Light emitting diode (LED) STATUS light operation/diagnostic codes:
• Solid RED indicates powered on/no input signals present (normal for key on/engine off)
• Solid GREEN indicates the TRG-002 has a valid crankshaft and camshaft signal and is in
synchronized operation
• Blinking RED indicates no crankshaft signal in with a camshaft signal detected
• Check connections at the crankshaft sensor. Check the tachometer or the engine RPM with a
scan tool while cranking the engine. If no RPM is shown while cranking then the TRG-002 is
not outputting a crankshaft signal.
• Blinking GREEN indicates no camshaft signal in with a crank signal detected
• The engine should start but you may sometimes have to crank the engine for a long time
before it starts. You most likely do not have a proper camshaft sensor signal into the TRG-
002. Check camshaft sensor connections and wiring pin-outs.
• The ECM/PCM should set a camshaft sensor DTC.
• Blinking RED RED RED GREEN (three red blinks followed by a green blink) indicates the
TRG-002 lost crank synchronization and recovered
• Usually due to electrical noise or bad sensor/wiring.
• Blinking GREEN GREEN GREEN RED (three green blinks followed by a red blink) indicates
a loss of camshaft signal.
• Usually due to electrical noise or bad sensor/wiring.
• The TRG-002 will blink either of these two last error codes on the three (3) power up cycles
after the problem occurs. If the error does not occur again during those three power ups then the
code will clear. If another code occurs prior to the code clearing, the older code will be cleared
and the new code will be stored and displayed.
Troubleshooting:
• If the TRG-002 RED LED does not come on when you turn on the ignition, check the power and
ground wire connections (red and black wires). No RED LED indicates no power to the TRG-
002.
• The production 24X engine crankshaft and camshaft harness power feeds are 12VDC. On key-on
you should be able to measure 12VDC between power and ground pins from the engine harness
for the crankshaft and camshaft sensors.
• The output from the TRG-002 (for the 58X type sensors) is 5VDC.
• The harness wire colors and signals/voltages are labeled in the wiring diagrams found on page
10.
