 As technology advances, so does its brake problems…….

If you have a customer complaining of unexpected vehicle deceleration, and/or steering pull with no brake light illumination, Stop! And read this before you believe it is a bad brake caliper and/or brake hose.

Honda is still in debate on how to go about the recall, after some 200 plus complaints to the NHTSA (National Highway Traffic Safety Administration). After four months, they have found out that oxidation in the wiring or a loose bolt can cause the sudden braking and/or pulling to one side, while driving. (See Figure 1 of the 47 Pin electrical connector)

The recall of 183,000 vehicles in the U.S. alone includes 101,000 Honda Pilot, 60,000 Acura MDX and 21,000 Acura RL sedans, all from the 2005 model year. It also includes 800 of the Acura 2006 MDX models. Honda now says the defect is in the vehicles’ stability control system, which helps the driver keep control by applying the brake selectively.
NHTSA focused their investigation on the “Brake Assist” function of the VSA (Vehicle Stability Assist) system. The Honda VSA control unit learns the current driver’s regular braking characteristics by monitoring the brake pressure sensor and the brake pedal position at each stop. Using these inputs and their values, the VSA control unit can learn the driver’s standard braking habits, and then can determine the difference between a normal stop and a panic stop.
If the VSA light is on and there is a code 84 logic code failure. Take note to all codes, clear codes and road test. Re-check for codes and if the 84 comes back in, then replace VSA. However, if the TPMS light is on, this will disable the VSA system, and both the TPMS and the VSA light will be on. Take care of the TPMS light first, and then if VSA light is still on, follow the step above. After replacing the VSA you will need to do a sensor memorization procedure. Follow the steps in figure 2 and 3. You will need a connector SCS SERVICE CONNECTOR O7PAZ-0010100. Do not use a jumper wire!!

 

For now, cleaning the connector with electrical cleaner spray and using Dielectric grease should help, until Honda decides on a new electrical connector, or harness. As a rule of thumb, use best practices when it comes to electrical connectors – use dielectric grease whenever possible, unless instructed not to do so.
