STEP
INSPECTION
ACTION
TB3
CHECK HARNESS CIRCUIT(S) FOR SHORT TO
GROUND
• Key off.
• Breakout box installed, PCM disconnected.
• Disconnect O/D OFF switch. Inspect both ends
of the connector for damaged or pushed out
pins, moisture, corrosion, loose wires, etc.
Service as necessary
• Measure resistance between test pin 29 and
test pins 24/77 at the breakout box.
Is the resistance greater than 10,000 ohms?
Yes
Go to next step.
No
Service short circuit.
Rerun KOER self-test.
TB4
CHECK CONTINUITY OF O/D OFF SWITCH
HARNESS
• Key off.
• Breakout box connected, PCM disconnected.
• Measure the resistance between keypower at
the fuse panel and power side of O/D OFF
switch vehicle harness connector (ohmmeter
negative probe).
• Measure resistance between test pin 29 and
signal side of O/D OFF switch vehicle harness
connector.
Is resistance less than 5.0 ohms?
Yes
Go to next step.
No
Service open circuit.
Remove breakout box.
Reconnect all components.
Rerun OBD test.
TB5
CHECK HARNESS CIRCUIT FOR SHORT TO
POWER
• Key off.
• Breakout box installed, PCM disconnected.
• Measure resistance between test pin 29 and
test pins 71/97 at the breakout box.
Is each resistance greater than 10,000 ohms?
Yes
Replace damaged switch.
Remove breakout box.
Reconnect all components.
Rerun OBD test.
No
Service short circuit.
Remove breakout box.
Reconnect all components.
Rerun OBD test.
TB6
O/D OFF INDICATOR LIGHT ALWAYS ON
• Key on engine off.
• Cycle O/D OFF switch.
Does O/D OFF indicator light turn on and off?
Yes
Reconnect all components.
Unable to duplicate or identify fault at this time.
Intermittent poor connection or component malfunction
(Repair or replace as necessary).
No
Go to next step.
TB7
CHECK FOR SHORT TO GROUND IN O/D OFF
INDICATOR LIGHT CIRCUIT
• Key off.
• Disconnect PCM. Inspect both ends for
damaged or pushed out pins, moisture,
corrosion, loose wires, etc. Service as
necessary.
• Key on, engine off.
Does O/D OFF indicator light remain on?
Yes
Repair short to ground between bulb and test pin 79.
Verify O/D OFF indicator light turns on and off.
No
O/D OFF indicator light turns off when PCM is
disconnected replace PCM.
TB8
O/D OFF INDICATOR LIGHT NEVER ON
• Run key on engine running (KOER) self-test.
• Connect NGS tester to DLC.
Is D TC P 1780 present?
Yes
Service DTC P1780.
Go to TB1.
No
Go to next step.
TB9
CHECK CONTINUITY OF O/D OFF INDICATOR
LIGHT CIRCUIT
• Key off.
• Breakout box installed.
• Key on, engine off.
• Measure the voltage between test pin 79 and
test pins 24/76 at the breakout box.
Is the voltage reading greater than 2.0 volts?
Yes
Replace PCM.
Cycle (O/D OFF switch) checking operation of O/D OFF
indicator light.
No
Check indicator bulb and fuse.
If okay, open is in the wiring between the ignition switch
and test pin (79) at the harness connector.
Repair as necessary.
