General Motors service tips are intended

for use by professional technicians, not

a “do-it-yourselfer.” T hey are written to

inform those technicians of conditions

that may occur on some vehicles, or to

provide information that could assist in

the proper service of a vehicle. Properly

trained technicians have the equipment,

tools, safety instructions and know-how to

do a job properly and safely. If a condition

is described, do not assume that the

information applies to your vehicle or that

your vehicle will have that condition. See a

General Motors dealer servicing your brand

of General Motors vehicle for information

on whether your vehicle may beneﬁt from

the information.

Inclusion in this publication is not

necessarily an endorsement of the

individual or the company.

A BCM calibration has changed the operation of the hazard switch on 2014 CTS sedan

models produced after October 11, 2013, or any vehicle that has had the BCM pro-

grammed during service. After the calibration update, the hazard switch must be pressed

and held for one second before the hazard ﬂashers will operate.

Advise customers that the hazard ﬂashers may not activate during the ﬁrst press of the

switch if the switch is not held for one second.

Buzzing Noise at Right Front Wheel

Heated/Cooled Seat Operation

during Remote Start

Revised Operation of Hazard Switch

Some 2012-2013 LaCrosse, Regal; 2013

Malibu Eco; and 2014 Impala Eco models

with eAssist (RPO HP6) may have a buzzing

or humming noise heard in the right front at

times, both when turning or driving straight.

The Service Brake Assist message may be

displayed or the ABS MIL or Service Engine

Soon MIL may be illuminated. DTCs C027B

(Brake Booster Electric Vacuum Pump),

C0040 (Right Front Wheel Speed Sensor

Circuit) and P0CBE (Drive Motor Coolant

Temperature Sensor Circuit Low Voltage)

may be set.

This condition may be caused by the underhood wiring harness contacting the crank

pulley, air conditioning compressor pulley or accessory drive belt due to misrouting or not

being secured properly.

Repair the wiring as needed or replace the harness. Properly route and secure the

harness. Once wiring repairs are complete, conﬁrm proper brake booster vacuum pump

operation. The pump can be commanded on using GDS2. Clear all DTCs.

The heated and cooled seats available on the 2014 Silverado 1500 and Sierra 1500 trucks

can be set to turn on during a remote start. The seats will only turn on if the ambient

temperature meets the predetermined threshold.

During a remote start, the heated seats will turn on when ambient temperature is below

50° F (10° C).

During a remote start, the cooled seats will turn on when ambient temperature is above

80° F (27° C).

Use the Vehicle Settings menu to enable the seats to turn on during a remote start.

TIP: The heated or cooled seat indicator lights do not turn on during a remote start and

the temperature performance of an unoccupied seat may be reduced. This is normal.
