Component Testing

Static Test

1. Ignition/Vehicle - Off
2. Disconnect the electrical connector: M47 Reverse Inhibit Solenoid Actuator
NOTE:

The component's temperature should be 20 to 30°C (68 to 86°F) while testing.

3. Test for 11 to 15 ohms between the test points: Control terminal 1/A & B+ terminal 2/B
   • If not between 11 and 15 ohms 

     Replace the component: M47 Reverse Inhibit Solenoid Actuator

   • Go to next step: If between 11 and 15 ohms 
4. Test for infinite resistance between the test points: Each terminal of the component & The component's housing
   • If less than infinite resistance 

     Replace the component: M47 Reverse Inhibit Solenoid Actuator

   • Go to next step: If infinite resistance 
5. All OK.

Dynamic Test

1. Ignition/Vehicle - Off
2. Disconnect the electrical connector: M47 Reverse Inhibit Solenoid Actuator
3. Connect a 3 A fused jumper wire between the test points: B+ terminal 2/B & 12 V
CAUTION:

Complete the testing as quickly as possible in order to prevent overheating and damaging the component.

5. Momentarily connect a jumper wire between the test points: Control terminal 1/A & Ground

   Verify the component produces a clicking sound: M47 Reverse Inhibit Solenoid Actuator

   • If a click cannot be heard or felt 

     Replace the component: M47 Reverse Inhibit Solenoid Actuator

   • Go to next step: If a click can be heard or felt 
6. All OK.
