Component Testing
- Test for 70-110 Ω between terminals 85 and 86 of the KR75 powertrain relay.
- If not within the specified range, replace the KR75 powertrain relay.
- Test for infinite resistance between the following terminals of the KR75 powertrain relay:
- 30 and 86
- 30 and 87
- 30 and 85
- 85 and 87
- If not the specified value, replace the KR75 powertrain relay.
- Install a 20 A fused jumper wire between relay terminal 85 and 12 V. Install a jumper wire between relay terminal 86 and ground. Test for less than 2 Ω between terminals 30 and 87.
- If greater than the specified range, replace the KR75 powertrain relay.
