Fuel Pump Relay: Service Precautions
*** Green or Blue Relay Cautions TSB#NTB95-070 July 5, 1995
Relay Testing
When diagnosing at any green or blue colored relay (type 1M, 1 make-normally open relay), observe the following cautions to prevent damage to the
Engine Control Module
(ECM):
1. Note that the schematic on the fuel pump relay is rotated 90 degrees from the orientation of the relay terminals in the relay connector (see
diagram):
2. Exercise caution to ensure that the correct terminals are being probed at the relay connector during diagnosing/checking.
NOTE: Use a circuit tester first to verify the terminals that are supplied with battery voltage. If battery voltage is connected to terminal 2, the
ECM will be damaged if the circuit being tested has terminal 2 connected to the ECM.
