INSPECTION
Caution
Do not probe into connector terminals.
Disconnect internal harness.
For SS1, connect positive lead from ohmmeter to
SS1 tester jack and negative lead to appropriate
signal wire at SS1 connector. At SSI, signal wire is
gray and PWR wire is white.
For SS2, connect positive lead from ohmmeter to
SS2 tester jack and negative lead to appropriate
signal wire at SS2 wire connector. At SS2, signal
wire is brown and PWR wire is white.
For SS3, connect positive lead from ohmmeter to
SS3 tester jack and negative lead to appropriate
signal wire at SS3 wire connector. At SS3, signal
wire is yellow and PWR wire is white.
All resistance readings should be less than 0.5 ohms.
Is resistance less than 0.5 ohms?
Check for continuity between BAT- (engine ground)
and appropriate wire with an ohmmeter.
For SSl test, signal wire is gray and PWR
wire is white.
For SS2 test, signal wire is brown and PWR
wire is white.
For SS3 test, signal wire is yellow and PWR
wire is white.
Connection should show infinite resistance (no
continuity) - Is there continuity?
Check solenoid resistance by connecting ohmmeter at
solenoid terminals. Measure and record resistance for
all three solenoids.
Resistance for all three solenoids should be between
22 to 48 ohms.
Are shift solenoid resistance within specification?
Check for continuity between engine ground and
appropriate shift solenoid terminal (+I-)
with ohmmeter.
Connection should show infinite resistance (no
continuity)
