INSPECT SHIFT SOLENOID VALVE SR
DTC P0985 Shift Solenoid "E" Control Circuit Low (Shift Solenoid Valve SR) |
DTC P0986 Shift Solenoid "E" Control Circuit High (Shift Solenoid Valve SR) |
DESCRIPTION
Shifting from 1st to 5th is performed in combination with the ON and OFF operation of the shift solenoid valves SL1, SL2, SL3, S4 or SR, which are controlled by the ECM. If an open or short circuit occurs in any of the shift solenoid valves, the ECM controls the remaining normal shift solenoid valves to allow the vehicle to be operated safely (RAV4_ACA30 RM000000O8L0BDX.html).DTC No.
| DTC Detection Condition
| Trouble Area
|
P0985
| ECM detects short in solenoid valve SR circuit 2 times when solenoid valve SR is operated (1 trip detection logic)
| - Short in shift solenoid valve SR circuit
- Shift solenoid valve SR
- ECM
|
P0986
| ECM detects open in solenoid valve SR circuit 2 times when solenoid valve SR is not operated (1 trip detection logic)
| - Open in shift solenoid valve SR circuit
- Shift solenoid valve SR
- ECM
|
MONITOR DESCRIPTION
The ECM commands gear shifts by turning the shift solenoid valves ON/OFF. When there is an open or short circuit in any shift solenoid valve circuit, the ECM detects the problem and illuminates the MIL and stores the DTC. And the ECM performs the fail-safe function and turns the other normal shift solenoid valves ON/OFF. In case of an open or short circuit, the ECM stops sending current to the circuit (RAV4_ACA30 RM000000O8L0BDX.html).

- Standard resistance:
Tester Connection
| Condition
| Specified Condition
|
9 (SR) - Body ground
| 20°C (68°F)
| 11 to 15 Ω
|
| 2.CHECK HARNESS AND CONNECTOR (TRANSMISSION WIRE - ECM) |
Connect the transmission wire connector.
Disconnect the ECM connector.
Measure the resistance according to the value(s) in the table below.
- Standard resistance:
Tester Connection
| Condition
| Specified Condition
|
B96-8 (SR) - Body ground
| 20°C (68°F)
| 11 to 15 Ω
|
| | REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
|
| 3.INSPECT SHIFT SOLENOID VALVE SR |
Remove the shift solenoid valve SR.
Measure the resistance between the solenoid valve terminal and solenoid valve body.
- Standard resistance:
Tester Connection
| Condition
| Specified Condition
|
Solenoid Connector (SR) - Solenoid Body (SR)
| 20°C (68°F)
| 11 to 15 Ω
|
Connect the battery's positive (+) lead to the terminal of the solenoid valve connector, and the negative (-) lead to the solenoid body. Then check that the valve moves and makes an operating sound.
- OK:
- Valve moves and makes operating sound.
