FE23 - Check DRL Circuit Continuity
- Key "OFF".
- Breakout box installed, Powertrain Control Module (PCM) disconnected.
- Disconnect Daytime Running Lamps relay.
- Measure resistance between test pin 14 at breakout box and Daytime Running Lamps relay signal pin cavity at DRL relay female connector (refer to Pinpoint Test schematic).
- Is resistance less than 5.0 ohms?
Yes -- Go to FE24. FE24 - Check DRL Circuit For Short to Ground
No -- Service open circuit. Remove breakout box. Reconnect all components. Verify elimination of idle speed concern.
