gram — Ignition Power Supply —"

 .

• Short circuit in harness between IPDM E/R harness connector terminal 21 and primary speed sensor har-

ness connector terminal 3.

• 10A fuse (No.49, IPDM E/R). Refer to 

PG-60, "IPDM E/R Terminal Arrangement"

.

• IPDM E/R
Is the check result normal?

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

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
