TROUBLESHOOTING

PRIOR TO TROUBLESHOOTING

M1549014700431

Before carrying out troubleshooting, check the 
following two items.

•

Make sure that the ETACS-ECU, the junction 
block (J/B), the front-ECU and the engine 
compartment relay box are connected securely.

•

Check that the system fuses and fusible links are 
not burned out.

DIAGNOSTIC FUNCTION

M1549028900115

How to read diagnosis code

Use the MUT-II/III to read diagnosis code (Refer to 
GROUP 00 

−

 How to Use 

Troubleshooting/Inspection Service Points 

P.00-6

.)

NOTE: Connect the MUT-II/III to the 16-pin diagnosis 
connector (black).
NOTE: A diagnosis code can not be read when the 
ETACS-ECU is defective or the power supply voltage 
has risen. In this case, refer to inspection procedure 
A-1 "Communication with the MUT-II/III is not 
possible 

P.54B-48

."

How to check input signals

1. Use the MUT-II/III or a voltmeter to check input 

signals (Refer to GROUP 00 

−

 How to Use 

Troubleshooting/Inspection Service Points 

P.00-6

.)

2. The input signals below can be checked by 

connecting the MUT-II/III or a voltmeter to the 
diagnosis connector.

NOTE: If a fault is found at the input signal check, 

refer to trouble symptom chart 

P.54B-45

.
