ECU Fault Codes
ECU Fault Codes
Quick reference to the Link ECU fault and error codes
Also available on screen in PCLink Help, the following list shows possible ECU fault codes, causes of ECU faults and errors, and recommended solutions.
If a fault is displayed that is not listed, contact your dealer for further advice. You can use Find (Ctrl F) in PCLink to find the fault code. ECU fault codes are displayed in PCLink in the ECU Status runtime values. They may also be displayed on a Check Engine Light or a digital dashboard display. Fault codes can be cleared by selecting Clear Fault Codes in the ECU Controls drop down menu. This list will be updated as new fault conditions are added. Also check all PCLink runtime values for real time information on ECU parameters.

| 69 | Electronic Throttle 1 Control Max Duty Cycle Reached | E-Throttle duty cycle has been within +/-5% of its maximum value continuously for more than 2 seconds. | In this situation the E-Throttle system is shut down and cannot be restarted until the ECU power has been cycled. There may be something restricting throttle plate movement or the wiring to the throttle motor has been disconnected meaning the ECU has tried to move the throttle plate but has needed to apply to much power for too long. |
| 70 | Electronic Throttle 1 Control Min Duty Cycle Reached | The E-Throttle duty cycle has been within +/-5% of its minimum value continuously for more than 2 seconds. | In this situation the E-Throttle system is shut down and cannot be restarted until the ECU power has been cycled.

The Electronic Throttle Control will immediately be shut down and will not be allowed to re-activate until the ECU power is cycled.

| 72 | Electronic Throttle Control Sensor Supply Voltage Error | If the 5V supply is less than 4.85V for a continuous period of at least 2 seconds this fault code will be generated.

| 75 | Electronic Throttle 1 Position Control Error | Throttle Plate Position unable to track Target Position. In this fault state the throttle plate cannot maintain or achieve the desired target position.

Expected relative position between TPS (Main) and TPS (Sub) has exceeded the specified tolerance for a continuous period of more than 2 seconds. In this fault state the ECU must assume the throttle plate feedback to be invalid and that a problem exists with either with the TPS(Main) or TPS(Sub) signal. The ECU cannot detect which signal is invalid which means the plate position is effectively unknown and cannot be controlled. | Sensor Fault, test sensor. Sensor Calibration Fault, recalibrate sensors. |
| 77 | AP (Main) and AP (Sub) tracking Error | Accelerator Position Signal Tracking Error. Expected relative position between the APS (Main) and APS (Sub) has exceeded the specified tolerance of +/- 3.0% for a continuous period of more than 2 seconds. In this fault state the ECU must assume the accelerator position feedback to be invalid and that a problem exists with either with the APS(Main) or APS(Sub) signal. The ECU cannot detect which signal is invalid which means the accelerator position is effectively unknown. At this point the ECU will force a fault condition value to 5.0%. It should be noted that in this fault condition the ECU still has control over the throttle plate and this will continue to be controlled as normal which also means the Electronic Throttle Control isolating relay will remain ON. | Sensor Fault, test sensor.
