DTC 53
DTC 51, 53, 55, 57: Tire Pressure Sensor Registration Error1. Turn the ignition switch OFF.
2. Check the indicated location to make sure the wheel is a TPMS type with the tire pressure sensor.
Is a TPMS type wheel with a tire pressure sensor mounted on the vehicle?
YES - Go to Step 8.
NO - Go to Step 3.
3. Install a known-good TPMS wheel.
4. To memorize the sensor ID, drive the vehicle above 15 mph (24 km/h) for 40 continuous seconds, or memorize the ID with the HDS.
5. Turn the ignition switch OFF.
6. Turn the ignition switch ON (II).
7. With the HDS, check the indicated tire for the tire sensor transmitter status changing to "Normal".
NOTE: If UNDEFINED is shown on sensor transmitter status, turn the ignition switch OFF, rotate the tire 1/4 turn, then turn the ignition switch ON (II), and try again. If UNDEFINED is still displayed, repeat the procedure in the previous sentence until a response is shown.
Is there at least one response in one full turn of the tire?
YES - The system is OK at this time. Clear the DTC with the HDS.
NO - Go to step 13.
8. Install a wheel with a known-good tire pressure sensor on the vehicle.
9. To memorize the sensor ID, drive the vehicle above 15 mph (24 km/h) for 40 continuous seconds, or memorize the ID with the HDS.
10. Turn the ignition switch OFF.
11. Turn the ignition switch ON (II).
12. With the HDS, check the indicated tire for the tire sensor transmitter status changing to "Normal".
NOTE: If UNDEFINED is shown on sensor transmitter status, turn the ignition switch OFF, rotate the tire 1/4 turn, then turn the ignition switch ON (II), and try again. If UNDEFINED is still displayed, repeat the procedure in the previous sentence until a response is shown.
Is there a response this time?
YES - Replace the tire pressure sensor on the customer's wheel.
NO - Go to step 13.
13. Turn the ignition switch OFF.
14. Disconnect TPMS control unit connectors A (14P) and B (20P) and the appropriate initiator 3P connector.
15. Check for continuity between the appropriate terminal in TPMS control unit connector A (14P) and the corresponding terminal in the initiator 3P connector (see table).
Is there continuity?
YES - Go to step 16.
NO - Repair the open in the appropriate wire between the TPMS control unit and the initiator.
16. Check for continuity between the appropriate terminal in TPMS control unit connector B (20P) and the corresponding terminal in the initiator 3P connector (see table).
Is there continuity?
YES - Go to step 17.
NO - Repair the open in the appropriate wire between the TPMS control unit and the initiator.
17. Check for continuity between the appropriate terminal in TPMS control unit connector B (20P) and the corresponding terminal in the initiator 3P connector (see table).
Is there continuity?
YES - Go to step 18.
NO - Repair the open in the appropriate wire between the TPMS control unit and the initiator.
18. Check for continuity between the appropriate terminal in TPMS control unit connector B (20P) and body ground (see table).
Is there continuity?
YES - Repair the short to body ground in the appropriate wire between the TPMS control unit and the initiator.
NO - Go to step 19.
19. Turn the ignition switch ON (II).
20. Measure voltage between the appropriate terminal in TPMS control unit connector B (20P) and body ground (see table).
Is there battery voltage?
YES - Repair the short to power in the appropriate wire between the TPMS control unit and the initiator.
NO - Check for loose terminals and poor connections at the TPMS control unit. If necessary, substitute a known-good TPMS control unit and recheck.
