STEP 5. Check the wiring harness between joint connector
(CAN3) C-01 and ECM connector B-11 for a short to power
supply. Measure the voltage at joint connector (CAN3)
C-01.
(1) Disconnect joint connector (CAN3), and measure the

voltage at the wiring harness side of joint connector
(CAN3).

(2) Turn the ignition switch to the ON position.
(3) Measure the voltage between joint connector (CAN3)

terminal 4 and body ground.

OK: 4.7 volts or less

(4) Measure the voltage between joint connector (CAN3)

terminal 15 and body ground.

OK: 4.7 volts or less

Q: Do all the voltages measure 4.7 volts or less?

YES : Go to Step 6.
NO : Go to Step 12.

STEP 6. Check the wiring harness between joint connector
(CAN3) C-01 and ABS-ECU connector A-01 <vehicles
without ASC> or ASC-ECU connector A-02 <vehicles with
ASC> for a short to power supply. Measure the voltage at
joint connector (CAN3) C-01.
(1) Disconnect joint connector (CAN3), and measure the

voltage at the wiring harness side of joint connector
(CAN3).

(2) Turn the ignition switch to the ON position.
(3) Measure the voltage between joint connector (CAN3)

terminal 6 and body ground.

OK: 4.7 volts or less

(4) Measure the voltage between joint connector (CAN3)

terminal 19 and body ground.

OK: 4.7 volts or less

Q: Do all the voltages measure 4.7 volts or less?

YES <CVT, A/T> : Go to Step 7.
YES <M/T> : Check intermediate connector C-33, and

repair if necessary. If the intermediate connector is in
good condition, repair the wiring harness between
joint connector (CAN2) C-04 and joint connector
(CAN3) C-01.

NO : Go to Step 13.

STEP 7. Check the wiring harness between joint connector
(CAN3) C-01 and TCM connector C-38 for a short to power
supply. Measure the voltage at joint connector (CAN3)
C-01.
(1) Disconnect joint connector (CAN3), and measure the

voltage at the wiring harness side of joint connector
(CAN3).

(2) Turn the ignition switch to the ON position.
(3) Measure the voltage between joint connector (CAN3)

terminal 7 and body ground.

OK: 4.7 volts or less

(4) Measure the voltage between joint connector (CAN3)

terminal 20 and body ground.

OK: 4.7 volts or less

Q: Do all the voltages measure 4.7 volts or less?

YES : Check intermediate connector C-27, and repair if

necessary. If the intermediate connector is in good
condition, repair the wiring harness between joint
connector (CAN2) C-04 and joint connector (CAN3)
C-01.

NO : Go to Step 14.

STEP 8. Using scan tool MB991958, diagnose the CAN bus
line. (checking the steering wheel sensor for internal short
to ground)

CAUTION

Strictly observe the specified wiring harness repair proce-
dure. For details refer to

P.54C-7

.

CAUTION

To prevent damage to scan tool MB991958, always turn the
ignition switch to the "LOCK" (OFF) position before con-
necting or disconnecting scan tool MB991958.
(1) Disconnect steering wheel sensor connector C-209.
(2) Connect scan tool MB991958 to the data link connector.
(3) Turn the ignition switch to the "ON" position.

(4) Diagnose CAN bus lines, and check if the scan tool

MB991958 screen is as shown in the figure.

OK: The display of the scan tool MB991958 is as
shown in the figure.

Q: Does scan tool MB991958 screen correspond to the

illustration?
YES : Repair the wiring harness between steering wheel

sensor connector C-209 and joint connector (CAN2)
C-04.

NO : Check steering wheel sensor connector C-209, and

repair if necessary. If the steering wheel sensor
connector is in good condition, replace the steering
wheel sensor.
