Baja F4-2.5L SOHC (2003)
CONTROL MODULE
-
Based on signals from the related switches and sensors, the cruise control module controls all the following control functions:
Constant speed control; speed setting control; deceleration control; acceleration control; resume control; manual cancel control; low speed limit
control; stepping motor control; cruise control
-
The control module (A) is located inside of the front pillar lower portion (passenger side).
FAIL-SAFE FUNCTION
The cruise control system has a fail-safe function that cancels the cruise control operation when any of the following conditions occurs.
Conflict Between Cruise Control Switches And Cancellation Signal Generating Switches
1. The cruise control system is deactivated if any of the cruise control switches (SET/COAST, RESUME/ACCEL, and CANCEL switches) is turned
ON while any of the cancellation signal generating switches (brake, stop lamp, clutch, and inhibitor switches) is being operated. The system is
re-activated when the cruise control switch is turned OFF and then turn ON again after the cancellation signal generating switch has been returned
to its released position.
2. The cruise control system becomes deactivated if the ignition switch is turned ON with any of the cruise control switches in the ON position. The
system deactivating function is retained until the ignition switch is turned OFF.
Abnormalities In Electric Circuits
The cruise control system is deactivated and the set speed is also canceled if any of the following abnormalities occurs in the system's electric circuits.
The system deactivation function is retained until the ignition switch or the main switch is turned OFF.
1. The stepping motor terminal is grounded or disconnected; or the stepping motor drive circuit is broken due to a short-circuit.
2. The stepping motor clutch drive circuit is shorted.
3. Vehicle speed variation in a 350 ms period exceeds ±10 km/h (±16 MPH).
4. Fusion has occurred in an internal relay and is detected while the vehicle is running with the cruise control deactivated.
5. The cruise control module becomes inoperative or its operation is faulty.
6. There is discrepancy between the values stored in the two RAMs of the control module.
7. An abnormality is detected as a result of the self-diagnosis performed after turning ON of the ignition switch.
Abnormalities In Stepping Motor
The cruise control system is deactivated if either of the following abnormalities occurs in the stepping motor.
1. The stepping motor does not operate properly.
2. The stepping motor is energized for unduly long period and too frequently. When the system is deactivated by any of these causes, it cannot be
reactivated for 2 - 20 minutes after detection of the abnormal condition.
