STEP 1. Check the wiring harness between joint connector
(CAN2) C-04 and ETACS-ECU connector C-301 for a short
to ground. Measure the resistance at joint connector
(CAN2) C-04.
(1) Disconnect joint connector (CAN2), and measure the

resistance at the wiring harness side of joint connector
(CAN2).

(2) Measure the resistance between joint connector (CAN2)

terminal 6 and body ground.

OK: 1 k

Ω or more

(3) Measure the resistance between joint connector (CAN2)

terminal 19 and body ground.

OK: 1 k

Ω or more

Q: Do all the resistances measure 1 k

Ω or more?

YES <vehicles with ASC> : Go to Step 2.
YES <vehicles without ASC (FWD)> : Go to Step 5.
YES <vehicles without ASC (Electric controlled AWD)> :

Go to Step 3.

NO : Go to Step 11.
