PGM-FI Main Relay
Description
The PGM-Fl main relav actuallv contains two individual
relays. This relay is located at the passenger side of the
cowl. One relay is energized whenever the ignition is on
which supplies the battery voltage to the ECM/PCM,
power to the fuel injectors, and power for the second
relay. The second relay is energized for two seconds
when the ignition is switched on, and when the engine
is running, to supply power to the fuel pump

Belay Testing
NOTE: lf the engine starts and continues to run, the
PGM-FI main relay is OK.
1. Remove the glovebox and the passenger's dash-
board lower cover (see section 20).
2. Remove the PGM-FI main relay
3. Aftach the battery positive terminal to the No. 2 ter-
minal and the battery negative terminal to the No. 1
terminal of the PGM-Fl main relay. Then check for
continuity between the No. 5 terminal and No. 4 ter-
minal of the PGM-FI main relay
. lfthere is continuity, go on to step 3.
. lf there is nocontinuity, replacethe PGM-Fl main
relav and retest.

NOTE: Keep all foreign particles out of the transmis-
ston,
1. Warm up the engine to normal operating tempera-ture (the radiator fan comes on)
Park the vehicle on level ground. Turn off theengine.
Remove the dipstick (yellow loop) from the trans-mission, and wipe it with a clean cloth.
Insert the dipstick into the transmission.
DIPSTICK
Remove the dipstick and check the fluid level. lt
should be between the upper and lower marKs.
lf the level is below the lower mark. pour the recom-mended fluid into the filler hole to bring it to the uppermark, Always use Genuine Honda Premium FormulaAutomatic Transmission Fluid (ATF). Using a non-Honda ATF can affect shift oualitv.
