First diagnostic step
Measure sensor circuit resistance at sensor/lock switch connector J4 on ERC (should read approx. 1100 ohms at room temperature). If circuit appears normal, re-install sensor disconnect plug to ERC and measure sensor resistance and solder joints on back of ERC circuit board. If circuit is open, problem is in the connector block - remove terminals and reform to restore contact pressure.
