General information
- Malfunction indicator lamp (MIL) will illuminate continuously if permanent faults are recorded.
- Malfunction indicator lamp (MIL) will illuminate briefly and then switch off if intermittent faults are recorded.
- ECM operates in backup mode if sensors fail , to enable vehicle to be driven to repair shop.
- Trouble codes can be displayed by the MIL or by using an analogue voltmeter or Scan Tool connected to the data link connector (DLC).
Accessing
Using malfunction indicator lamp (MIL)
- Ensure ignition switched OFF.
- Access data link connector (DLC) 1
- Jump data link connector (DLC) terminals STI and GNO 2
- Switch ignition ON .
- Count MIL flashes. Note trouble codes. Compare with trouble code table .
o 1.2 second flashes indicate the ‘tens’ of the trouble code 3 [A).o 0.4 second flashes indicate the ‘units’ of the trouble code 3 [C).o A 1.6 second pause (MIL OFF) separates ‘tens’ and ‘units’ 3 [B).o A 0.4 second pause (MIL OFF) separates each flash 3 [D).o A 4 second pause separates each trouble code 3 [E) .o For example: Trouble code 12 displayed D. Throttle position (TP) sensor.
- Switch ignition OFF.
- Trouble codes can also be displayed by using a Scan Tool connected to the data link connector (DLC) 1
Using analogue voltmeter
- Ensure ignition switched OFF.
- Access data link connector (DLC) 1
- Connect an analogue voltmeter between data link connector (DLC) terminal STO and ground 1
- Set analogue voltmeter to a DC voltage range of 0-20 V.
- Jump data link connector (DLC) terminals STI and GND 4
- Switch ignition ON.
- Count voltmeter needle deflections. Note trouble codes. Compare with trouble code table.
o 1.2 second needle deflections indicate the ‘tens’ of the trouble code 3 [A).o 0.4 second needle deflections indicate the ‘units’ of the trouble code 3 [C).o A 1.6 second pause separates ‘tens’ and ‘units’ 3 [B) .o A 0.4 second pause separates each needle deflection 3 [D).o A 4 second pause separates each trouble code 3 [E) .o For example: Trouble code 12 displayed 3. Throttle position (TP) sensor.
- Switch ignition OFF.
- Trouble codes can also be displayed by using a Scan Tool connected to the data link connector (DLC) 1
Erasing
- Ensure ignition switched OFF.
- Disconnect battery ground cable.
- Depress brake pedal for 5-10 seconds.
- Reconnect battery ground cable.
- Repeat accessing procedure to ensure no trouble codes remain in ECM fault memory.
NOTE: Disconnecting battery ground lead may also erase memory from electronic units, such as radio.
