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,
