Q: Is the check result normal?

YES <All the signals are received normally.> :

Go

to Step 4.

NO <The seat belt switch signal is not received.> :

Refer to inspection procedure C-6 "The seat
belt switch signal is not received

P.54A-544

<L.H. drive vehicles> or

P.54A-544

<R.H.

drive vehicles>."

NO <The ignition switch (IG1) signal is not
received.> :

Refer to inspection procedure C-3

"The ignition switch (IG1) signal is not
received

P.54A-533

."

STEP 4. Check the combination meter

Q: Does the combination meter work?

YES :

Go to Step 5.

NO :

Refer to symptom procedure 1 "Power
