.

Q: Is the harness wires from combination meter connector

C-30 to ignition failure sensor connector B-01 <2.4L
engine>, distributor assembly connector B-27 <3.0L
engine>, automatic compressor controller connector C-
16 <3.0L engine> in good condition?
YES : There is no action to be taken.
NO : Repair it. The tachometer should work normally.

CIRCUIT OPERATION

•

The ignition switch (IG1) circuit is the power
source for the fuel gauge.

•

The resistance value fluctuates causing the
circuit current to fluctuate when the fuel gauge
unit the float moves up and down.

•

The fuel gauge moves the needle by the circuit
current.

TECHNICAL DESCRIPTION (COMMENT)
If the ignition switch (IG1) circuit is open, the gauge
needle will not move at all. If the ground circuit is
open, the gauge needle will move up to its extreme
position.

TROUBLESHOOTING

•

Malfunction of the fuel pump module (fuel gauge
unit)

•

Malfunction of the combination meter (printed-
circuit board or fuel gauge assembly)

DIAGNOSIS

Required Special Tool:
MB991223: Harness Set

STEP 1. Check the speedometer operation.

Q: Does the speedometer work normally?

YES : Go to Step 2.
NO : Refer to Inspection Procedure 1
