B. How to connect OBD I Diagnostic Port The OBD I connector, which was set up to cater for older models of various car brands, has very few current applications as most older cars have been phased out. Cars that produced after 2005 are basically all OBD II connector. In USA, we still occasionally come across vintage or modified cars that still use OBD I. For this reason, a transfer from OBD II to OBD I is required.
OBD I Connector
Diagnostic Extension Cable
OBD Connector
Note: when using older models, the Transfer Cable must be used, with the small power connector on it, which is connected to the power connector of the power double clamp cable, this is a solution for certain cars before 1996, whose diagnostic holders do not have a 12V power supply.
All other configurations with non-16PIN diagnostic connectors can be wired as shown in Picture for achieving the diagnosis of the corresponding old models.

3.3 Maintenance
Dollarfix PF8 supports common maintenance and reset functions, namely, Oil Reset, Elec. Throttle Adaption, IMMO Service, Injector Coding, Brake-pad Reset, Steering Angle Reset, ABS Bleeding, AFS Reset, Battery Matching, A/T Learning, DPF Regeneration, EGR Adaption, TPMS Reset, Sunroof Initialization, Suspension Matching, Gear Learning, Airbag Reset, ODO Reset, AdBlue Reset, A/F Reset, Coolant Bleeding, Language Change, NOx Sensor Reset, Seat Calibration, Stop/Start Reset, Transport Mode, Tyre Reset, Windows Calibration, Clutch Matching, ECU Reset, FRM Matching, Gateway Module Data Calibration, Rainfall Light Sensor, Turbocharging Matching.
3.3.1 Oil Reset The lightening of the car maintenance light indicates that the vehicle needs maintenance. Reset the mileage or driving time to zero after the maintenance, so the maintenance light will go out and the system will start a new maintenance cycle.
3.3.2 Elec. Throttle Adaption
18
Elec. Throttle Adaption is to utilize the car decoder to initialize the throttle actuator so that the learning value of the ECU returns to the initial state. By doing these, the movement of the throttle (or idle motor) can be more accurately controlled, thus adjust the intake volume. Situations when throttle matching is needed: a. After replacing the electronic control unit, the relevant characteristics of the throttle
operation have not been stored in the electronic control unit. b. After the electric control unit is powered off, the memory of the electric control unit’s
memory is lost. c. After replacing the throttle assembly, you need to match the throttle. d. After replacing or disassembling the intake port, the controlling of the idle speed by the
coordination between the electronic control unit and the throttle body is affected. e. Although the characteristics of the idle throttle potentiometer have not changed, the
intake volume has changed and the idle control characteristics have changed at the same throttle openings.
3.3.3 Steering Angle Reset To reset the steering angle, first find the relative zero-point position for the car to drive in straight line. Taking this position as reference, the ECU can calculate the accurate angle for left and right steering. After replacing the steering angle position sensor, replacing steering mechanical parts (such as steering gearbox, steering column, end tie rod, steering knuckle), performing four-wheel alignment, or recovering car body, you must reset the steering angle.
3.3.4 Battery Matching This function enables you to perform a resetting operation on the monitoring unit of vehicle battery, in which the original low battery fault information will be cleared and battery matching will be done. Battery matching must be performed in the following cases: a. Main battery is replaced. Battery matching must be performed to clear original low
battery information and prevent the related control module from detecting false information. If the related control module detects false information, it will invalidate some electric auxiliary functions, such as automatic start & stop function, sunroof without one-key trigger function, power window without automatic function. b. Battery monitoring sensor. Battery matching is performed to re-match the control module and motoring sensor to detect battery power usage more accurately, which can avoid an error message displaying on the instrument panel.
3.3.5 ABS Bleeding When the ABS contains air, the ABS bleeding function must be performed to bleed the brake system to restore ABS brake sensitivity. If the ABS computer, ABS pump, brake master cylinder, brake cylinder, brake line, or brake fluid is replaced, the ABS bleeding function must be performed to bleed the ABS.
3.3.6 Brake-pad Reset
19
If the brake pad wears the brake pad sense line, the brake pad sense line sends a signal sense line to the on-board computer to replace the brake pad. After replacing the brake pad, you must reset the brake pad. Otherwise, the car alarms. Reset must be performed in the following cases: a. The brake pad is replaced or brake pad wear sensor. b. The brake pad indicator lamp is on. c. The brake pad sensor circuit is short, which is recovered. d. The servo motor is replaced.
3.3.7 DPF Regeneration DPF regeneration is used to clear PM (Particulate Matter) from the DPF filter through continuous combustion oxidation mode (such as high temperature heating combustion, fuel additive or catalyst reduce PM ignition combustion) to stabilize the filter performance. DPF regeneration may be performed in the following cases: a. The exhaust back pressure sensor is replaced. b. The PM trap is removed or replaced. c. The fuel additive nozzle is removed or replaced. d. The catalytic oxidizer is removed or replaced. e. The DPF regeneration MIL is on and maintenance is performed. f. The DPF regeneration control module is replaced.
3.3.8 Gear Learning The crankshaft position sensor learns crankshaft gear machining tolerance and saves to the computer to more accurately diagnose engine misfires. If gear learning is not performed for a car equipped with Delphi engine, the MIL turns on after the engine is started. The diagnostic device detects the DTC P1336 ‘gear not learned’. In this case, you must use the diagnostic device to perform gear learning for the car. After gear learning is successful, the MIL turns off. After the engine ECU, crankshaft position sensor, or crankshaft flywheel is replaced, or the DTC ‘gear not learned’ is present, gear learning must be performed.
3.3.9 IMMO Service To prevent the car being used by unauthorized keys, the anti-theft key matching function must be performed so that the immobilizer control system on the car identifies and authorizes remote control keys to normally use the car. When the ignition switch key, ignition switch, combined instrument panel, ECU, BCM, or remote-control battery is replaced, anti-theft key matching must be performed.
3.3.10 Injector Coding Write injector actual code or rewrite code in the ECU to the injector code of the corresponding cylinder so as to more accurately control or correct cylinder injection quantity. After the ECU or injector is replaced, injector code of each cylinder must be
