Replace instrument cluster,

(a) Replace the combination instrument and refer to 11.6.7.1 Replacement of Combination

Instrument Assembly.

Confirm the completion of repair.

Diagnostic steps:

1 General

inspection

(a) Inspect whether combined instrument wire harness connector has damage, bad connection,

ageing and loose conditions.

Inspect if the result is normal

2

Inspect the communication between the terminal No.1 of the fuel level sensor wire
harness connector SO27 and the terminal No.4 of the combination instrument wire
harness connector IP01.

(a) Measure resistance between fuel level sensor wire harness connector SO27 terminal No.1 and

combined instrument wire harness wire IP01 terminal No.4.

Standard resistance: less than 1 Ω

Is the resistance at a specified value?

No

Fault discovered by maintenance

Yes

Inspect and inspect the circuit between the terminal No.1 of the fuel level sensor wire
harness connector SO27 and the terminal No.4 of the combination instrument wire
harness connector IP01.

(a) Make sure that fuel level sensor wire harness connector SO27 terminal No.1 and combined

instrument wire harness connector IP01 terminal No.4 are connected.

Check Fuel gauge work is not normal,
