What to do when My 2006 b9 Tribeca has 3 lights that keep coming on at the same time 3A 1 cruise 2 check engine 3 traction

they also provide live chat feature for instant help and it's very useful

I would be concerned that this issue is serious. Given all the parts that have been replaced already.

First get a leak down test performed to narrow down a possible cause. Both sides of the engine will require this test.

this will help determine a course of action
.
Here is a list of possible causes:
1. a plugged or restricted catalytic converter(s)
2. carbon buildup on the valves causing them to not fully close
3. issues with the active valve control system
4. less likely but possible the timing chain might have skipped

traction control and abs units both use the same wheel sensors
check for problem wires
run the fault codes to check for other areas and faults.

hello,do post your DTC'S,(diagnostic trouble codes) and may be i can help.many modern vehicles spring up a multitude of warning icon's on the dashboard,much to the alarm of it's owner,however,often it can be as simple as a dirty wheel speed sensor,which fails to provide the necessary information to the main (ABS/TRACTION control unit) and so then will inhibit the cruise control,as naturally it's unable to ascertain road wheel speed,and also throw up the engine management light,as the braking/traction control systems unable to supply correct information to the main engine computer(ECU,OR PCM) electronic control unit/power control module. hope this helps,but please supply any further information that you can,regarding your DTC'S, that are read out,try to get a full print off,if at all possible, cheers.

It could be your abs sensor that is messing up with your traction control system and the cruise control I hope that helps

or any of several reasons:

• You accidentally left the lights on or some other accessory that pulls power from the battery even when the ignition key is off.
• The battery is not being recharged while the vehicle is being driven (you have a charging problem)
• There is a key off parasitic electrical drain on the battery because a relay is sticking, a module is not shutting down, or there is a shorted diode in the alternator.

Take the car to Autozone or similar business for a free code read with a scanner. Depending on what turns up, they will be happy to sell you any needed parts.

The problem is a 7.5amp fuse in the fuse box under the hood labeled "EBR+1" or something like that. Replace that fuse and the problem should disappear.
