Acura RL. Manual - part 47

MONITOR DESCRIPTION CHART 

Enable Conditions 

ENABLE CONDITIONS 

Malfunction Threshold 

The transmission is held in 5th gear against the 3rd gear command for at least 1.5 seconds. 

Driving Pattern 

Start the engine, and accelerate the vehicle until the transmission shifts into 5th gear in the D position. 



Drive the vehicle in this manner only if the traffic regulations and ambient conditions allow.  

Diagnosis Details 

Conditions for illuminating the MIL 

When a malfunction is detected during the first drive cycle, a Temporary DTC is stored in the PCM 
memory. If the malfunction recurs during the next (second) drive cycle, the MIL comes on and the DTC and 
the freeze frame data are stored. 

Conditions for clearing the MIL 

The MIL will be cleared if the malfunction does not recur during three consecutive trips in which the 
diagnostic runs. 

The MIL, the DTC, the Temporary DTC, and the freeze frame data can be cleared by using the scan tool 
Clear command or by disconnecting the battery.

General Description 

Shift solenoid valve A is installed in the transmission housing. It is controlled by the ON/OFF signal from 
the powertrain control module (PCM) to apply line pressure to shift valve A. The signal from the PCM is 
output to apply clutch pressure control pressure to the proper gear change clutch according to the gear 
change schedule. When the signal to shift solenoid valve A from the PCM is OFF, and line pressure is 
discharged, shift valve A is inactive. When the signal to shift solenoid valve A from the PCM is ON, and 
line pressure is applied to shift valve A, it operates against the shift valve A spring. The PCM monitors the 
transmission fluid switch at the speed change stage determined by the shift schedule. When the wrong 
transmission fluid switch is turned on for a given speed change mode, a shift solenoid valve turn-on 
malfunction is detected and a DTC is stored.
