GEAR SELECTOR SWITCH

1. Locate the gear selector switch on the transmission.

Remove the wiring harness connector and insert the

multimeter probes into the switch.

2. Move the gear selector handle to each of the 5 drive

positions (HIGH, LOW, NEUTRAL, REV, or PARK).

3. Test for continuity between the switch contacts and

connector leads. Replace the switch if no continuity

or high resistance is found in any of the gear

The resistor module relays a different resistance reading

to the ECM depending on which gear is selected by the

operator. If the module fails, the ECM will not be able to

determine what gear the transmission is in.

1. Disconnect the ECM harness connector from the

ECM. Locate pins 23 (WHITE) and 30 (VIOLET).

2. Set the multimeter to register OHMS (resistance).

Insert the RED probe into pin 23 and the BLACK

probe into pin 30.

3. Reference the Resistance Table for specifications. If

any of the tests fail, replace the resistor module.
