DIAGNOSIS

TSB Revision

CONTROLLER AREA NETWORK (CAN)

54C-407

STEP 7. Check the CAN bus lines (communication line 
only) between intermediate connector C-29 and joint 
connector (3). Measure the resistance at intermediate 

connector C-29 and 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 intermediate 

connector C-29, and measure the resistance between the 
wiring harness side connector of joint connector (3) C-02 
and the female side connector of intermediate connector 
C-29 (instrument panel wiring harness side).

(2) Turn the ignition switch to the "LOCK" (OFF) position.

CAUTION

Disconnect the negative battery terminal. For details refer 
to 

P.54C-4

.

(3) Disconnect the negative battery terminal.

(4) Measure the resistance between intermediate connector 

terminal 12 and joint connector (3) terminal 20.

OK: 2 ohms or less

(5) Measure the resistance between intermediate connector 

terminal 11 and joint connector (3) terminal 9.

OK: 2 ohms or less

CAUTION

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

P.54C-5

.

Q: Do all the resistances measure 2 ohms or less?

YES : If all the resistances measure 2 ohms or less, go to 

Step 2.

NO :  If either of the resistances measures more than 2 

ohms or all the resistances measure more than 2 
ohms, repair the wiring harness between joint 
connector (3) and the intermediate connector, and 
then go to Step 2.

54C-409

STEP 8. Check the front wiring harness side CAN bus lines 
(communication line including the powertrain control 
module). Measure the resistance at intermediate connector 

C-29.

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 intermediate connector C-29, and measure the 

resistance at the male side (at front wiring harness side).

(2) Turn the ignition switch to the "LOCK" (OFF) position.

CAUTION

Disconnect the negative battery terminal. For details refer 
to 

P.54C-4

.

(3) Disconnect the negative battery terminal.

(4) Measure the resistance between intermediate connector 

terminals 11 and 12.

OK: 120 

± 20 

Q: Does the resistance measure 120 

± 20 ?

YES : If the resistance measures 120 

± 20 Ω, go to Step 12.

NO :  If the resistance does not measure 120 

± 20 Ω, go to 

Step 9 .
