DTC P1767 HIGH AND LOW REVERSE CLUTCH SOLENOID VALVEPFP:31940
DescriptionECS00G0Q
High and low reverse clutch solenoid valve is controlled by TCM in response to signals sent from PNP switch,
vehicle speed sensor and accelerator pedal position sensor. Gears will then be shifted to the optimum posi-
tion.
CONSULT-II Reference ValueECS00G0R
On Board Diagnosis LogicECS00G0S
Diagnostic trouble code “P1767 HLR/C SOL/CIRC” with CONSULT-II or 8th judgement flicker without CON-
SULT-II is detected under the following conditions.
lWhen TCM detects an improper voltage drop when it tries to operate the solenoid valve.
lWhen TCM detects as irregular by comparing target value with monitor value.
Possible CauseECS00G0T
lHarness or connectors
(The solenoid circuit is open or shorted.)
lHigh and low reverse clutch solenoid valve
DTC Confirmation ProcedureECS00G0U
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-II
1. Turn ignition switch ON. (Do not start engine.)
2. Select “MAIN SIGNALS” in “DATA MONITOR” mode for “A/T”
with CONSULT-II.
3. Touch “START”.
4. Start engine.
5. 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: “2”
“3” (HLR/C ON/OFF)
Driving location: Driving the vehicle uphill (increased
engine load) will help maintain the driving conditions required for this test.
6. If DTC is detected, go toAT- 1 4 8 , "
Diagnostic Procedure".
WITHOUT CONSULT-II

DescriptionECS00G0W
lHigh and low reverse clutch solenoid valve is controlled by TCM in response to signals sent from PNP
switch, vehicle speed sensor and accelerator pedal position sensor. Gears will then be shifted to the opti-
mum position.
lThis is not only caused by electrical malfunction (circuits open or shorted) but also by mechanical mal-
function such as control valve sticking, improper solenoid valve operation.
