Diagnosis- combination meter

(c) Use a multimeter to measure resistance
to ground of connector pin 1 of
speedometer sensor C048.
Resistance: >1MΩ

Is check result normal?
Yes > Replace combination meter. 04
No > Repair line to ground short between connector pin 14 of combination meter B034 and
connector pin 1 of speedometer sensor C048.
4. Checking speedometer sensor
(a) Remove speedometer sensor.
(b) Turn spindle of speedometer sensor.
(c) Use a multimeter to measure resistance
between connector pins 2 and 3 of
speedometer sensor C048.
Pulse signals: 8 pulse resistance signals
per turn

Is check result normal?
Yes > Go to step 5.
No > Replace speedometer sensor.
5. Checking signal circuit of speedometer sensor

(a) Use a multimeter to measure resistance
to ground of connector pin 3 of
speedometer sensor C048.
Resistance: >1MΩ
