If your TMPS is not functioning or disconnected, does this lock he VSA into the ON position?

 

Yes

thought so... thanks

 

Ross... have any of you tech's discussed a way to bypass the TMPS sensors?

 

Not really. I've never had my hands one one of them long enough to figure it out. my first guess would be to start pulling fuses.

 

Well.. this did work, however that fuse has several interior systems associated with it as it is a multi function fuse. Thankfully the fuse has multiple connections and it maybe possible to modify the fuse itself so that only the VSA fuse is disconnected

 

De-pin the wires that power up the TPMS unit?

 

Well I unseated the VSA fuse... it's a multi system fuse. I think I can buy a second fuse and modify that fuse to run all systems minus the VSA module

 

Hey ross... is the accord VSA brake based or ECU based?

he reason I ask is because the car feels much stronger with the VSA fuse pulled. seat of the pants stuff though

 

Never mind... I found it:


Standard Vehicle Stability Assist™ (VSA ®) with Traction Control and Brake Assist
Vehicle Stability Assist (VSA) is an Electronic Stability Control system that works in conjunction with the Accord's drive-by-wire throttle and its 4-channel ABS systems to enhance controllability while the vehicle is accelerating, braking, cornering or when the driver makes a sudden maneuver. VSA functions by applying brake force to one or more wheels independently while also managing the throttle, ignition and fuel systems to help the vehicle maintain the driver's intended path of travel.

The VSA system constantly analyzes data from seven sensors that monitor wheel and vehicle speed, steering input, lateral G forces and yaw rate. It compares the driver's control inputs with the vehicle's actual response. Whenever the actual response falls outside of a predetermined acceptable range, VSA intervenes with a corrective action.

For instance, if VSA detects an oversteer condition, the system may apply braking force to the outside front and rear wheels to counteract the unintended yawing effect. In the event of understeer, VSA may apply braking to the inside rear wheel while reducing engine power to help return the car to its intended course. VSA also provides a limited-slip differential effect for the front wheels by applying braking force to a slipping wheel, thereby redirecting driving force to the wheel with more traction.
