Acura RL. Manual - part 49

Malfunction Threshold 

One of these conditions occurs. 



The 2nd clutch transmission fluid switch is ON against the 3rd --> 4th gear upshift command for at 
least 11 seconds.  



After the 3rd --> 4th gear upshift command is output, neutral is indicated when the 5th gear shift 
command is output for at least 2 seconds, though there is no record of being in neutral.  

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.

Fig. 152: Shift Solenoid Valve Driving Signal Combination Table 

General Description 

Shift solenoid valve C 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 C. 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 C from the PCM is ON, and line pressure is 
discharged, shift valve C is inactive. When the signal to shift solenoid valve C from the PCM is OFF, and 
line pressure is applied to shift valve C, it operates against the shift valve C spring. The PCM monitors the 
input shaft (mainshaft) speed and the output shaft (countershaft) speed at the gear change determined by the 
shift schedule. When an improper gear ratio is output compared to the predetermined gear change mode, a 
shift solenoid valve C OFF failure is detected and a DTC is stored.

Malfunction Threshold 

One of these symptoms occurs with the record that the actual gear position was neutral when the 1st gear 
shift is commanded: 



The transmission is held in 2nd gear against the 2nd --> 3rd gear upshift command for as long as 20 
seconds.  



The transmission is held in 4th gear against the 4th --> 5th gear upshift command for as long as 20 
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.
