Diagnosis Procedure
a. Using a digital multimeter, measure the voltage between positive battery terminal and negative battery
terminal.
b. The battery voltage should be between 11 and 14 V.
a. Turn ignition switch to LOCK.
b. Disconnect the negative battery cable.
c. Disconnect the instrument panel wire harness connector
I-015.
d. Connect the negative battery cable.
e. Turn ignition switch to ON.
f. Using a digital multimeter, measure the supply voltage
between instrument panel wire harness connector I-015
and body ground according to the value(s) in the table
below to check if system power source control circuit is
normal.
Standard Voltage
g. Turn ignition switch to LOCK.
h. Disconnect the negative battery cable.
i. Disconnect the instrument panel wire harness connectors
I-015 and I-007.
j. Using a digital multimeter, check for continuity between
instrument panel wire harness connectors I-015 and
I-007 according to the table below.
