A/C Clutch Relay (Except 3.5RL)
NOTE:
On MDX & RSX models, this type of relay test is also useful when checking Ignition Coil relay, Air Fuel Sensor relay, PGM-FI main relays 1 and/or 2, and Throttle Actuator Control Module relay (MDX only).
Relay is located in underhood fuse/relay box. Remove relay. Check continuity between terminals No. 1 and 2. See Figure . If continuity is present, replace relay. Using fused jumper wires, connect 12-volt battery power and ground to terminals No. 3 and 4. If continuity is not present between terminals No. 1 and 2, replace relay.
