CUSTOMER SATISFACTION CAMPAIGN 2A91
GSX-R1000RA/RZAL7-L8 Inertial Sensor Replacement
Affected Models:

2017 - 2018 GSX-R1000R/RZ

Affected Departments:

Management, Service, Warranty, Sales, Parts, Accessories

Suzuki Motor of America, Inc. (Suzuki) is initiating a customer satisfaction campaign to replace the inertial sensor
on certain 2017 - 2018 GSX-R1000R/RZ motorcycles.
It has been determined that when low battery voltage is present in the motorcycle (due to long term storage, normal
depletion, etc.), a communication error between the anti-lock brake system (ABS) and inertial sensor (also known as
an inertial measurement unit) will cause the ABS warning lamp to illuminate while disabling the ABS.

Verify the motorcycle is affected as instructed above.

2)

Use the Suzuki Diagnostic System II (SDS-II) tool to inspect the motorcycle for diagnostic trouble codes
(DTCs) as instructed in the repair procedure of this Technical Service Bulletin, and replace the inertial
sensor with the countermeasure part.
