Pin Voltage Tests

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

NOTE: For circuit and terminal identification, see CONNECTOR IDENTIFICATION and WIRING DIAGRAMS .

Checking pin voltages at TCM harness connectors determines whether it is receiving and transmitting proper voltage signals. Access TCM connectors. TCM is located behind glove compartment. Using DVOM, carefully backprobe TCM connectors. Measure voltage between specified terminals and terminals No. 1C or 1Y. See Fig 1-Fig 3 .
