Use the following steps to easily route antenna feeder cable
in the event of installation:
1. Tie string at the top end of feeder cable.
2. Pull out feeder cable until pipe end of antenna base is visible.
3. Insert string into the hole at pipe end of antenna base,
and wrap vinyl tape on the string.
Caution
Tape should be wrapped so that the string cannot
be removed.
4. Gradually pull out remove antenna base.

CHASSIS ELECTRICAL -Defogger54A-43
ON-VEHICLE SERVICE
PRINTED HEATER CHECK
(1) With engine running at 2,000 rpm and battery in charging
mode, check print heater for normal operation.
(2) With defogger switch in “ON” position, use circuit tester
to measure voltage of individual print heaters at the center
point A of rear window glass. When the tester indicates
approx. 6V, the print heater is evaluated normal.
(3) When the measured value at Position A is 12V, open
circuit occurs between Position A and minus terminal.
In this case, carefully move test bar to minus terminal
side to detect a rapid voltage drop point (0V). This voltage
drop point indicates open circuit section.
(4) When voltage at Position A is 0V, open circuit occurs
between Position A and plus terminal. According to the
previous step, detect a rapid voltage increase point (12V).

TROUBLESHOOTING
BEFORE COMMENCING TROUBLESHOOTING
Before starting troubleshooting, check the following two points to ensure there are no defects.
DCheck the state of the connector couplings to the ETACS-ECU and junction box.
DCheck that the fuses and fusible links relating to all systems are not fused.
STANDARD FLOW OF DIAGNOSTIC TROUBLESHOOTING
Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points.
DIAGNOSTIC FUNCTIONS
READING DIAGNOSIS CODES
Read the diagnosis codes using MUT-II. (Refer to GROUP 00 - How to Use Troubleshooting/Inspection
Service Points.)
NOTE
1. Connect MUT-II to the 16-pin diagnosis connector (black).
2. The diagnosis code cannot be read when there is an ETACS-ECU fault or when the power is first
turned ON (voltage rising). In this case, refer to “No Communication with MUT-II” (P. 54B-10) on
Fault Symptom Inspection Procedure, and perform troubleshooting.

SWS -Troubleshooting54B-3
INPUT SIGNAL CHECK
1. Check the inputs using MUT-II or a voltmeter. (Refer to GROUP 00 - How to Use
Troubleshooting/Inspection Service Points.)
2. The following input signals can be checked using MUT-II or a voltmeter connected to the diagnosis
connector.
NOTE
When fault is detected during input signal inspection, refer to Trouble Symptom Chart to perform
troubleshooting. (Refer to P.54B-7).
Input Signal Check Function
