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?
YES
>> Check intermittent incident. Refer to
GI-41, "Intermittent Incident"
.
NO
>> Repair or replace malfunctioning parts.

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
