Disconnect C156. KEY OFF. DO NOT depress brake pedel. On the IP Harness side measure for continuity between C156_N and C156_P. If NO continuity exist suspect T/S SW, wires or connector on the steering column. If continuity does exist wires are shorted within the IP Harness.

The STOP/TURN circuit is a strange circuit. It has two (2) B+ feeds. 1.Brake SW B+ feed. 2.T/S flasher B+ feed. Each B+ feed is determined by the position of the T/S SW. You either have a faulty T/S SW or the Brake SW B+ feed is shorted to the RH side STOP/TURN circuit. I'll keep looking to see if there's anyway to prove out one or the other.

I'm not sure about this but its easy enough to try: KEY OFF. Depress brake pedal. Using T/S SW set to RH side, can you turn OFF the RH rear bulbs? Try same thing for the LH side.

Well deserved.

Using my desktop keyboard: Goto Bottom=End key Goto Top=Home key

Could that be the Pulse Width Modulation (PWM) controller, if equipped.

I wonder if the coolant temperature sensor for the fans have anything to do with this?

Is KEY ON, KEY OFF or it doesn't matter?

I think weather conditions are for both the launch and the landing of the Falcon 9 somewhere out in the Atlantic.

O2 Heater Relay shown in the schematic is incorrect. Two (2) pins are labeled wrong. Should be as follows: C228_1(30)(ORN) from Fuel Pump Relay C216_4(87). C228_5(86)(YEL) from IGN SW C267_I1. As for O2 Heater Relay function when O2 Heater Relay is OFF (deactivated), O2 Heater element is ON. Now when the ECU see a WOT condition, O2 Heater Relay is turned ON (activated) allowing for full battery voltage to bypass the Fuel Pump Ballast Resistor and supply that voltage directly to the Fuel Pump Motor. Should also mention Fuel Pump Ballast Resistor is bypassed during engine CRANK. Starter Relay C378_BAL.

Thanks. I was wondering if INJ was Duty Cycled instead of a direct ON/OFF pattern. All MS1700 testers I know of are in the dumpster. Well maybe a few members have one.

Does that 2.5L TBI Operation/Diagnosis manual show INJ PW displayed on a screen/oscilloscope pattern anywhere?

Payroll time well spent. Look like BANDED GLASS DRIVER COMP = GDA

@fiatslug87 nice job. I didn't know you hand typed them into EXCEL.

Two (2) descriptions for the same code. Could be true. GCF: BANDED GLASS DRIVER COMP or FULL DOOR

Two (2) codes for the same engine. Could be true. ENG 5.2L 8 CYL 2 BBL GAS: ELA ELD

Error is in the schematic. Can't see your photo, but if its as follows, its correct. 30 - ORN 85 - GRY/YEL 86 - YEL Yes

@eaglescout526 could it be someone else has found another use for the Engine Compartment Lamp connector?

What about the earliest 4.0L

Understood.
