DIAGNOSTICS - ASSEMBLY INSTRUMENT 04-943

(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.
Standard voltage

32 31 30 29 28 27 26 25 24 23 22 21 20 19 18 17
Multimeter connection Standard value 04
C013 (1) -ground
1 3 Battery voltage
C013 (3) -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
