1. Power Relay - Test Use this chart to identify the types of the relay, then do the test listed for it. NOTE: Do not use pliers to remove a relay. Pliers will damage the relay. Relay Test A/C compressor clutch relay A/C condenser fan relay Blower motor relay Console accessory power socket relay Driver's seat heater relay (high) (with seat heater) Electronic throttle control system (ETCS) control relay Front accessory power socket relay Fog light relay (with fog light) Front passenger's seat heater relay (high) (with seat heater) Horn relay Ignition coil relay Interior light cut relay PGM-FI main relay 1 PGM-FI main relay 2 PGM-FI subrelay Power window relay Radiator fan relay Real time AWD relay Rear window defogger relay Starter cut relay Normally-open four-terminal type Driver's seat heater relay (low) (with seat heater) Fan control relay Front passenger's seat heater relay (low) (with seat heater) Five-terminal type Normally-Open Four-Terminal Type Check for continuity between the terminals: There should be continuity between terminals No. 1 and No. 2 when battery power is connected to terminal No. 3, and battery ground is connected to terminal No. 4. There should be no continuity between terminals No. 1 and No. 2 when battery power is disconnected. Five-Terminal Type Check for continuity between the terminals: There should be continuity between terminals No. 1 and No. 2 when battery power is connected to terminal No. 3, and battery ground is connected to terminal No. 5. There should be continuity between terminals No. 1 and No. 4 when battery power is disconnected.

1. Relay Control Module - Test The relay control module is part of the under-hood fuse/relay box, and contains these relays: Left headlight low beam relay Right headlight low beam relay Taillight relay Windshield wiper motor relay Windshield wiper intermittent relay Windshield wiper high/low relay Test each relay circuit as shown. If any of these relay circuit fails the test, replace the relay control module. Left Headlight Low Beam Relay There should be battery voltage at terminal B9 when battery power is connected to terminals B8, and body ground is connected to terminal B6. There should be no voltage at terminal B9 when power is disconnected. Right Headlight Low Beam Relay There should be battery voltage at terminal B2 when battery power is connected to terminals B7, and body ground is connected to terminal B6. There should be no voltage at terminal B2 when power is disconnected. Taillight Relay There should be battery voltage at terminal A2 when battery power is connected to terminal A8, and body ground is connected to terminal A1. There should be no voltage at terminal A2 when terminal A1 is disconnected. Windshield Wiper Motor Relay There should be continuity between terminals A16 and A3, and terminals A16 and A6 when battery power is connected to terminal A9, and body ground is connected to terminal B1. There should be no continuity between terminals A16 and A3, and terminals A16 and A6 when power is disconnected. Windshield Wiper Intermittent Relay There should be battery voltage at terminal A12 when battery power is connected to terminals A16 and A9, and body ground is connected to terminals B1 and A6. There should be no voltage at terminal A12 when terminal A6 is disconnected. Windshield Wiper High/Low Relay There should be battery voltage at terminal A13 when battery power is connected to terminals A16 and A9, and body ground is connected to terminals B1, A3, and A6. There should be no voltage at terminal A13 when terminal A3 is disconnected.
