Starter Relay
- Remove starter relay from Intelligent Power Module (IPM). IPM is located on left side of engine compartment, next to battery. See Figure.
- Measure resistance between terminals No. 85 and 86 on starter relay. See Fig 1. If resistance is not 70-80 ohms, replace starter relay. If resistance is 70-80 ohms, go to next step.
- Check for continuity between terminals No. 30 and 87 on starter relay. If continuity exists, replace starter relay. If no continuity exists, connect a jumper wire between negative battery terminal and terminal No. 85 on starter relay. Connect another jumper wire between positive battery terminal and terminal No. 86 on starter relay.
- Starter relay should now be energized. Check for continuity between terminals No. 30 and 87 on starter relay. If continuity exists, starter relay is okay. If continuity does not exist, replace starter relay.
