T-331
Error code [EOC07H] Counterclockwise slewing SOL Lo-error
Error code EOC07H
Details of
failure
Counterclockwise slewing SOL Lo-error
Failure-determining
conditions
Solenoid resistance undershot 4 Ω (when output is ON).
Short circuit to power supply line detected (when output is OFF).
Assumed cause and
diagnostic method
Cause Diagnostic method and action to be taken
1
Harness short circuit to
power supply line
Check the related circuits for any short circuit to ground.
2
Counterclockwise slewing
SOL fault
Check if the solenoid functions normally.
[Additional information] Refer to T-333 for relevant electric circuit and location
Error code [EOC07L] Counterclockwise slewing SOL Hi-error
Error code EOC07L
Details of
failure
Counterclockwise slewing SOL Hi-error
Failure-determining
conditions
Solenoid resistance exceeded 20 kΩ (when output is OFF).
Assumed cause and
diagnostic method
Cause Diagnostic method and action to be taken
1
Open circuit in harness
related to counterclockwise
slewing SOL
Check the related circuits for any open circuit.
2
Counterclockwise slewing
SOL fault
Check if the solenoid functions normally.
