INSPECTION PROCEDURE
1 INSPECT TRANSMISSION WIRE(SLT)
(a) Disconnect the transmission wire connector from the
transaxle.
(b) Measure the resistance between terminals SLT+ and
SLT±.
OK:
Resistance: 5.0 to 5.6 at 20
C (68

(c) Measure the resistance between terminals SLT+ and
SLT± of the transmission wire connector and body
ground.
OK:
Resistance: 1M or higher
NG Go to step 3

2 CHECK HARNESS AND CONNECTOR(TRANSMISSION WIRE ± ECM)
(a) Connect the transmission wire connector to the transaxle.
(b) Disconnect the ECM connector.
(c) Measure the resistance between terminals SLT+ and
SLT± of ECM connector.
OK:
Resistance: 5.0 to 5.6  at 20
C (68

DTC P0776 PRESSURE CONTROL SOLENOID ºBº
PERFORMANCE (SHIFT SOLENOID VALVE
SL2)
SYSTEM DESCRIPTION
The ECM uses signals from the vehicle speed sensor to detect the actual gear position (1st, 2nd, 3rd or O/D
gear).
Then the ECM compares the actual gear with the shift schedule in the ECM memory to detect mechanical
troubles of the shift solenoid valves and valve body.
DTC No.DTC Detecting ConditionTrouble Area
P0776The gear required by the ECM does not match the actual gear
when driving (2±trip detection logic)
Shift solenoid valve SL2 is stuck open or closed

Valve body is blocked up or stuck

Automatic transaxle (clutch, brake or gear etc.)
INSPECTION PROCEDURE
1 INSPECT SHIFT SOLENOID VALVE(SL2)
(a) Remove the shift solenoid valve SL2.
(b) Measure the resistance between terminals.
OK:
Resistance: 5.1 to 5.5
at 20C (68F)
(c) Connect the positive (+) lead with a 21 W bulb to terminal
2 and the negative (±) lead to terminal 1 of the solenoid
valve connector, then check the movement of the sole-
noid valve.
OK:
The solenoid valve makes an operating noise.
