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 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 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 a 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 , «DIAGNOSTIC FUNCTION - HOW TO READ DIAGNOSTIC TROUBLE CODES»(/mitsubishi/lancer-evolution/x-2007-2016/remont/cruise-control-systems/#cruise-control-lancer-evolution) ).
  4. If you cannot verify the condition and there are no cruise control system DTCs, the malfunction may be intermittent (Refer to «HOW TO COPE WITH INTERMITTENT MALFUNCTIONS»(/mitsubishi/lancer-evolution/x-2007-2016/remont/hoistjack/#general-information-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-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 , «DIAGNOSTIC FUNCTION - HOW TO ERASE DIAGNOSTIC TROUBLE CODES»(/mitsubishi/lancer-evolution/x-2007-2016/remont/cruise-control-systems/#cruise-control-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 , «DIAGNOSTIC FUNCTION - HOW TO READ DIAGNOSTIC TROUBLE CODES»(/mitsubishi/lancer-evolution/x-2007-2016/remont/cruise-control-systems/#cruise-control-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-lancer-evolution__diagnostic-trouble-code-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.

TROUBLESHOOTING HINTS (THE MOST LIKELY CAUSES FOR THIS CASE:)

  1. Damaged harness or connector.
  2. Malfunction of the cruise control switch.
  3. Malfunction of the clock spring.
