2006 Buick LaCrosse CXS Questions & Answers
Gags not working buick lacrosse 2006 3.6
I can tell you how instrument cluster works, but, I can't diagnose it from here.
The sending unit for any gage sends signal to pcm, the pcm then sends serial data to the instrument cluster to control gages. Some of the gages will default to zero if the pcm detects problem with sending unit or wiring, or the instrument cluster detects a problem with serial data from pcm.
Check for applicable trouble codes, see if codes point in any particular direction. Some of the national brand auto stores will check codes for free, if there are any. You can check voltage and ground for instrument cluster, just to make sure that is ok. I can't rule out the instrument cluster, itself.
What is a p0496 error on a 2006 buick lacrosse cxs
The P0496 DTC code is a generic code which applies to all vehicle makes.
A quick search on the 'net shows that this code seems to be more common
with GM (Chevy, Pontiac, etc.) vehicles. In Acura, Honda, Hyundai, Kia,
and Mazda vehicles, this code is described "EVAP system high purge
flow" which is the same thing.try use
maxiscan us703 to clear the fault code.
2005 Buick lacrosse cxs first highbeams went out then low beams but all other lights work.
Headlamps
You can use the headlamps two different ways.
• Place the headlamp switch in the HEAD position for normal operations
• Place the headlamp switch in the OFF position for automatic lamp control (ALC) operation. During ALC the low beam headlamps are ON for daytime running lamp (DRL) operation in daylight conditions at reduced intensity or low beam headlamps ON at full intensity with exterior park lamps ON in low light conditions.
The body control module (BCM) applies a pulse width modulated (PWM) voltage to the headlamp module and high beam relay in the underhood fuse block. The ground for the headlamp module is supplied from G113 or G115. For normal manual low beam operation when the headlamp switch is place in the HEAD position, ground from G202 is applied through the headlamp switch and to the BCM through the headlamp switch headlamps ON signal circuit. The BCM then applies a PWM voltage to the headlamp module/high beam relay voltage supply circuit. The headlamp module then applies battery positive voltage through the left front (LF) and right front (RF) LO Beam fuses to the left and right low beam headlamps. The ground for the left headlamps is supplied by G101 and the ground for the right headlamp is supplied by G100.
For high beam operation, ground is applied at all times to the headlamp dimmer switch from G202. When the headlamp dimmer switch is placed in the HIGH position, ground is then applied through the headlamp dimmer switch signal circuit to the BCM. The BCM then applies a ground to the headlamp high beam relay control circuit. This energizes the HI Beam relay, the relay then applies battery positive voltage through the LF and RF HI BEAM fuses to the LF and RF high beam headlamps. The ground for the left headlamps is supplied by G101 and the ground for the right headlamp is supplied by G100.
The BCM then sends a class 2 message to the instrument cluster in order to illuminate the high beam indicator lamp. If the headlamp switch is left in the HEAD position, the inadvertent power control feature will turn OFF the headlamps after 10 minutes after you turn the ignition switch to the OFF position. If you place the headlamp switch in the head position after the ignition switch has been turned OFF, or if the ignition switch is in ACCY position, the headlamps will remain ON until you turn them OFF or until the battery runs dead.
2007. How can I bleed the cooling system?
Hello. To 'bleed' your Buick's coolant system, open the 'bleeder valve' then start engine. Let engine 'warm' to operating temperature. Add coolant/water to reservoir tank if needed as system 'bleeds'. As coolant 'bleeds', 'forcefully' out of 'bleeder valve'; close and tighten it AND keep coolant/water level at FULL/HOT. Good luck and keep me informed; if you want to.
