If the tachometer needle shows initial function, but
tachometer does not move with the engine starts,
check as follows:
Remove the screen garnish (page 3-18).
Connect the peak voltage adaptor to the combina-
tion meter 28P (Gray) connector terminal and
ground with the connector connected.
Start the engine and measure the tachometer input
peak voltage.
If the value is normal, replace the combination
meter printed circuit board.
If the measured value is below 10.5 V, replace the
PCM.
If the value is 0 V, inspect the following:
– Inspect the tachometer signal line open circuit
with test probe (page 22-23)
– Inspect the tachometer signal line open circuit
with test harness (page 22-23)
TACHOMETER SIGNAL LINE OPEN CIRCUIT
INSPECTION WITH TEST PROBE
Disconnect the following:
– Combination meter 28P (Gray) connector (page
22-10)
– ECM 33P (Black) connector (page 6-98)
Check the continuity between the combination
meter and ECM 33P connectors of the wire side.
There should be continuity.
If there is no continuity, check for open circuit in
Blue/yellow wire.
TACHOMETER SIGNAL LINE OPEN CIRCUIT
INSPECTION WITH TEST HARNESS
Connect the test harness between the wire harness
and ECM 33P connector (page 6-17).
Disconnect the combination meter 28P (Gray) con-
nector (page 22-10).
Check the continuity between the test harness and
combination meter connector of the wire side.
There should be continuity.
If there is no continuity, check for open circuit in
Blue/yellow wire.
