INSPECT FUEL RECEIVER GAUGE
(a) Disconnect the L5 fuel sender gauge connector.
(b) Check the fuel receiver gauge operation when the 

ignition switch is turned to the ON position.
OK:

Needle position is on EMPTY.

(c) Connect terminals 2 and 3 on the wire harness side 

connector of the fuel sender gauge.

(d) Check the fuel receiver gauge operation when the 

ignition switch is turned from OFF to ON.
OK:

Needle position is on FULL.

(e) Reconnect the fuel sender gauge connector.

5.

INSPECT FUEL LEVEL WARNING LIGHT
(a) Disconnect the fuel sender gauge connector.
(b) Turn the ignition switch to the ON position, then 

check that the fuel level needle indicates EMPTY 
and the fuel level warning light comes on.
OK:

Fuel level warning light comes on.

(c) Reconnect the fuel sender gauge connector.

6.

INSPECT ENGINE OIL PRESSURE WARNING LIGHT
(a) Disconnect the engine oil pressure switch 

connector.

(b) Turn the ignition switch to the ON position.
(c) Ground the terminal of the wire harness side 

connector, then check the engine oil pressure 
warning light.
OK:

Engine oil pressure warning light illuminates.

(d) Reconnect the engine oil pressure switch connector.

7.

INSPECT BRAKE WARNING LIGHT
(a) Inspect the parking brake warning light.

(1) Disconnect the parking brake switch connector.
(2) Turn the ignition switch to the ON position.
(3) Ground the terminal of the wire harness side 

connector, then check the parking brake 
warning light.
OK:

Brake warning light illuminates.

(4) Reconnect the parking brake switch connector.

(b) Inspect the brake fluid level warning light.

(1) Disconnect the brake fluid level warning switch 

connector.

(2) Turn the ignition switch to the ON position.
(3) Connect a terminal to the other terminal of the 

wire harness side connector, then check the 
brake fluid level warning switch.
OK:

INSPECT BRAKE FLUID LEVEL WARNING SWITCH
(a) Remove the reservoir tank cap and strainer.
(b) Disconnect the brake fluid level warning switch 

connector.

(c) Measure the resistance between the terminals.

Standard resistance:

Float inside reservoir tank is in high position 
(switch OFF): 10 k 

Ω or higher

(d) Use a syphon or a similar tool to drain fluid out of 

the reservoir tank.

(e) Measure the resistance between the terminals.

Standard resistance:

Float inside reservoir tank is in low position 
(switch ON): Below 1 

Ω

(f)

Pour the fluid back into the reservoir tank.

(g) Reconnect the brake fluid level warning switch 

connector.

(h) Reinstall the reservoir tank cap and strainer.

OIL MAINTENANCE INDICATOR RESETTING 
PROCEDURE (U.S.A. only)

(a) Set the window display located inside the 

combination meter to the Trip A indication.

(b) Turn the ignition switch OFF.
(c) While pressing the ODO/TRIP display change 

switch (reset switch) (for at least 5 seconds), turn 
the ignition switch ON.

(d) When the reset procedure has been completed 

successfully, the MAINT REQD indicator light turns 
off and the ODO/TRIP meter indicates 0 (zero) and 
then returns to its regular display.
HINT:
If the reset fails, the MAINT REQD indicator light 
remains illuminated. Perform the procedure again.
