Overtightening the harness connector retaining fastener will damage the primary TEC
controller.
After you plug connector P01 back into the TEC, torque the retaining fastener for P01

Fail One or more of the resistance measurements were not good. Repair or replace worn or
damaged parts as required. Go to
