Some PGM-FI problems will also make the D4 indicator light come on. After repairing the PGM-FI system, disconnect the Back Up fuse (7.5 A) in
the under-hood fuse/relay box for more than 10 seconds to reset the A/T control unit memory.
NOTE: Disconnecting the Back up fuse also cancels the radio preset stations and the clock setting. Make note of the radio presets before removing
the fuse so you can reset them.
NOTE: Only the A and D sections of the Test Harness are used for A/T troubleshooting. Unless otherwise noted, use only the Digital Multimeter, KS
-AHM32-003, for testing.
