CRUISE MAIN INDICATOR LIGHT CIRCUIT
CIRCUIT DESCRIPTION
The ECM detects a cruise control switch signal and sends it to the combination m\
eter via BEAN. Then
the CRUISE main indicator light comes on.
The CRUISE main indicator light circuit uses BEAN for communication. If there are any ma\
lfunctions
in this circuit, check for DTCs in the multiplex communication system.
INSPECTION PROCEDURE
1 READ VALUE ON INTELLIGENT TESTER II
(a) Connect the intelligent tester II to the DLC3.
(b) Turn the ignition switch to the ON position and turn the intelligent test\
er II main switch on.
(c) Select the item below in the ”DATA LIST”, and read the display on the intelligent tester II.

PROBLEM SYMPTOMS TABLE
If a normal system code is displayed during the DTC check but the problem still occurs, check the circuits
for each problem symptom in the order given in the table below and proceed \
to the relevant troubleshooting
page.
HINT:
Inspect the ”Fuse” and ”Relay” before confirming the suspected area\
s as shown in the chart below.
Inspect each malfunction circuit in numerical order for the correspondin\
g symptom.
