OBD-II DRIVE CYCLE PATTERN
Start the engine, and drive for 5 seconds, with 1st gear
fixed (1st gear in sport mode), at more than 20 km/h
(12  mph)  with  more  than  50%  of  throttle  valve
opening. Then stop the vehicle, and drive again for 5

seconds, with 1st gear fixed (1st gear in sport mode),
at more than 20 km/h (12 mph) with more than 50%
of throttle valve opening.

TROUBLESHOOTING HINTS (THE MOST LIKELY
CAUSES FOR THIS CODE TO BE SET ARE:)

｠

Malfunction  of  the  output  shaft  speed  sensor
system circuit

｠

Damaged harness or connector

｠

Malfunction of the output shaft speed sensor

｠

Malfunction of the TCM

｠

Malfunction of the output shaft speed sensor rotor
(A/T assembly)

 

DIAGNOSIS

STEP 1. Check the TCM terminal voltage and frequency.
[C-37 TCM connector (vehicle side, connected)]

23A-44

AUTOMATIC TRANSAXLE MECHANICAL

AUTOMATIC TRANSAXLE DIAGNOSIS

Check that the voltage between C-37 terminal No. 48 and C-38
terminal No. 13 or C-38 terminal No. 26 is 0 V, and then check
the frequency of C-37 terminal No. 37.

｠

At D range, vehicle speed is 30 km/h (19 mph): Approx. 588
Hz

Q:Is the check result normal?

YES:

 Go to Step 6.

NO:

 Go to Step 2.

STEP 2. Check the power supply and sensor ground.
[B-108  output  shaft  speed  sensor  connector  (vehicle  side,
disconnected)]

｠

With the ignition switch ON: Terminal No. 1 to No. 3 → Battery
positive voltage

Q:Is the check result normal?

YES:

 Go to Step 3.

NO:

 Go to Step 4.

STEP 3. Check the wiring harness between the output shaft
speed sensor and TCM.
Check for continuity between B-108 output shaft speed sensor
terminals and C-37 TCM terminals.

｠

Between  B-108  terminal  No.  2  and  C-37  terminal  No.  37:
Continuity exists.

When the continuity check result is OK, check that the wiring
harness is not shorted to the body and other wiring harness.

Q:Is the check result normal?

YES:

 Replace the output shaft speed sensor with the one

of the same transaxle of the same model. Then go to Step
7.

NO:

 Repair or replace the failure section, and then go

to Step 6.

STEP 4. Check the path between the ignition switch and the
output shaft speed sensor.

｠

Check the wiring harness for an open/short circuit between the
ignition switch and B-108 output shaft speed sensor connector
terminal No. 1.

｠

Check for a blown fuse.

Q:Is the check result normal?

YES:

 Go to Step 5.

NO:

 Repair or replace the failure section.

STEP 5. Check the wiring harness between the output shaft
speed sensor and TCM.
Check for continuity between B-108 output shaft speed sensor
terminals and C-38 TCM terminals.

｠

Between  B-108  terminal  No.  3  and  C-37  terminal  No.  48:
Continuity exists.

When the continuity check result is OK, check that the wiring
harness is not shorted to the body and other wiring harness.

Q:Is the check result normal?

AUTOMATIC TRANSAXLE DIAGNOSIS

YES:

 Go to Step 8.

NO:

 Repair or replace the failure section.

STEP 6. Drive the vehicle for a while.
Check that the normal code is displayed.

Q:Is the check result normal?

YES:

 The procedure is complete.

NO:

 Replace the TCM.

STEP 7. After replacing the output shaft speed sensor, drive
the vehicle for a while, and then check the DTC again.

Q:Is the check result normal?

YES:

 Replace the output shaft speed sensor.

NO:

 Replace the TCM.

STEP 8. Check the TCM connector pin terminal and the
connection status.

Q:Is there a failure point?

YES:

 Repair or replace the failure section.

NO:

 Replace the TCM.
