Component Testing

WARNING: This page is about a different variant/trim than selected.

NOTE:

If the a/trans wiring harness circuits fail the circuit tests, replace the harness; do not repair.

Vehicle ON.
Verify that DTC P1AF0, P1AF2, P1B43, P1B44, P1B0B, or P1B0C is not set.
- If any of the DTCs are set
  Refer to Diagnostic Trouble Code (DTC) List - Vehicle .
- If none of the DTCs are set
Vehicle OFF, disconnect the X175/X176 harness connector at the transmission.
Install the DT-48493 jumper harness to the transmission side only.
Test for 6-9 Ω between the reference circuit terminal 15 and the reference circuit terminal 16.
- If less than 6 Ω
1. Disconnect the harness connector at the M15B Drive Motor 2.
2. Test for infinite resistance between the reference circuit terminal 15 and the reference circuit terminal 16.
  - If less than infinite resistance, replace the a/trans wiring harness.
  - If infinite resistance, replace the M15B Drive Motor 2.
- If greater than 9 Ω
1. Disconnect the harness connector at the M15B Drive Motor 2.
2. Test for less than 2 Ω in the reference circuits end to end.
  - If 2 Ω or greater, replace the a/trans wiring harness.
  - If less than 2 Ω, replace the M15B Drive Motor 2.
- If between 6-9 Ω
Test for 19-23 Ω between the signal circuit 2 terminal 20 and the signal circuit 2 terminal 21.
- If less than 19 Ω
1. Disconnect the harness connector at the M15B Drive Motor 2.
2. Test for infinite resistance between the signal circuit 2 terminal 20 and the signal circuit 2 terminal 21.
  - If less than infinite resistance, replace the a/trans wiring harness.
  - If infinite resistance, replace the M15B Drive Motor 2.
- If greater than 23 Ω
1. Disconnect the harness connector at the M15B Drive Motor 2.
2. Test for less than 2 Ω in the signal circuits end to end.
  - If 2 Ω or greater, replace the a/trans wiring harness.
  - If less than 2 Ω, replace the M15B Drive Motor 2.
- If between 19-23 Ω
Test for 22-26 Ω between the signal circuit 1 terminal 17 and the signal circuit 1 terminal 18.
- If less than 22 Ω
1. Disconnect the harness connector at the M15B Drive Motor 2.
2. Test for infinite resistance between the signal circuit 1 terminal 17 and the signal circuit 2 terminal 18.
  - If less than infinite resistance, replace the a/trans wiring harness.
  - If infinite resistance, replace the M15B Drive Motor 2.
- If greater than 26 Ω
1. Disconnect the harness connector at the M15B Drive Motor 2.
2. Test for less than 2 Ω in the signal circuits end to end.
  - If 2 Ω or greater, replace the a/trans wiring harness.
  - If less than 2 Ω, replace the M15B Drive Motor 2.
- If between 22-26 Ω
Test for greater than 10,000 Ω between the terminals listed below and ground:
- Reference circuit terminal 15
- Reference circuit terminal 16
- Signal circuit 2 terminal 20
- Signal circuit 2 terminal 21
- Signal circuit 1 terminal 17
- Signal circuit 1 terminal 18
- If less than 10,000 Ω
1. Disconnect the harness connector at the M15B Drive Motor 2.
2. Test for less than infinite resistance between the appropriate terminal and ground.
  - If less than infinite resistance, replace the a/trans wiring harness.
  - If infinite resistance, replace the M15B Drive Motor 2.
- If 10,000 Ω or greater
Test for infinite resistance between the terminals listed below:
- Terminals 15 and 17
- Terminals 15 and 20
- Terminals 17 and 20
- If less than infinite resistance
1. Disconnect the harness connector at the M15B Drive Motor 2.
2. Test for less than infinite resistance between the appropriate terminals.
  - If less than infinite resistance, replace the a/trans wiring harness.
  - If infinite resistance, replace the M15B Drive Motor 2.
- If infinite resistance
