Help
- Severe trouble is not defined.
- Perform the immobilizer coding again.
- Check the ECU wiring harness.
• Check the ECU pin #34 for open and short.
- Check the immobilizer unit for open and short or check the supply voltage.
- Check the immobilizer antenna and transponder for damage.
- Replace the ECU if required.
- HFM sensing values are higher than specified sensing values (not circuit failure but sensor failure).
- HFM sensing values are lower than specified sensing values (not circuit failure but sensor failure).
- If the vehicle speed is below 15 km/h (even over 1,600 rpm of engine speed) when the “Vehicle speed sensor” cod­ing is “YES” (Non-ABS vehicle), the vehicle speed input failure appears.
- If the “Vehicle speed sensor” coding is “NO” (CAN, ABS/ESP vehicle), the trouble code does not appear.
- Check the “Vehicle speed sensor” coding.
- If the pulse from speed pulse ring is more than specified value during the specified interval when the “Vehicle speed sensor” coding is “YES” (Non­ABS vehicle), the vehicle speed sen­sor failure appears.
- Specified pulse: 52 pulses/1 revolution
- Check the “Vehicle speed sensor” coding.
- CAN related device in ECU is defective.
- CAN communication between units is failure.
- Even though the ESP or TCCU is not installed in the vehicle, the vehicle speed signal is sent through CAN communication.
- ABS/ESP variant coding is failure.
- CAN communication is failure.
- TCU variant coding is failure.
- CAN communication between units is failure.
- CAN cluster is failure.
- CAN communication between units is failure.

Help
- Auto cruise acceleration switch or related wiring harness is defective.
- Auto cruise OFF switch or related wiring harness is defective.
- Auto cruise switch or related wiring harness is defective.
- Auto cruise deceleration switch or related wiring harness is defective.
- Auto cruise safety switch or related wiring harness is defective.
- ECU internal failure
- ECU internal failure
- Engine mount level control circuit is failure.
- Engine mount level control circuit is short to B+.
- Engine mount level control circuit is short to ground.
- The “Neutral” signal from manual transmission is sent to CAN cluster. Then, CAN cluster sends this signal to ECU via CAN communication line.
- ECU cannot determine where the sig­nal problem is; in neutral switch, wir­ing or CAN communication line.
- Check the neutral switch wiring harness.
