CVT
23A-50
.
DIAGNOSTIC FUNCTION
TCM determines that the malfunction is present
when the primary pulley speed sensor value
changes abruptly or when there is a discrepancy
between this sensor and other sensors in sensor
reading.
.
DESCRIPTIONS OF MONITOR METHODS
• The status with the secondary pulley speed of
500 r/min or more and with the primary pulley
speed of 150 r/min or less continues for 5 sec-
onds.
• When the primary pulley speed has dropped
abruptly from 1,000 r/min or more to 300 r/min or
less, and then it keeps 300 r/min or less for 0.5
seconds continuously.
.
MONITOR EXECUTION
• Transmission range: D
• Throttle valve opening : 1/8 or more
• Engine speed : 450 r/min or more
.

DTC SET CONDITIONS
Check Conditions
• Transmission range switch position: D.
• Secondary pulley speed: 500 r/min or more.
• Primary pulley speed at 10 millisecond before:
1,000 r/min or more.
• Throttle position sensor voltage: 1.37 volts or
more.
• Engine speed: 450 r/min or more.
• Voltage of battery: 9 volts or more.
• Voltage of battery: 16 volts or less.
JUDGMENT CRITERIA
• Primary pulley speed [secondary pulley speed:
1000 r/min or more]: 300 r/min or less. (5 sec-
onds)
• Primary pulley speed [Primary pulley speed at 10
millisecond before: 1,000 r/min or more]: 300
r/min or less. (0.5 second)
.
OBD-II DRIVE CYCLE PATTERN
Transmission range: D (Drive the vehicle for 20 sec-
onds or more while the accelerator opening angle is
20% or more)
.
PROBABLE CAUSES
• Malfunction of primary pulley speed sensor
• Damaged wiring harness and connectors
• Malfunction of TCM
DIAGNOSTIC PROCEDURE
STEP 1. M.U.T.-III data list
Item 1: Primary speed sensor signal (Refer to Data List Refer-
ence Table
Q: Is the check result normal?
YES : Intermittent malfunction
NO : Go to Step 2.
STEP 2. Check the following connector:
• B-126 Primary pulley speed sensor connector
• C-37 TCM connector
• A-12 Intermediate connector
Check the terminals for a contact status problem and internal
short circuit.
Q: Is the check result normal?
YES : Go to Step 3.
NO : Repair the defective connector.
STEP 3. Check for open circuit in the wiring harness
between the primary pulley speed sensor connector and
the TCM connector
Between B-126 primary pulley speed sensor connector (termi-
nal No.3) and C-37 TCM connector (terminal No.48)
Q: Is the check result normal?
YES : Go to Step 4.
NO : Repair the wiring harness.
