Ground Circuits

MCU is grounded through pins No. 2, 14, 19 and 24. Pins No. 2, 14 and 24 are Brown wires. Pin No. 19 is Brown/Orange wire. Ground point is on right front shock tower. Check that battery voltage exists between pins No. 2, 14, 19 and 24. If voltage does not exist, check for open wire circuit. See WIRING DIAGRAMS article for more information.
