Diagnostic Fault Information
1. Turn Signal Lamps and/or Indicators Malfunction
2. Turn Signal/Multifunction Switch Malfunction
3. Turn Signal Lamp Outage Detection Malfunction
Circuit/System Description
Ground is applied at all times to the turn signal/multifunction switch. The
turn signal lamps may only be
activated with the ignition switch in the ON or START positions. When the turn
signal/multifunction
switch is placed in either the TURN RIGHT or TURN LEFT position, ground is
applied to the body
control module (BCM) through either the right turn or left turn signal switch
signal circuit. The BCM
responds to the turn signal switch input by applying a pulsating voltage to the
front and rear turn signal
lamps through there respective control circuits. When a turn signal request is
received by the BCM, a
serial data message is sent to the instrument cluster requesting the respective
turn signal indicator be
pulsed ON and OFF.
Diagnostic Aids
When replacing a headlamp assembly, the following control modules located on
each headlamp
assembly are serviceable.
- K189L Headlamp/Cornering Lamp Control Module - Left
