DTC 41: Abnormal Signal Reception Error
- Inspect for an aftermarket electrical device(s) (such as an inverter, battery charger, etc) interfering with the RF signal from the sensors when turning the ignition switch to ON (II).
- If DTC 32, 34, 36 or 38 is also set, troubleshoot those DTCs first.
- Turn the ignition switch to LOCK (0).
- Check all four wheels to make sure they are the TPMS type with the tire pressure sensor.
Is each wheel a TPMS type with a tire pressure sensor mounted on the vehicle?
YES - Go to step 3.
NO - Install a TPMS type wheel, and memorize the sensor ID. Drive the vehicle above 15 mph (24 km/h) continuously for 40 seconds, or memorize the ID with the HDS (see HOW TO CLEAR DTCS ).
- Test-drive the vehicle.
- Check the VEHICLE SPEED in the TPMS DATA LIST with the HDS.
Is the vehicle speed indicated?
YES - Go to step 8.
NO - Go to step 5.
- Turn the ignition switch to LOCK (0).
- Turn the ignition switch to ON (II).
- Check for DTCs with the HDS.
Is DTC 85 indicated?
YES - Go to the DTC 85 troubleshooting (see DTC 85: F-CAN COMMUNICATION FAILURE ). ■
NO - Check for loose terminals and poor connections at the TPMS control unit. If necessary, substitute a known-good TPMS control unit (see TPMS CONTROL UNIT REPLACEMENT ), and recheck. ■
- Turn the ignition switch to LOCK (0).
- Turn the ignition switch to ON (II).
- Check TPMS DATA LIST for LF, RF, LR, and RR TIRE PRESSURE SENSOR STATUS changing to NORMAL with the HDS.NOTE: If UNDEFINED is shown on the sensor transmitter status, turn the ignition switch to LOCK (0), rotate the tire 1/4 turn, then turn the ignition switch to ON (II), and try again. If UNDEFINED is still displayed, repeat this procedure until NORMAL is shown.
Is NORMAL indicated within one full turn of the tire?
YES - The system is OK at this time. Clear the DTC with the HDS. ■
NO - Check for loose terminals and poor connections at the TPMS control unit. If necessary, substitute a known-good TPMS control unit (see TPMS CONTROL UNIT REPLACEMENT ), and recheck. ■
