DTC Confirmation Procedure INFOID:0000000004666922
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If “DTC Confirmation Procedure” has been previously performed, alw ays turn ignition switch OFF and
wait at least 10 seconds before performing the next test.
After the repair, touch “ERASE” on “SELF-DIAG RESU LTS” and then perform the following procedure to con-
firm the malfunction is eliminated.

DTC P0730 BELT DAMAGE
Description INFOID:0000000004666954
TCM selects the gear ratio using the engine load (throttle position), the primary pulley revolution speed, and
the secondary pulley revolution speed as input signal. T hen it changes the operating pressure of the primary
pulley and the secondary pulley and changes the groove width of the pulley.

• This is not an OBD-II self-diagnostic item.
• TCM calculates the actual gear ratio with input speed sensor (primary speed sensor) and output speed sen-
sor (secondary speed sensor).
• Diagnostic trouble code “P0730 BELT DAMG” with CONSUL T-III is detected, when TCM receives an unex-
pected gear ratio signal.
