supply. These DTC can be cleared by removing the
specified TCM connector for at least two minutes.

Remove the TCM connector (B56) for at least
two minutes.
 TCM connector (B56) is located in the line to

10.Power Indicator Light Display
A: OPERATION
When any on-board diagnostics item is malfunctioning, the display on POWER indicator light blinks from the
time malfunction is detected after starting the engine until ignition switch is turned to OFF. The malfunctioning
part or unit can be determined by a DTC during on-board diagnostics operation. Problems which occurred
previously can also be identified through the memory function. If the Power indicator does not show a prob-
lem (although a problem is occurring), the problem can be determined by checking the performance charac-
teristics of each sensor using select monitor. The indicator signal is as shown in the figure.
Perform the inspection when the POWER indicator light does not operate correctly. INSPECTION, Power Indicator Light Display.>
