STEP 3. Measure the voltage at engine-ECU
connector C-113 <M/T> or engine-A/T-ECU
connector C-113 <A/T>.
(1) Turn the ignition switch to the "ON" position and

the MAIN switch to the "OFF" position.

(2) Measure the voltage between engine-ECU

connector C-113 <M/T> terminal No.94 or
engine-A/T-ECU connector C-113 <A/T> terminal

No.94 and earth.

OK: 4.7

−5.0 V

(3) Turn the ignition switch to the "LOCK" (OFF)

position.

Q: Is the check result normal?

YES :

Go to Step 6.

NO :

Go to Step 4.

STEP 4. Connector check: C-113 engine-ECU
connector <M/T> or C-113 engine-A/T-ECU
connector <A/T>

Q: Is the check result normal?

YES :

Go to Step 5.

NO :

Repair or replace the faulty connector, and
install the air bag module (driver’s side)
(Refer to GROUP 52B, Driver’s, Front
Passenger’s Air Bag Module(s) and Clock
Spring

P.52B-225

). Then go to Step 18.

STEP 5. Check the harness between engine-ECU
connector C-113 <M/T> terminal No.94 or
engine-A/T-ECU connector C-113 <A/T> terminal
No.94 and the auto-cruise control switch
connector C-305 terminal No.2.

(1) Disconnect engine-ECU connector C-113 <M/T>

or engine-A/T-ECU connector C-113 <A/T> and

measure at the harness connector side.

(2) Turn the ignition switch to the "ON" position and

the MAIN switch to the "OFF" position.

(3) Measure the continuity between engine-ECU

connector C-113 <M/T> terminal No.94 or
engine-A/T-ECU connector C-113 <A/T> terminal
No.94 and earth.

(4) Turn the ignition switch to the "LOCK" (OFF)

position.

(5) Connect engine-ECU connector C-113 <M/T> or

engine-A/T-ECU connector C-113 <A/T>.

Q: Is the measured continuity open circuit?

YES :

Install the air bag module (driver’s side)

(Refer to GROUP 52B, Driver’s, Front
Passenger’s Air Bag Module(s) and Clock
Spring

P.52B-225

). Then go to Step 17.

NO :

Go to Step 6.
