54C-163

STEP 47. Check the CAN_L line (communication line 
including the multi-center display unit (middle-grade type)) 
between joint connector (3) and middle-grade multi-center 
display connector for a short to the power supply. Measure 

the voltage at joint connector (3) C-02.

CAUTION

A digital multimeter should be used. For details refer to 

P.54C-4

.

CAUTION

The test wiring harness should be used. For details refer to 

P.54C-4

.

(1) Disconnect joint connector (3) C-02, and measure the 

voltage at the wiring harness side of joint connector (3) 
C-02.

(2) Turn the ignition switch to the "ON" position.

(3) Measure the voltage between joint connector (3) terminal 

19 and body ground.

OK: 4.0 V or less

Q: Does the voltage measure 4.0 V or less?

YES : If the voltage measures 4.0 V or less, go to Step 50.
NO :  If the voltage measures more than 4.0 V, go to Step 

48.

STEP 48. Check multi-center display unit (middle-grade 
type) connector C-05 for loose, corroded or damaged 
terminals, or terminals pushed back in the connector.

CAUTION

The strand end of the twisted wire should be within 10 cm 
(4 inches) from the connector. For details refer to 

P.54C-4

.

Q: Is multi-center display unit (middle-grade type) 

connector C-05 in good condition?
YES : 
Go to Step 49.
NO :  Repair the damaged parts.

STEP 49. Check the CAN_L line (communication line only) 
between joint connector (3) and multi-center display unit 
(middle-grade type) connector for a short to the power 

supply. Measure the voltage at joint connector (3) C-02.

.

(1) Disconnect joint connector (3) C-02 and multi-center display 

unit (middle-grade type) connector C-05, and measure the 

voltage at the wiring harness side of joint connector (3) 
C-02.

(2) Turn the ignition switch to the "ON" position.

(3) Measure the voltage between joint connector (3) terminal 

19 and body ground.

OK: 1.0 V or less

CAUTION

Strictly observe the specified wiring harness repair proce-
dure. For details refer to 

P.54C-5

.

Q: Does the voltage measure 1.0 V or less?

YES : If the voltage measures 1.0 V or less, diagnose CAN 

bus lines thoroughly by referring to 

P.54C-534

.

NO :  If the voltage measures more than 1.0 V, repair the 

wiring harness between joint connector (3) and the 
multi-center display unit (middle-grade type) 
connector.
