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)

LRemove the driver's dashboard lower cover and
knee bolster (see section 20).
Disconnect the connectors from the daytime run-
ning lights control unit.
Inspect the connector and socket terminals to be
sure they are all making good contact.
lf the terminals are bent, loose or corroded. repair
them as necessary, and recheck the system.
lf the terminals look OK, make the following
input tests at the connector,- lf any test indicates a problem, find and correct
the cause, then recheck the system.- lf all the input tests prove OK, the control unit
must be faulty; replace it.
