Hi, Thank you for asking your question on JustAnswer, my name is XXXXX XXXXX I will be assisting you today with your question.
NOTE: The generic electronic module (GEM)/central timer module (CTM) must be reconfigured upon replacement. Refer to the New Generation STAR (NGS) Tester help screen on the Ford Service Function (FSF) card to program the Tire Size, Axle Ratio.
NOTE: When configuring the GEM, the NGS Ford Service Function (FSF) Card version 1.1 will display the following negative response:
Use (DVOM) (Digital Volt Ohm Meter) to check for the continuity between terminal 2 and all other terminals. If the resistance is 5 ohms or less between terminal 2 and any other terminal, replace the relay. If resistance is greater than 5 ohms, continue with the test. Use two jumper wires to connect relay terminals 1 and 3 directly to the positive battery terminal. Use 73 Digital Multimeter set in the volts position to check for voltage at terminal 4. If battery voltage is not indicated, replace the relay. If battery voltage is indicated, connect a third jumper wire to terminal 2 and ground the jumper wire to a known good ground. Check for voltage at terminal 5. If battery voltage is not indicated, replace the relay.
Thank you for asking your question on JustAnswer.
