P1767 HIGH AND LOW REVERSE CLUTCH SOLENOID

P1767 HIGH AND LOW REVERSE CLUTCH SOLENOID

Description

INFOID:0000000007357241

High and low reverse clutch solenoid valve is controlled by the TCM in response to signals sent from the trans-

mission range switch, output speed sensor and accelerator pedal position sensor (throttle position sensor).

Gears will then be shifted to the optimum position.

CONSULT Reference Value in Data Monitor Mode

INFOID:0000000007357242

On Board Diagnosis Logic

INFOID:0000000007357243

• This is an OBD-II self-diagnostic item.

• Diagnostic trouble code “P1767” with CONSULT or 8th judgment flicker without CONSULT is detected under

the following conditions.

- When TCM detects an improper voltage drop when it tries to operate the solenoid valve.

- When TCM detects as irregular by comparing target value with monitor value.

Possible Cause

INFOID:0000000007357244

• Harness or connectors

(The solenoid circuit is open or shorted.)

• High and low reverse clutch solenoid valve 

DTC Confirmation Procedure

INFOID:0000000007357245

CAUTION:

Always drive vehicle at a safe speed.

NOTE:

If “DTC Confirmation Procedure” has been previously performed, always turn ignition switch “OFF”

and wait at least 10 seconds before performing the next test.

After the repair, perform the following procedure to confirm the malfunction is eliminated.

 WITH CONSULT

1. Turn ignition switch “ON”. (Do not start engine.)

2. Select “DATA MONITOR” mode for “TRANSMISSION” with CONSULT.

3. Start engine.

4. Drive vehicle and maintain the following conditions for at least 5 consecutive seconds.

ACCELE POSI: 1.5/8 - 2.0/8

SLCT LVR POSI: “D” position 

GEAR: 2nd 

⇒

 3rd (HLR/C ON/OFF)

Driving location: Driving the vehicle uphill (increased engine load) will help maintain the driving

conditions required for this test.

5. If DTC is detected, go to 

TM-92, "Diagnosis Procedure"

.

 WITH GST

Follow the procedure “WITH CONSULT”.

Diagnosis Procedure

INFOID:0000000007357246

1.

CHECK INPUT SIGNAL

With CONSULT

1. Turn ignition switch ON.

2. Select “MAIN SIGNALS” in “DATA MONITOR” mode for “TRANSMISSION” with CONSULT.

3. Start the engine.

4. Read out the value of “HLR/C SOLENOID” while driving.

P1774 LOW COAST BRAKE SOLENOID

P1774 LOW COAST BRAKE SOLENOID

Description

INFOID:0000000007357253

• Low coast brake solenoid valve is turned “ON” or “OFF” by the TCM in response to signals sent from the

transmission range switch, output speed sensor and accelerator pedal position sensor (throttle position sen-

sor). Gears will then be shifted to the optimum position.

• This is not only caused by electrical malfunction (circuits open or shorted) but also by mechanical malfunc-

tion such as control valve sticking, improper solenoid valve operation.

CONSULT Reference Value in Data Monitor Mode

INFOID:0000000007357254

On Board Diagnosis Logic

INFOID:0000000007357255

• This is an OBD-II self-diagnostic item.

• Diagnostic trouble code “P1774” with CONSULT or 7th judgment flicker without CONSULT is detected under

the following conditions.

- When TCM detects that actual gear ratio is irregular, and relation between gear position and condition of

ATF pressure switch 2 is irregular during depressing accelerator pedal. (Other than during shift change)

- When TCM detects that relation between gear position and condition of ATF pressure switch 2 is irregular

during releasing accelerator pedal. (Other than during shift change)

Possible Cause

INFOID:0000000007357256

• Harness or connectors

(The solenoid and switch circuits are open or shorted.)

• Low coast brake solenoid valve 

• ATF pressure switch 2

P1815 M-MODE SWITCH

P1815 M-MODE SWITCH

Description

INFOID:0000000007357259

Instruction mode switch is installed in A/T shift selector. It sends instruction mode switch, shift up and shift down

switch signals to TCM.

TCM sends the switch signals to combination meter and A/C amp. by CAN communication line. Then instruction

mode switch position is indicated on the A/T position indicator.
