GENERAL INFORMATION

By using the cruise control system, the driver can drive at preferred speeds in a range of approximately 40 to 200 km/h (25 to 125 mph) without depressing the accelerator pedal. For this cruise control system, in conjunction with the electronic throttle valve control system, the engine control module (ECM) electronically controls the throttle valve.

INTRODUCTION TO CRUISE CONTROL SYSTEM DIAGNOSIS

The cruise control system allows driving without stepping on the accelerator pedal by setting a random speed between approximately 40 km/h (25 mph) and 200 km/h (125 mph). Malfunctions in this system can be investigated by the following methods.

Cruise control system diagnostic trouble codes

The cruise control system consists of the engine control module (ECM), control switches and sensors. The control switches and sensors monitor the state of the vehicle. The ECM controls the throttle valve opening angle in the throttle body in accordance with the input signals from the control switches and sensors. If the ECM detects a malfunction on any of those components, the ECM estimates where the problem may be occurring, and will set a diagnostic trouble code (DTC). DTCs cover the cruise control switch, stoplight switch and ECM.

DIAGNOSTIC TROUBLESHOOTING STRATEGY

Use these steps to plan your diagnostic strategy. If you follow them carefully, you will check most of the possible causes of an cruise control system malfunction.

  1. Gather information from the customer.
  2. Verify that the condition described by the customer exists.
  3. Check the vehicle for any cruise control system DTC (Refer to «HOW TO READ DIAGNOSTIC TROUBLE CODES»(/mitsubishi/lancer-evolution/x-2007-2016/remont/cruise-control-systems/#cruise-control-except-lancer-evolution) .)
  4. If you can verify the condition but no cruise control system DTCs are set, the malfunction may be intermittent (Refer to «HOW TO COPE WITH INTERMITTENT MALFUNCTIONS»(/mitsubishi/lancer-evolution/x-2007-2016/remont/hoistjack/#general-information-except-lancer-evolution__how-to-cope-with-intermittent-malfunctions) .)
  5. If you can verify the condition but there are no cruise control system DTCs, find the fault (Refer to «SYMPTOM CHART»(/mitsubishi/lancer-evolution/x-2007-2016/remont/cruise-control-systems/#cruise-control-except-lancer-evolution__symptom-chart) .)
  6. If there is an cruise control system DTC, record the number of the code, then erase the code (Refer to «HOW TO ERASE DIAGNOSTIC TROUBLE CODES»(/mitsubishi/lancer-evolution/x-2007-2016/remont/cruise-control-systems/#cruise-control-except-lancer-evolution__how-to-erase-diagnostic-trouble-codes) .)
  7. Re-create the cruise control system DTC set conditions to see if the same cruise control system DTC will set again (Refer to «HOW TO READ DIAGNOSTIC TROUBLE CODES»(/mitsubishi/lancer-evolution/x-2007-2016/remont/cruise-control-systems/#cruise-control-except-lancer-evolution) .) If the same cruise control system DTC sets again, perform the diagnostic procedures for the set code (Refer to «DIAGNOSTIC TROUBLE CODE CHART»(/mitsubishi/lancer-evolution/x-2007-2016/remont/cruise-control-systems/#cruise-control-except-lancer-evolution__diagnostic-trouble-code-dtc-chart) .)

  3. When the "CANCEL" switch is pressed: 1.0 - 1.8 volts
  4. When the "COAST/SET" switch is pressed: 2.3 - 3.0 volts
  5. When the "ACC/RES" switch is pressed: 3.5 - 4.2 volts

Check Condition

  1. The "CRUISE" indicator light illuminates.

Judgment Criteria

  1. This DTC is set when the ECM terminal voltage is different from the standard value.
  2. Or, this DTC is set when the "COAST/SET" switch or "ACC/RES" switch is stuck to ON.

  1. For the stoplight switch, two switches, a stoplight switch for the stoplight illumination and a brake switch exclusively for the cruise control system, are incorporated to improve the reliability.
  2. As for the stoplight switch, when the brake pedal is depressed/released, the stoplight switch ON/OFF signal is transmitted from the ETACS-ECU to the ECM via CAN bus line.
  3. As for the brake switch, the ECM connector B-109 terminal number 108 monitor the state of the brake switch. The brake switch turn ON/OFF when the brake pedal is depressed/released, and the input signal to the ECM connector B-109 terminal number 108 changes. According to this change, the ECM judges the state of the brake switch.
  1. The "CRUISE" indicator light illuminates.
  1. Open/short in stoplight switch circuit.
  2. Open circuit in the brake switch circuit (between ECM connector B-109 terminal number 108 and body ground).

  4. Press the "COAST/SET" switch.
  5. Check to be sure that when the "COAST/SET" switch is released the speed is the constant speed. NOTE: If the vehicle speed decreases to approximately 15 km/h (9 mph) below the set speed because of climbing a hill for example, it is normal for the cruise control to be cancelled. When the vehicle speed becomes low-speed limit [approximately 40 km/h (25 mph)] or less, driving at constant speed will be cancelled even if the vehicle speed does not decrease 15 km/h (9 mph) or more.
