Component Testing
- Ignition OFF, disconnect the KR25 secondary air injection pump relay.
- Test for 70-110 Ω between terminals 85 and 86.
- If the resistance is not within the specified range, replace the KR25 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 KR25 secondary air injection pump relay.
- Install a 20 A fused jumper wire between relay terminal 86 and 12 V. 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 KR25 secondary air injection pump relay.
