3. Check the tachometer
Start the engine at DC 13.5V±0.5V, ambient temperature 25 ±5 , ℃℃externally connect with
trouble diagnostic instrument to measure the rotation speed, the value measured should
correspond to the instrument display within a permissible range, as shown in the table below.
Tachometer permissible range (see Table 4-5)
Table 4-5
Value measured (rpm) Instrument display (rpm)
1000
900～1100
3000
2800～3200
5000
4800～5200
4. Check the fuel gauge
(1) Disconnect the harness connector of fuel level sensor, ignition switch ON-position, check the
pointer of fuel gauge, normally at position E;
(2) Connect the connector terminals 2-F11 and 3-F11 at the side of fuel level sensor wire, ignition
switch ON-position, check the pointer of fuel gauge, normally at position F;
5. Check the fuel level warning lamp, disconnect the harness connector of fuel level sensor,
ignition switch ON-position, normally the pointer of fuel gauge should be at position E, fuel level
warning lamp lit.
6. Check the water thermometer
(1) Disconnect the harness connector of coolant temperature sensor, ignition switch ON-position,
check the pointer of water thermometer, normally at position C;
(2) Connect the connector terminal at the side of coolant temperature sensor wire to the body, and
check the pointer of water thermometer, normally at position H;
7. Check the seat belt reminder warning lamp
(1) Ignition switch ON-position, driver’s seat belt buckle open, check the seat belt reminder
warning lamp, normally lit;
(2) Ignition switch ON-position, driver’s seat belt buckle in, check the seat belt reminder warning
lamp, normally unlit;
(3) Disconnect the buckle switch connector, and connect the connector terminal at the side of
buckle switch wire to the body. Ignition switch ON-position, driver’s seat belt buckle in, check the
seat belt reminder warning lamp, normally lit;
8. Check the oil pressure warning lamp
Disconnect the harness connector of oil pressure warning lamp, ignition switch ON-position,
connect the connector terminal at the side of oil pressure warning lamp switch wire and the body,
normally, the warning lamp should be lit.
9. Check the oil pressure warning lamp switch
Disconnect the harness connector of oil pressure warning lamp, and check the conductivity
between the terminal of oil pressure warning lamp switch and the body. When the engine shuts
down, the wiring between terminal and body should be conducted; when the engine runs, the
wiring between terminal and body should be not conducted.
