Can't supply a diagram but I can tell you that 15A fuse 27 in the central junction box (CJB) applies power via a LT BLU/PNK wire to terminal 2 (the coil) of the indicator flasher relay in auxiliary relay box 1. 20A fuse 18 in the CJB applies power via a LTGRN/RED wire to the brake pedal position switch and terminal 3 (the relay arm). Terminal 5 of the relay connects the relay coil to ground (BLK wire). Terminal 1 of the relay supplies power via the LT BLU wire to the turn signals when the relay is closed. Terminal 4 supplies power via the WHT/RED wire to the hazard light circuit when the relay is open.

Want to locate censor p0705 on a 2006 suzuki forenza


DTC P0705 - Transmission Range (TR) switch circuit malfunction (short to power supply)

DETECTION CONDITION
• Two or more range signals are input from the TR switch for 12 s or more.

Diagnostic support note:
• This is a continuous monitor (CCM).
• MIL illuminates if TCM detects the above malfunction condition in two consecutive drive cycles.
• PENDING CODE is available.
• FREEZE FRAME DATA is available.
• AT warning light illuminates.
• DTC is stored in TCM memory.

POSSIBLE CAUSE
• TCM malfunction
• Short to power supply in wiring harness between TR switch terminal A and TCM terminal 1D
• Short to power supply in wiring harness between TR switch terminal E and TCM terminal 2C
• Short to power supply in wiring harness between TR switch terminal D and TCM terminal 2B
• Short to power supply in wiring harness between TR switch terminal G and TCM terminal 2E
• Damaged connector between TR switch and TCM
• TR switch malfunction


Inspect swtich harnesses and test with OBD scanner reader tool.

P0703


The PCM monitors changes in input voltage from the brake switch. If the PCM does not detect PCM terminal 1AU voltage changes while alternately accelerating and decelerating 8 times, the PCM determines that brake switch circuit has malfunctioned.

• Brake switch malfunction
• Poor connection of brake switch connector or PCM connector
• Short to power supply in wiring harness between brake switch terminal D and PCM connector terminal 1AU
Open circuit in wiring harness between brake switch terminal D and PCM connector terminal 1AU
• Open circuit in wiring harness between battery positive terminal and brake switch terminal A
• PCM malfunction

Do you have an immobilizer on this truck? Possible short circuit? Do you have added trailer wiring on this truck? Possible short circuit? Are your brake lights working normally? If not, is the brake light fuze OK?

The wiper controls are not working but the other controls on the modual still work


assuming the fuse is good, you can test the wiper motor by applying ground and 12v from the battery directly to the wiper motor. ensure you have the correct terminals on the motor for ground and power. there will usually be 2 or 3 power terminals and 1 ground terminal which has a black wire connected to it. the other terminals are for the different speeds and supply different voltages. you can connect to any of these wires. if the motor works then the switch is bad.

Electronic Throttle Control


DTC P2106 Throttle actuator control system-forced limited power DETECTION CONDITION
• The PCM monitors the throttle actuator control current when the ignition switch is on. If the control current is less than 8 A or more than 11 A, the PCM determines that the throttle actuator control system is under forced limited power. Diagnostic support note
• This is a continuous monitor (CCM). • The MIL illuminates if the PCM detects the above malfunction condition in the first drive cycle. • PENDING CODE is available if the PCM detects the above malfunction condition. • FREEZE FRAME DATA is available. • The DTC is stored in the PCM memory. POSSIBLE CAUSE
• Throttle actuator malfunction • Connector or terminal malfunction • Open circuit in wiring harness between throttle body terminal A and PCM terminal 1B • Short to power supply in wiring harness between throttle body terminal A and PCM terminal 1B • Short to GND in wiring harness between throttle body terminal A and PCM terminal 1B • Open circuit in wiring harness between throttle body terminal B and PCM terminal 1C • Short to power supply in wiring harness between throttle body terminal B and PCM terminal 1C • Short to GND in wiring harness between throttle body terminal B and PCM terminal 1C • PCM malfunction
and for the other one

the dealers need to reflash the powertrain module ( ETC ) ...

hope i'll not get that problem on my 04 hemi...

84 bonneville fuel gage


You need to isolate what the problem is. First, check the power supply/ fuse for the instruments, ensure the gauge has a supply. Check the earthing at both the tank end and the gauge (body). With a meter, you should see 12V. (or maybe less, if the Bonneville has a regulator on the instruments, I don't specifically know the vehicle). This should appear between one of the rear terminals of the gauge and the case, when the ignition is on. If present there, check it is still there when checked between that terminal and another earth point on the car's metalwork.
The other terminal on the gauge is the transmitter termination. If the power is present, removing the transmitter wire should cause the gauge to either go full scale, or not move at all. Use a piece of wire to short this terminal to ground, the meter should do the opposite to the previous test. If no movement, the gauge is faulty. Replace.
At the tank end, you should find the transmitter unit. It should have a single wire connected to a terminal. Remove this. With aan ohmmeter, check for a resistance reading between this terminal and ground. If no meter, turn on the ignition with this wire disconnected, the gauge should do the same as it did when the wire was removed behind the gauge. If it does, short the removed wire of the transmitter to ground, the gauge should do the same as the short test at the gauge, If not, the wire is broken or shorted somewhere between the gauge and transmitter.
If the gauge moves as before when testing from the transmitter wire, most probably the transmitter is faulty.
Too hard? Leave it to the experts...!?! ;-]
