Component Testing

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

NOTE:

If moist environmental conditions: rain, snow, vehicle wash, etc. are present please refer to the appropriate Diagnostic Aids section above before doing component tests.

Ignition OFF, disconnect the X1 harness connector at the A15 Starter Generator.
Test for 10-35Ω between the reference terminal 3 and the reference terminal 4.
- If not within the specified range
  Replace the A15 Starter Generator.
- If within the specified range
Test for 30-60Ω between the signal (S1) terminal 1 and the signal (S3) terminal 5.
- If not within the specified range
  Replace the A15 Starter Generator.
- If within the specified range
Test for 30-60Ω between the signal (S4) terminal 2 and the signal (S2) terminal 6.
- If not within the specified range
  Replace the A15 Starter Generator.
- If within the specified range
Test for greater than 10,000Ω between the terminals listed below and A15 Starter Generator case:
- Signal (S1) terminal 1
- Signal (S4) terminal 2
- Reference terminal 3
- Reference terminal 4
- Signal (S3) terminal 5
- Signal (S2) terminal 6
- If less than 10,000Ω
  Replace the A15 Starter Generator.
- If 10,000Ω or greater
Test for infinite resistance between the terminals listed below:
- Terminals 1 and 3
- Terminals 1 and 2
- Terminals 2 and 3
- If less than infinite resistance
  Replace the A15 Starter Generator.
- If infinite resistance
Refer to Circuit/System Testing.
