- Ignition OFF, disconnect the Secondary Air Injection Pump Relay.
- Test for 50-75 Ω between terminals 85 and 86.
- If the resistance is not within the specified range, replace the Secondary Air Injection Pump Relay.
- Test for infinite resistance between the following terminals:
- 86 and 87
- 86 and 30
- 85 and 87
- 87 and 30
- If not the specified value, replace the Secondary Air Injection Pump Relay.
- Install a 15 A fused jumper wire between relay terminal 86 and B+. Install a jumper wire between relay terminal 85 and ground. Test for less than 2 Ω between terminals 87 and 30.
- If greater than the specified range, replace the Secondary Air Injection Pump Relay.
