CAUTION

To prevent damage to diagnostic tool MB991958, always 
turn the ignition switch to the "LOCK" (OFF) position 
before connecting or disconnecting diagnostic tool 
MB991958.
1. Connect diagnostic tool MB991958 to the data link 

connector.

2. A/T select lever: "P" position or Manual gearshift in 

"NEUTRAL"with handbrake "ON".

3. Turn the ignition switch to "ON" position.

4. Start the engine.

5. Run the engine.

6. Select MPI system data list and take a reading of the engine 

speed.

Item 22: CKP SENSOR

7. Compare the engine speed shown in the diagnostic tool with 

that shown on the tachometer. The engine speeds shown on 
the tachometer should correspond to the table below.

NOTE: The following standard value assumes that battery 
voltage is 13.5 volts.

FUEL LEVEL SENSOR CHECK

M1543001300037

1. Remove the rear seat cusion assembly. (Refer to GROUP 

52A, Rear Seat Assembly 

P.52A-55

.)

2. Remove hole cover and remove the fuel pump module and 

fuel level sensor (sub).

Tightening torque: 1.5 

± 0.5 N⋅m (14 ± 0.5 in-Ib)

FUEL LEVEL SENSOR RESISTANCE

1. Check the resistances between  fuel level sensor main 

terminals 1 and 2 as well as sub terminals 1 and 2 of the fuel 
pump module, respectively.

Standard value:

2. Check that resistance value changes smoothly when the 

float moves slowly between points. 

3. If all checks are correct, go to fuel unit height check. If any 

check is not correct, replace the fuel pump module or fuel 
level sensor (sub).

 GENERAL DESCRIPTION

BABBAIDI

The unit will display vehicle date in the "ON" position. 
The unit will scroll through the system showing cur-
rent data and will revert to the previously selected 
mode.
Some of the combination meter indications are 
based on information from ECUs via CAN bus com-
munication. If there is any failure in the meters con-
nected via the CAN bus communication, diagnose 
the CAN bus communication system. The following 
instruments, indicator lights and warning lights in the 
combination meter are controlled by ECUs via CAN 
bus communication.

The meter combination does not include a buzzer, 
but it sends a request to sound buzzer on ETACS via 
the CAN system.
