Mitsubishi Trouble Code Info

SRS-ECU DIAGNOSIS CODE SET

96 & later are OBD2 systems and require a scanner.

Accessing Diagnostic Trouble Codes

  • Turn ignition switch to OFF position
  • Locate Data Link Connector (DLC), next to fuse box.
  • Connect voltmeter positive lead to DLC terminal #1 and Negative lead to terminal #12 (ground).
  • Turn Ignition switch to ON position.
  • codes are read out by 12 volt pulses of voltmeter.
  • A constant repetition of short pulses is normal.
  • Signals will appear on voltmeter a long and short 12 volt pulses.
  • long pulses represent tens
  • short pulses represent ones (4 long pulses and 3 short pulses indicates code 43)

  1. Ground Data Link Connector terminal # 1.
  2. Set the ignition switch to "ON", the Malfunction Indicator (check engine) Lamp will illuminate for a particular duration and a certain number of times.
  3. Clear the trouble codes by disconnecting the vehicle battery negative terminal for 16 seconds or longer

EXAMPLES

No Codes--normal

  • The Lamp will illuminate for 0.5 seconds, then stay Off for 0.5 seconds, this pattern will repeat until the ignition is turned OFF.

Code 13

  • The Lamp will illuminate one time for approximately 0.5 second. This will represent one unit of ten. There will be approximately a one second delay and then the Lamp will illuminate three times for approximately 0.2 seconds with 0.2 second delay between deflections. This will represent three units of one.

Code 23

  • The Lamp will illuminate two times for approximately 0.5 second with approximately 0.3 second delay between deflections. This will represent two units of ten. There will be approximately a one second delay and then the Lamp will illuminate three times for approximately 0.2 seconds with 0.2 second delay between deflections. This will represent three units of one..

Clearing Trouble Codes

Diagnostic trouble codes may be cleared by disconnecting the battery ground cable for at least 20 seconds. Reconnect negative battery cable and recheck codes to confirm the repair.

  1. Count the number of times the malfunction indicator lamp (check engine lamp) on the instrument panel flashes on and off. The number of flashes represents the trouble code. There is a slight pause between the flashes representing the first and second digits of the code. Longer pauses (approx. 4 seconds) separate individual trouble codes.
  2. Repair the malfunction while referring to the inspection chart for diagnostic trouble codes.
  3. After disconnecting the battery cable from the battery (-) terminal for 10 seconds or more, reconnect the cable.
  4. Start the engine and run it at idle for about 15 minutes after the engine has warmed up.
