2005 Mitsubishi Lancer L4-2.4L SOHCSECTION Inspection Procedure 7
When "CRUISE" (MAIN) Switch is Turned "ON", "CRUISE" Indicator Light Inside Combination Meter does not Illuminate. (However, Auto-cruise Control is Normal).
CIRCUIT OPERATION
The ECM or PCM detects "CRUISE" (MAIN) switch "ON" signal to illuminate the "CRUISE" indicator light on the combination meter.
COMMENT
Connector(s), wiring harness between the ECM or PCM and the combination meter, the indicator light bulb and the ECM or PCM may be defective.
TROUBLESHOOTING HINTS
- Malfunction of the indicator light bulb.
- Damaged harness or connector.
- Malfunction of the ECM.
- Malfunction of the PCM .
DIAGNOSIS
Required Special Tool:

2. Turn the ignition switch to the "ON" position.
3. Measure the terminal voltage between ECM connector C-133 terminal 13 or PCM connector C-134 terminal 13 and ground.
- When the ignition switch to the "ON" position, the voltage should measure battery positive voltage (approximately 12 volts).
- When the ignition switch to the "LOCK" (OFF) position, the voltage should measure 0.5 volt or less.
4. Turn the ignition switch to the "LOCK" (OFF) position.
5. Connect ECM connector C-133 or PCM connector C-134 .
Q: Is the measured voltage battery positive voltage (approximately 12 volts) when ignition switch to the "ON" position and 0.5 volt or less when ignition switch to the "OFF" (LOCK) position?
YES: Go to Step 10.
NO: Replace the combination meter (Refer to Combination meter assembly). Then go to Step 11.
STEP 10. Check the symptoms.
Q: Does the auto-cruise control indicator light illuminate when "CRUISE" (MAIN) switch is turned "ON"?
YES: It can be assumed that this malfunction is intermittent. (Refer to How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunction).
NO: Replace the ECM or PCM [Refer to Engine Control Module (ECM) and Powertrain Control Module (PCM)]. Then go to Step 11.
STEP 11. Check the symptoms.
Q: Does the auto-cruise control indicator light illuminate when "CRUISE" (MAIN) switch is turned "ON"?
YES: Return to Step 1.
NO: The procedure is complete.
