Low Fuel Indicator Light Test
NOTE: For the low fuel indicator circuit diagram, refer to
the gauge assembly circuit diagram (see page 23'2311.
1. Check the No. 25 (7 5 A) luse in the driver's under
dash fuse/relay box before testing
2. Park the vehicle on level ground.
3.
4.
Drain the luel into an approved container. Reinstall
the fueltank drain bolt with a new washer.
Add less than 4L (1 1 U.S Gal, 0.9 lmp Gal) of fuel,
and turn the ignition switch ON (ll). The low fuel
indicator light should come on within four minutes'
. lf the light comes on within four minutes, go to
step 8.
. lf the light does not come on within four min-
utes, go to step 5.
Remove the access panel lrom the Iloor'
Turn the ignition switch OFF, then disconnect the
fuel tank sending unit 3P connector.
Connect the fuel tank sending unit 3P terminals No'
1 and No. 3 with a jumPer wire
. lf the light comes on, replace the fuel gauge
sending unit (see Page 23 1421
. lf the light does not come on, check for:
- An open in the GRN/YEL wire between the
fuel gauge sending unit and the fuel gauge
- A blown bulb.- A poor ground (G552)
