FE13 - Check BLR Circuit Continuity
- Key "OFF".
- Disconnect blower motor relay.
- Breakout box installed, PCM disconnected.
- Measure resistance between test pin 14 (test pin 29 for CD4E and Calif. M/T) at breakout box and BLR circuit at Power Distribution box (refer to Pinpoint Test schematic). FE - Testing Schematic
- Is resistance less than 5.0 ohms?
Yes -- Go to FE14. FE14 - Check BLR Circuit For Short to Ground
No -- Service open circuit. Remove breakout box. Reconnect all components. Verify elimination of idle speed concern.
