Voltage should be battery voltage. If voltage is as specified, check for poor, loose, damaged and corroded terminals at ECM. Repair if necessary and go to step  3 . If voltage is not as specified, go to next step.
  2. Turn ignition off. Check P/TRAIN fuse (15 amp) in engine compartment fuse/relay box. If P/TRAIN fuse condition is okay, check circuit between ECM connector terminal B18 (White/Red wire) and battery voltage supply (Black wire). See WIRING DIAGRAMS article. if circuit is faulty, repair as necessary and go to step  4 . If circuit is okay, go to next step. If P/TRAIN fuse is blown, repair short circuit between battery voltage supply(Black wire) and ECM connector terminal B18 (White/Red wire). Repair as necessary, replace P/TRAIN fuse (15 amp) and go to step  4 .
  3. Temporarily install a known-good ECM and check for proper operation. If problem is corrected, replace ECM and go to next step.
