DIAGNOSTIC TROUBLE CODE CHART
HINT:
Parameters listed in the chart may not be exactly the same as your reading due to \
the type of instrument
or other factors.
If a malfunction code is displayed during the DTC check in check mode, che\
ck the circuit for that code listed
in the table below. For details of each code, turn to the page referred to under the ’’See page ’’ for the respe-
cire ’’DTC No.’’ in the DTC chart.
