Checking Cables and Sensors

Checking Cables And Sensors







- Ignition off.

Check control module and engine speed sensor connectors for contact resistance and oxidation according to Checking wiring and terminals. Permanent faults.

Check power supply cable between control module #A59 and transmission connector #16 for an open-circuit according to Checking wiring and terminals. Permanent faults and for a short-circuit to ground according to Checking wiring and terminals. Permanent faults.

Check signal cable between control module #A41 and transmission connector #17 for an open-circuit according to Checking wiring and terminals. Permanent faults and for a short-circuit to ground according to Checking wiring and terminals. Permanent faults.

HINT: With control module connected, ignition on and a voltmeter connected between transmission connectors #16 and #17 (control module side), the voltage should be 8-12 V.

Remedy as necessary.
