Section 6 – SR-2 Service Procedure A01B
Important Notes
•
Supply power from know good battery, a suitable power supply or by connecting a battery charger to the
unit battery. Low voltage caused by low unit battery will affect results. The threshold for battery power
influencing test results appears to be about 11.5 VDC.
•
When testing an HMI Control Panel, supply power from the interface board, not the tester. Supplying
power from the tester may result in a communication failure.
•
Be certain to make secure connections both when attaching the tester and when reconnecting the unit
wiring harnesses.
•
Never accept an initial failure. Always retest to confirm. If component fails the test, be sure wiring is
connected correctly.
•
There is a Display Self Test included in the Maintenance Menu. See Section 4 and Service Procedure
A01C for details.
Important PC Notes
The following notes apply to the pc computer used in conjunction with the Thermo King SR-2 Diagnostic Tool.
•
The SR-2 Diagnostic Tool may not function properly on pc computers running Windows ME.
•
The pc computer must be set for English. Select Control Panel – Regional and Language Options. Then

Language Options – Customize – Decimal Symbol – select (.) instead of (,).
