Is there battery voltage?
YES—Check for loose or poor connections at PCM
connector terminal A4. If the connection is OK,
update the PCM if it does not have the latest
software, or substitute a k n o w n - g o o d PCM
(see page 14-7), then recheck. If the s y m p t o m /
indication goes away w i t h a k n o w n - g o o d PCM,
replace the original PCM. •
NO—Check for a b l o w n No. 8 fuse in the under-
hood fuse/relay box, and check the PGM-FI main
relay. If the fuse and the relay are OK, repair an
open in the w i r e between PCM connector terminal
A4 and the under-hood fuse/relay box, then go to
step 16.
16. Clear the DTC w i t h the HDS.
17. Test-drive the vehicle for several minutes in the D
position in all five gears.
18. Monitor the OBD status for P0979 in the DTCs/
Freeze Data in A/T M o d e M e n u for a pass/fail.
Does the result indicate a pass?
YES—The problem has been corrected. •
NO—Return to step 7 and recheck.
