6.
CHECK CIRCUIT BETWEEN IPDM E/R AND PRIMARY SPEED SENSOR (PART 1)
1. Disconnect IPDM E/R connector.
2. Check continuity between IPDM E/R harness connector terminal and primary speed sensor harness con-
nector terminal.
Is the check result normal?
YES
>> GO TO 7.
NO
>> Repair or replace malfunctioning parts.
7.
CHECK CIRCUIT BETWEEN IPDM E/R AND PRIMARY SPEED SENSOR (PART 2)
Check continuity between IPDM E/R harness connector terminal and ground.
Is the check result normal?
YES
>> GO TO 8.
NO
>> Repair or replace malfunctioning parts.
8.
DETECT MALFUNCTIONING ITEMS
Check the following items:
• Harness open circuit or short circuit between ignition switch and IPDM E/R. Refer to
gram — Ignition Power Supply —"
• 10A fuse (No.49, IPDM E/R). Refer to
PG-62, "IPDM E/R Terminal Arrangement"
• IPDM E/R
Is the check result normal?
YES
>> Check intermittent incident. Refer to
GI-45, "Intermittent Incident"
.
NO
>> Repair or replace malfunctioning parts.

DTC CONFIRMATION PROCEDURE
CAUTION:
Be careful of the driving speed.
1.
PREPARATION BEFORE WORK
If another "DTC CONFIRMATION PROCEDURE" occurs just before, turn ignition switch OFF and wait for at
least 10 seconds, then perform the next test.
>> GO TO 2.
2.
CHECK DTC DETECTION
1. Start the engine.
2. Drive the vehicle.
3. Maintain the following conditions for 10 seconds or more.
4. Stop the vehicle.
5. Check the first trip DTC.
Is “P0720” detected?
YES
>> Go to
NO

Output Speed Sensor Circuit
The output speed sensor value is less than
150 rpm continuously for 10 seconds or more
under the following diagnosis conditions:
• Diagnosis conditions
- Selector lever: “D”, “L” or “R” position
- Auxiliary gearbox shifting is not in progress.
- When the “D” position switch, “L” position
switch or “R” position switch is ON, the out-
put speed has not experienced 250 rpm or
more.
- After shifting the selector lever, the input
speed has experienced less than 300 rpm.
- Secondary pulley speed: 1,500 rpm or more
- TCM power supply voltage: More than 11 V
• Harness or connector
(Output speed sensor circuit is open or
shorted)
• Output speed sensor
The output speed sensor value is 90 rpm or
less continuously for 500 msec or more under
the following diagnosis conditions:
• Diagnosis conditions
- 10-msec-ago output speed: 730 rpm or
more
- TCM power supply voltage: More than 11 V
Selector lever
: “D” position
Vehicle speed
: 55 km/h (34 MPH) or more
