Suspension System

General Description

TPM Receiver uses CAN communication line for diagnosis tool, receiving vehicle speed signal, sending signal to instrument cluster.
TPM Receiver receives tire information form WE sensor and it evaluates and analyzes the data. If it is necessary to inform driver about state of TPMS, the ECU sends messages to the instrument cluster via CAN.

DTC Description

The TPMS ECU checks the CAN communication lines for normal control, and sets this code if CAN controller failed to send or receive message.

DTC Detecting Condition






Diagnostic Circuit Diagram






Terminal and Connector Inspection

1. Many malfunctions in the electrical system are caused by poor harness and terminal condition.
Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage.
2. Thoroughly check all connectors (and connections) for looseness, bending, corrosion, contamination, deterioration, and/or damage.
3. Has a problem been found?






CAN Signal Circuit Inspection

Short Check (to ground)
1. Ignition "OFF" & Engine "OFF".
2. Disconnect TPMS ECU, PCM and ABS ECU connector.
3. Measure resistance between CAN LOW terminal, CAN HIGH terminal of the TPMS ECU harness connector and chassis ground.

Specification :Infinity Ohms

4. Is the measured resistance within specifications?






CAN BUS Resistance Check
1. Ignition "OFF" & Engine "OFF".
2. Disconnect TPMS ECU, PCM and ABS ECU connector.
3. Measure resistance between CAN LOW terminal and CAN HIGH terminal of the TPMS ECU harness connector.

Specification :Approx. 120Ohms

4. Is the measured resistance within specifications?






Component Inspection

1. Set up 'GDS' with 'GDS TPMS'.
2. Select the "TPMS" system.
3. Execute "DTC Analysis" mode and clear DTC.
4. Check the present DTC.
5. Is 'C1616' present ?






Verification of Vehicle Repair

After a repair, it is essential to verify that the fault has been corrected.
1. Connect GDS and select "Diagnostic Trouble Codes(DTCs)" mode.
2. Using GDS, Clear DTC.
3. Operate the vehicle within DTC Enable conditions in General information.
4. Are any DTCs present ?
