Component Testing

Shift Position Switch Test

1. Ignition OFF, disconnect the shift position switch harness at the TCM.
2. With the switch in the following positions, test for infinite resistance between the ground terminal A and the signal terminal F.
   • R
   • OD
   • D
   • 2
   • 1
   • If not the specified value, replace the shift position switch.
3. With the switch in the following positions, test for less than 2 Ω between the ground terminal A and the signal terminal F.
   • P
   • N
   • If greater than the specified range, replace the shift position switch.

Relay Test

1. Ignition OFF, disconnect the CRNK relay.
2. Test for 60 - 250 Ω between terminals 85 and 86.
   • If not within the specified range, replace the relay.
3. Test for infinite resistance between the following terminals:
   • 30 and 86
   • 30 and 87
   • 30 and 85
   • 85 and 87
   • If not the specified value, replace the relay.
4. Install a 20 A fused jumper wire between relay terminal 85 and 12 V. Install a jumper wire between relay terminal 86 and ground. Test for less than 2 Ω between terminals 30 and 87.
   • If greater than specified range, replace the relay.
