New relays are not much more than that. Also, there are at least seven of those 8666 relays that are identical & interchangeable. Good way to test one is to swap it with another.Nestle555,
Found some info on the web that older Malibus had a problem with a relay not making a good conection. Since I was having this problem too I figured what could it hurt to try this fix. I removed the relay(#49 I think) located next to the battery under the hood and reinserted it several times and also applied a little dielectric grease. So far so good, the problem hasn't recurred in the last three days. Try it, you won't do any damage and if it doesn't work you'll only be out $2.99 for a tube of grease.
Cleaning the contacts may be, but I don't really think electronics like much in the way of lubricant in them ...I'm having the same issue with the brake light intermittently coming on. I had the pedal position sensor replaced but this is still an issue. Is cleaning & lubing the BCM the answer?
The real answer is to get the shop that replaced the part to actually FIX THE PROBLEM........whatever that takes.I had the pedal position sensor replaced but this is still an issue. Is cleaning & lubing the BCM the answer?
Are all three stop lamps "intermittently coming on" (because the high-mount includes an additional circuit)?I'm having the same issue with the brake light intermittently coming on. I had the pedal position sensor replaced but this is still an issue. Is cleaning & lubing the BCM the answer?
After replacing the Brake Pedal Position sensor, the BCM must be recalibrated for the new sensor. If the issue is not solved, the problem may well be in the BCM or the harness. I think you'll need a dealer to sort it out.Yes. All three lamps are on when this problem occurs.
My car is fixed. I will quote the invoice.
"Customer states Traction Control light on and ESC light on and rear brake light on all the time. CK codes c0131 ABS/TCS system pressure circuit malfunction. Perform bulletin 08-05-22-009c to correct."
The TSB says --Disconnect the C2 or X2 connector, Add dielectric lubricant and reconnect the connector.

Dealer serviceman said mine was the second car this week to have this problem.
I would have to wonder if they did as it requires a tech 2. Have you talked to them about it?I had it serviced at a local car shop so I'm not sure if they recalibrated the sensor.
Dealers almost always behave that way. Even with something as seriously life & death as the stop lamps. They are waiting for a dtc to tell them what to do. Intermittent electrically issues can take time to track down. If you have a way of capturing video do so & show that to them. I think you need to pursue the possibility that the BCM was not zeroed out for the replacement BPPS & the home position is just too close to the pedal top position.I did bring it into a dealership to deal with a recall and told them about the issue but they weren't able to duplicate the problem so they didn't try to guess as to what the problem might have been and replace unnecessary parts.
