DESCRIPTIONS OF MONITOR METHODS
After reverse gear is achieved for 2 seconds, the engine runup*1 is detected for 2 seconds.
*1: The actual gear ratio deviates from the target gear ratio to the high engine (turbine) speed.

LOGIC FLOW CHARTS (Monitor Sequence)
DTC SET CONDITIONS
Check Conditions
- Shift stage: reverse gear.

PROBABLE CAUSES
- Transaxle assembly powertrain parts failure
- When the DTC P0715: Input shaft speed sensor system is stored
- When the DTC P0720: Output shaft speed sensor system is stored
- When the DTC P0962, P0963: Line pressure linear solenoid valve system is stored
- When the DTC P0979, P0980: 3-5 reverse clutch linear solenoid valve system is stored
- When the DTC P099B, P099C: Low-reverse brake shift solenoid valve system is stored
- When the DTC P2763, P2764: Lock-up and Low-reverse brake linear solenoid valve system is stored
- Malfunction of the 3-5 reverse clutch
- Malfunction of the low-reverse brake
- Malfunction of the valve body assembly
