DTC 41
DTC 41: Abnormal Signal Reception Error1. Check the wheel is mounted with the tire pressure sensor.
Is the tire pressure sensor mounted properly?
YES - Go to step 9.
NO - Go to step 2
2. Install the tire pressure sensor properly.
Was the tire pressure sensor replaced?
YES - Go to step 3.
NO - Go to step 9.
3. Test-drive the vehicle above 15 mph (24 km/h) for 40 continuous seconds (better than 40 cumulative seconds), or memorize the ID with the HDS.
4. Test-drive the vehicle and monitor the VSP signal with the HDS.
Is the VSP signal OK?
YES - Go to step 9.
NO - Go to step 5.
5. Turn the ignition switch OFF, then disconnect the TPMS control unit connector B (22P).
6. Measure the voltage between the TPMS control unit connector B (22P) terminals No. 20 and body ground.
Does voltage pulse from 0 to about 5 V or more?
YES - Check for loose wires or poor connections at the TPMS control unit connectors. If necessary, substitute a known-good TPMS control unit and recheck.
NO - Go to step 7.
7. Disconnect the PCM connector B (56P).
8. Check for continuity between TPMS control unit connector B (22P) terminals No. 20 and the PCM connector B (56P) terminals No. 26.
Is there continuity?
YES - Go to step 9.
NO - Repair open in the wire between TPMS control unit and PCM.
9. Turn the ignition switch ON (II).
10. Check all wheels for the receiving/outputting condition of the signal using the HDS.
NOTE: If the response is not shown on the HDS, turn the appropriate tire 1/4 turn with the ignition switch turned OFF, then retry after turning the ignition switch ON (II) again.
Is there a response from at least one wheel, which appears in at least three times of retry cone turn of the tire)?
YES - The system is OK at this time. Clear the DTC.
NO - Check for loose wires or poor connections at the TPMS control unit connectors. If necessary, substitute a known-good TPMS control unit and recheck.
