CVT

23A-102

DIAGNOSTIC PROCEDURE

STEP 1. M.U.T.-III data list
Item 36: LU/SEL changeover SOL. output
Item 37: LU/SEL changeover SOL. monitor

OK: Check that the output and monitor do not differ 
greatly.

Q: Is the check result normal?

YES : Intermittent malfunction
NO :  Go to Step 2.

STEP 2. Check the following connector:

• B-125 CVT assembly connector

• C-38 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 and short to ground in the 
wiring harness between the TCM connector and the CVT 
assembly connector.
Between C-38 TCM connector (terminal No.14) and B-125 CVT 
assembly connector (terminal No.4)
Q: Is the check result normal?

YES : Go to Step 4.
NO :  Repair the wiring harness.

STEP 4. Lockup/select switching solenoid valve single unit 
check
Refer to 

P.23A-146

.

Q: Is the check result normal?

YES : Go to Step 5.
NO :  Replace the valve body assembly.

STEP 5. Symptom recheck after erasing diagnostic trouble 
code
Q: Is the check result normal?

YES : Intermittent malfunction
NO :  Replace TCM.

DTC P1745: Monitoring of Percentage Change in Pulley Ratio

.

DIAGNOSTIC FUNCTION

TCM conducts fault detection by monitoring the inter-
nal calculated value.

.

JUDGEMENT CRITERIA

Percentage change in pulley ratio is larger than the 
standard value.

.

PROBABLE CAUSES

• Malfunction of TCM

DIAGNOSTIC PROCEDURE

STEP 1. Symptom recheck after erasing diagnosis code
Q: Is the check result normal?

YES : Intermittent malfunction
NO :  Replace TCM.

DTC P1773: Malfunction of ABS

.

DIAGNOSTIC FUNCTION

TCM detects the ABS abnormality.

.

DESCRIPTIONS OF MONITOR METHODS

• When the ABS error signal reception continues 

for 0.5 seconds.

.

MONITOR EXECUTION

• When 1.05 seconds have elapsed after TCM 

started (not during M.U.T.-III communication)

.

MONITOR EXECUTION CONDITIONS 
(OTHER MONITOR AND SENSOR)

Other Monitor (There is no temporary DTC stored 

in memory for the item monitored below)

• Not applicable

Sensor (The sensor below is determined to be 

normal)

• Not applicable

DTC SET CONDITIONS

Check Conditions

• Time after TCM start: more than 1.05 seconds.

Judgment Criteria

• ABS status: malfunction

.

OBD-II DRIVE CYCLE PATTERN

Ignition switch : ON (start the engine and keep it for

cation)

.

PROBABLE CAUSES

• Malfunction of the ABS system

• Malfunction of TCM

DIAGNOSTIC PROCEDURE

STEP 1. ABS system DTC check
Q: Is the ABS system DTC set?
