Acura Repair Questions? Ask a Mechanic for Answers ASAP
Those codes are usually associated with a bad Vehicle Stability Assist (VSA) module.
Acura/Honda doesn't allow for comprehensive diagnostics other than those performed with their proprietary tools. In this case, code 81 from a Honda Diagnostic System scan tool (HDS) will confirm a bad VSA module. Without an HDS, diagnosis is confined to checking that the connector and wiring are OK, then trying a known-good VSA module.
