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.

The signal is not as expected.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Some analog channel functions do checks on the input signal to make sure it is changing as expected.

Check sensor operation and calibration.

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. 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.

 

71

 

 

 

 

 

Electronic Throttle Motor Driver (Aux 9/10) Supply Error.

 

 

 

 

If the voltage level drops below 7.0V for a continuous period of at least 2 seconds this fault code will be generated. The Electronic Throttle Control will immediately be shut down and will not be allowed to re-activate until the ECU power is cycled. Note this is different to fault code 67 and indicates that Electronic Throttle Control was shut down.

 

Measure the supply voltage. Check for blown fuses.

 

 

 

 

 

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

 

73

 

 

 

 

 

 

 

Aux 9/10 Supply

 

 

 

 

 

 

 

The voltage at the Aux 9/10 power supply pin voltage was not as expected.

 

 

 

 

 

 

 

This error applies to Xtreme, Fury and Force GDI ECUs only.

The Aux 9/10 power supply may have an electrical fault.

Check Aux 9/10 Supply runtime value (found under ECU Status runtime values). It should read similar to the Batt Voltage runtime value (found under Analog Inputs runtime values).

Check fuses.

Check outputs wired to Aux 9 and Aux 10 are not shorted to ground.

 

 

74

 

 

 

 

Analog 5V Supply Error

 

 

 

 

The ECUs 5V Out voltage is not as expected.

 

 

 

 

There may be a wiring fault on the 5V Out pin causing too much current draw.

Check Analog Output Supply runtime value (found under ECU Status runtime values). It should read between about 4.9 and 5.1 volts.

 

 

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. The Throttle Plate position and Target Position in steady state condition must remain at ALL times within +/- 2% of each other. When the Target position is changing the excepted tolerance is adjusted based on its rate of change. If this tolerance is exceeded for a continuous period of at least 2 seconds this fault code will be generated.

 

 

Redo TPS calibration procedure.

Check Electronic Throttle Control tuning.

Check mechanical operation of throttle actuator.

 

 

 

 

 

76

 

 

 

 

 

 

 

TP (Main) and TP (Sub) tracking Error

 

 

 

 

 

 

Throttle Plate Position Signal Tracking Error. 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.

Sensor Calibration Fault, recalibrate sensors.

Check that your AP(sub) 100% setting is correct.

82

 

 

 

TP (Main) not selected.

 

 

 

TPS(Main) has not been selected or has been de-selected on an analog channel when Electronic Throttle Control is being used.

 

 

Select an An Volt channel as TP (Main).

 

 

 

83 TP (Sub) not selected. TPS(Sub) has not been selected or has been de-selected on an analog channel when Electronic Throttle Control is being used.

 

 

Select an An Volt channel as TP (Sub).
84

 

 

 

Aux 9/10 Driver Fault

 

 

 

Over-Current/Over-Temperature warning from the electronic Throttle Control hardware contained inside the ECU.

 

 

This is most likely caused by excessive current draw on the Aux 9/10 channels.

 

 

85

Select an An Volt channel as AP (Main).

 

 

90

 

 

AP (Sub) not selected.

 

 

AP(Sub) has not been selected or has been de-selected on an Analog channel. The Electronic Throttle Control has been shut down

 

 

Select an An Volt channel as AP (Sub).

 

 

92

 

 

APS CAN Signal Lost

 

 

APS Error Checking is set to CAN and valid APS (Main) and APS (Sub) signals have not been received over CAN for too long.

 

 

Most likely problem is CAN bus wiring fault or an error in the external device transmitting the CAN data.
