9.3.6 Diagnostic information and procedures

9.3.6.1 Visual inspection

-

Confirm Fault Symptom

The most difficult situation in troubleshooting is that there is no any symptom incurred. In this case, it is necessary
to analyze the fault described by the user thoroughly. Then simulate the failure with the customer vehicle.

The same or similar condition and environment. No matter how rich the experience of the maintenance personnel
is and no matter how skilled the technology is, troubleshoot if not confirming the symptom, it will during repair

Ignore something important, and make wrong guess in some places. It may cause that the troubleshooting is
unable to be done.

-

Inspect components easy to access system to identify whether there is a significant damage that may lead to
the fault.

-

Support of connector joint and completely check main part for vibration, if vibration may caused fault
condition, suggest vibration method

1. With a finger, gently shook the part that may be faulty and inspect for malfunction.

2. Gently shake the connector vertically and horizontally.

3. Slightly shake wire harness in vertical and horizontal direction.

-

On-board inspection

A. Check the driver seat belt warning lamp;

a. Turn the ignition switch to the ON position.

b. When the driver seat belt is unfastened, check whether the driver seat belt warning lamp on the combination

instrument flickers.

c. When the driver seat belt is fastened, check whether the driver seat belt warning lamp on the combination

instrument goes out.

B. Check the passenger seat belt warning lamp:

a. Turn the ignition switch to the ON position.

b. If the passenger's seat is occupied and the seat belt is not fastened, check whether the passenger seat belt

warning lamp on the multi-functional instrument indicator flickers.

c. If the passenger seat is occupied and the seat belt is fastened, check whether the passenger seat belt warning

lamp on the multi-functional instrument indicator goes out.

Diagnostic Steps:

1

Inspect the passenger seat safety belt buckle assembly.

(a) Disconnect driver seal safety belt lock catch

harness connector SO13.

(b) Use multimeter to measure whether driver's side

seat safety belt switch status meets the following
requirements.

(c) Tie safety belt, resistance between terminal 1 and

2 is 10kΩ or higher.

(d) When disconnect safety belt, resistance between

terminal 1 and 2 is lower than 1Ω.

Confirm if the resistance conforms to standard value.
