04-480 DIAGNOSTICS - ASSEMBLY INSTRUMENT

(c) Use a multimeter to measure the voltage
between pins 1 and 3 of connector C013 of
the combination instrument C013 and the
C013
ground.

Check whether the result is normal?
Yes> go to step 3
No > If battery voltage is unavailable in pin 3 of connector C013 of combination
instrument, repair the open circuit of the circuit between F7 (7.5A) and pin 3 of
connector C013 of the combination instrument. If battery voltage is unavailable in pin
1 of connector C013 of combination instrument, repair the open circuit of the circuit

between F26（10 A） and pin 1 of connector C013 of the combination instrument.

3 . Check the ground circuit of combination instrument
(a) Ignition Switch: OFF.

(b) Use a multimeter to measure the resistance
between pins 3 of connector C013 of the
combination instrument and the ground.

Check whether the result is normal?
Yes> replace combination instrument assembly.

No > Repair the circuit between pin 2 of connector C013 of combination instrument
and the ground.

4 . Check the power-supply short circuit of combination instrument
(a) Ignition Switch: OFF.
