
with the following steps prior to performing other diagnosis:
1. Connect Digital Technician to the vehicle. If the displayed
ECU calibration is 32836-09, then the ECU
should be reflashed to the 32836-09A calibration.
NOTES
● If the brake system has not been opened since factory
installation or a recent ABS Service has been performed
and it is apparent that there is no air in the hydraulic system,
it is not necessary to perform the "Manual Bleed"
procedures within the ABS Service Procedure after
recalibration. You must follow all other steps which check
for proper brake operation and clear the C1158 code.
● A proper "Manual Brake Bleed" procedure must be performed
at each appropriate step of the ABS Service if
the brake lines have been opened for any reason.
2. Complete ABS Service within Digital Technician after
performing reflash.
Credit Procedure
NOTE
Warranty coverage for calibration updates ends with
