Problem Repair (No DTC)
If PEPS system has problems, but no DTC is stored in PEPS system, this problem is called a problem without
DTC.
Troubleshooting recommendation: check corresponding components according to problem symptom, and
troubleshoot following the vehicle repair manual.
Diagnostic Help
1. Connect X-431 3G diagnostic tester (the latest software) to Data Link Connector (DLC), and make it
communicate with vehicle electronic module by the data network.
2. Confirm that malfunction is current, and carry out diagnostic test and repair procedures.
3. If DTC cannot be deleted, the malfunction is current.
4. Visually check the related wire harness and connector.
5. Check and clean all wire harness connectors and grounds related to current DTC.
6. If multiple trouble codes were set, refer to the circuit diagrams to look for any common ground circuit or
power supply circuit applied to the DTC.
7. Refer to any Technical Bulletin that may apply to the malfunction.
Intermittent DTC Troubleshooting
If malfunction is intermittent, perform the followings:
Check if connectors are loose.
Check if wire harnesses are worn, pierced, pinched or partially broken.
Wiggle related wire harnesses and connectors and observe if signal is interrupted in the related circuit.
If possible, try to duplicate the conditions under which the DTC was set.
Look for the data that has changed or the DTC to be reset during the wiggle test.
Look for broken, bent, protruded or corroded terminals.
Check and clean all wire harness connectors and grounding parts related to the current DTC.
Remove the PEPS controller from the malfunctioning vehicle and install it to a new vehicle and perform a
test. If DTC cannot be cleared, the PEPS controller is malfunctioning. If DTC can be cleared, reinstall the
PEPS controller to original vehicle.
If multiple trouble codes were set, refer to the circuit diagrams to look for any common ground circuit or
power supply circuit applied to the DTC.
Refer to Technical Bulletin that is applied to the malfunction.

Ground Inspection
Groundings are very important to entire circuit system, which are normal or not can seriously affect the entire
circuit system. Ground points are often exposed to moisture, dirt and other corrosive environments. Corrosion
(rust) and oxidation may increase load resistance. This situation will seriously affect the normal operation of
the circuit. The operations to check the ground points are as follows:
1. Remove the ground bolt or nut.
2. Check all contact surfaces for tarnish, dirt and rust, etc.
3. Clean as necessary to ensure that contacting is in a good condition.
4. Reinstall the ground bolt or nut securely.
5. Check if add-on accessories interfere with the ground circuit.
6. If several wire harnesses are crimped into one ground terminal, check if they are installed correctly. Make
sure all wire harnesses are clean, securely fastened and providing a good ground path.
