DIAGNOSTIC PROCEDURE

Step 1. Connector check: C-217 ETACS-ECU
connector

Q: Is the check result normal?

YES :

Go to Step 2.

NO :

Repair the defective connector.

Step 2. Measure the voltage at the C-217
ETACS-ECU connector.

(1) Remove the ETACS-ECU, and measure at the

junction block side.

(2) Voltage between C-217 ETACS-ECU connector

terminal No.20 and body earth.

OK: System voltage

Q: Is the check result normal?

YES :

Go to Step 4.

NO :

Go to Step 3.

SYMPTOM PROCEDURES

SMART WIRING SYSTEM (SWS) NOT USING SWS MONITOR

54B-56

Prior to the wiring harness inspection, check
intermediate connector C-116, joint connector C-02
and junction block connector C-202, and repair if
necessary.

•

Check the power supply line for open circuit.

Q: Is the check result normal?

YES :

The trouble can be an intermittent

malfunction (Refer to GROUP 00

−

How to

Cope with Intermittent Malfunction

P.00-6

).

NO :

Repair the wiring harness.

Step 4. Measure the resistance at the C-217
ETACS-ECU connector.

(1) Remove the ETACS-ECU, and measure at the

junction block side.

(2) Continuity between C-217 ETACS-ECU

connector terminal No.3 and body earth.

OK: 2

Ω

or less

Q: Is the check result normal?

YES :

Go to Step 6.

NO :

Go to Step 5.
