SHIM - EV-1 AUX CONT (Toyota TY00591-23553-81)

A worn shim can cause misalignment in auxiliary contact assemblies, leading to intermittent electrical continuity. The Toyota catalog reference for this aftermarket replacement part is TY00591-23553-81. This shim serves as a thin spacer to adjust the gap or position of an EV-1 auxiliary contact. Its plain mechanical function is to maintain precise clearance between contact surfaces. Without proper shim thickness, the contact may fail to close reliably, resulting in erratic circuit operation. This item ships at approximately 0.002 pounds. Verify the serial number or application, then call (562) 693-7748.
