Testing The TR Switch

WARNING: This page is about a different car, the 2002 Mazda 626. However, it is still accessible from the selected car via links, so may be relevant.

Static testing procedures allow for shop testing of the TR switch on the vehicle or on the bench. Completion of these tests prove out the TR switch electronically.

CAUTION:

For resistance checks, be sure that the test select dial is set to the "TR/MLP SENSOR TEST" position or the ohmmeter may be damaged.

NOTE:

Using a digital volt-ohmmeter and the transaxle tester, perform the DTC troubleshooting as indicated on the DTCs which were displayed. See DIAGNOSTIC TESTS .
Perform repairs as indicated by the pinpoint test. Always erase all DTCs, retest resistance test-TR switch and road test the vehicle after a repair.
