19 Measure the resistance between terminals of internal wiring harness.
Is the resistance within the values shown?		 Refer to Component Resistance Chart. No problem found, exit table Go to Step 21
20 Inspect for resistance:
  • Inspect the transaxle wiring for poor electrical connections at the transaxle.
  • Look for possible bent, backed out, deformed of damaged terminals.

Check for weak terminal tension.		 - Verify repair and Go to Step 12 No problem found, exit table
21 Replace the internal wiring harness.
Is the replacement complete?		 - No problem found, exit table -
22 Replace the component.
Is the replacement complete?		 - No problem found, exit table -
