CHECK HARNESS FOR SHORT TO POWER
OR GROUND
• Key off.
• Breakout box installed, PCM disconnected.
Caution
• Removing the solenoid body connector by
prying with a screwdriver will damage the
connector. Remove the solenoid body
connector by pushing on the wire tab and
pulling on the wiring harness.
• Solenoid body connector disconnected.
• Refer to connector schematic and table of
solenoid body.
tr
Solenoid Body Connector Component
• Measure resistance between 3-2T/C C S
solenoid circuit test pin 102 and test pin 71/97
at the breakout box.
• Measure resistance between 3-2T/C C S
solenoid circuit test pin 102 and test pins
77/103, 91 at the breakout box.
• Is each resistance greater than 10,000 ohms?
Yes
Inspect PCM power relay, service as required. If okay,
replace PCM.
Rerun OBD test.
No
Service short circuit.
Remove breakout box.
Reconnect all componets.
Rerun OBD test.

DIAGNOSTIC TROUBLE CODE
P1780
• Diagnostic trouble code (DTC) P1780 indicates
the O/D OFF switch was not cycled during key
on engine running (KOER) Self-Test.
Possible cause:
• O/D OFF switch damaged or switch not
cycled during self-test
• Shorted harness
• Damaged PCM
Did O/D OFF switch cycled during KOER
self-test?
Yes
Go to next step.
No
Return KOER Self-Test to cycle O/D OFF switch.
TB2
CHECK O/D OFF SWITCH CIRCUIT FOR
VOLTAGE
• Key off.
• Disconnect PCM. Inspect for damaged or
pushed out pins, corrosion, loose wires, etc.
Service as necessary.
• Install breakeout box, leave PCM
disconnected.
• Key on engine off.
•
Measure voltage between test pin
29
and test
pins 24/77 at the breakout box while cycling
the O/D OFF switch several times
Does the voltage cycle?
Yes
Replace PCM.
Remove breakout box.
Rerun OBD test.
No
Go to next step.
