Check-list List of checking procedures EDC MS 5 1. Checks while engine is stationary (Ignition off, control unit not connected) Engine temperature [ 25 ° C Control unit not (!!!) connected, cable harness adapter connected Measure resistance between PIN+ and PIN– with multimeter 1) Exact measurements are possible only at defined temperatures. 2) Resistance approximately 230–460 W with engine at operating temperature (approximately 80 ° C) 3) only D2866LUHxx and D2876 23 PIN+ PIN– Setpoint Measured value Control rod position sensor1) 11 9 18–25 Ohms . . . . . . . . . . . . . . . .
