Air Pump Relay Test (S2000)

Air pump relay is located at left front of engine compartment, right of air pump. See COMPONENT LOCATIONS . Remove air pump relay. Using a fused jumper wire, connect battery voltage to air pump relay terminal B1. Using another jumper wire, connect battery ground to relay terminal B2. See Fig 1. Check for continuity between relay terminals A1 and A2. If continuity exists, relay is okay. If continuity does not exist, replace air pump relay and retest.
