Diagnosis code is generated under either of the following conditions.
(1) Phase difference between cylinder recognition sensor and engine speed sen-
sor deviates from the standard value when engine speed is 20 rpm or more.
(2) No signal from the cylinder recognition sensor during the 132-pulse inputs of
the engine speed sensor signal after recognition of the gap of the engine
speed sensor.
(3) Abnormal signal (timing) of cylinder recognition sensor signal during the 240-
pulse inputs of the engine speed sensor signal.
• In the case of above problem (1)
• System recovers when phase difference between cylinder recognition sen-
sor and engine speed sensor is within the standard value when engine
speed is 20 rpm or more.
• In the case of above problem (2)
• System recovers when signals from cylinder recognition sensor are input.
• In the case of above problem (3)
• System recovers when the signal (timing) of cylinder recognition sensor
signal during the 240-pulse inputs of the engine speed sensor signal be-
comes normal.
• In the case of above problem (1)
• Control is effected using engine speed sensor.
• In the case of above problems (2) and (3)
• Control is effected using engine speed sensor.
• Auto cruise control is stopped.

Vehicle speed remains 2 km/h or less for 20 seconds when engine speed is 1000
rpm or more, clutch pedal is released and transmission neutral signal indicates
that transmission is in gear.
System recovers when vehicle speed remains 2 km/h or more for 3 seconds
when engine speed is 1000 rpm or more, clutch pedal is released and transmis-
sion neutral signal indicates that transmission is in gear.
• Auto cruise control is stopped.
• Vehicle speed limiting control is stopped. (Engine speed is also limited.)

Idling speed adjustment potentiometer voltage remains less than 0.7 V for 3 sec-
onds.
System recovers when idling speed adjustment potentiometer voltage remains
0.7 V or more for 1 second.
• Control is effected with auto idle permanently selected.
• Actuator test "BA: VGT Test" is stopped.
