-Performance Test
NOTE: Before staning the following checks. disconnect
the wire from terminal M. and make a connection as
described below using as heavy a wire as possible (prefer-
ably equivalent to the wire used for the car).
Pull-in CoilTest:
Connect the battery as shown, lf the staner pinion pops
out. it is working proPerly.
CAUTION: Do not leavo tho batterv connost€d for more
than 10 seconds.
Hold-in Coil Test:
Disconnect the battery from the M terminal' lf the pinion
does not retract, the hold-in coil is working properly.
CAUTION: Do not loavc lhe battsry connected for mot6
than 10 ssconds.
Retracting Tosi:
Disconnect the battery also from the body. lf the pinion
retracts immediately, it is working properly.
GAUTION: Do not loave the baftery conn€ctod tor more
than 10 seconds.
Startor No-load Tost:
Clamp the starter firmly in a vise.
Connect the starter to the battery as described in
the diagram below, and confirm that the motor
starts and keeps rotating.
1.
3, lf the electric current and motor speed
specifications when the battery voltage is
the starter is working ProPerly.
Specifications:
80 A or less (Electric current),2,600 rpm or more
(Motor-speed)

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)
