caughlins :

The turn signal switch is broken. This can cause several issues mainly be cause it causes the battery to go flat. What type of readings is the emission tester not getting? Usually they hook up a scan tool and check for monitors to be set. Then they also take an exhaust sample and some check to see if the vapor system is sealed. If it is the readiness this could be related to the low battery as just key on the scanner might not communicate properly. Let me know which reading they are not getting. -Colin-

he said he is not getting communication

with the computer

JACUSTOMER-2vzegwjd- :

thay say not comunicating with thier computer

JACUSTOMER-2vzegwjd- :

yhay say thier computer cant comunicate with the car

caughlins :

So the battery needs to be charged and the turn signal switch fixed. Or he can try it with the car running. -Colin-

JACUSTOMER-2vzegwjd- :

thay say there not getting any comunication

caughlins :

Is this with the battery fully charged or the car running? Also have they tested this style vehicle before? The Bentley's communicate on a data bus that not all scan tools work with. What type of tool are they using? -Colin-
