Acura RL. Manual - part 65

 

 

Driving Pattern 

Start the engine, and drive the vehicle in 1st gear in the D position for at least 1 second. 

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, the MIL comes on and the DTC and the freeze frame data are stored in the 
PCM memory. 

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

Fig. 216: Shift Solenoid Valve Driving Signal Combination Table 

General Description 

When shift solenoid valves A and D are turned ON, the hydraulic pressure circuit opens. When shift 
solenoid valves B and C are turned OFF, the hydraulic pressure circuit opens. The hydraulic pressure circuit 
supplies/discharges hydraulic pressure to/from each clutch according to the combination of the ON/OFF 
status of those valves and the shift valves. The powertrain control module (PCM) commands the driver 
circuit to turn on the shift solenoid valve. The circuit diagnoses malfunctions such as a circuit short or open, 
and sends back a return signal during the PCM's command. A malfunction is detected when the return signal 
does not match the PCM command to turn OFF the shift solenoid valve, and a DTC is stored.
