Toyota Startlet 1996-1999 Obd1-Diy Diagnostic Tutorial

 

General information
Trouble codes are displayed by the malfunction indicator lamp (MIL).
Late models: The ECM fault memory can also be checked using diagnostic equipment connected to the data link connector (DLC).

Accessing

Normal mode
1 Switch ignition ON.
2 Bridge data link connector (DLC) terminals E1 and TE1. SOHC: Fig. 1 . DOHC: Fig. 2 . If no trouble codes are stored, the lamp will flash twice per second Fig. 3 .
3 Each trouble code consists of two groups of one or more flashes Fig. 4 [A]. Warning lamp flash duration: 0,5 second Fig. 4 [B].
4 A 0,5 second pause separates each flash Fig. 4 [C].
5 A 1,5 second pause separates each trouble code group Fig. 4 [D]. A 2,5 second pause separates each trouble code Fig. 4 [E].
6 For example: Two 0,5 second flashes – 1,5 second pause – one 0,5 second flash. Trouble code 21 displayed Fig. 4 – oxygen sensor (O2S)/heated oxygen sensor (HO2S).
7 Trouble codes are repeated 4,5 seconds after last trouble code.
9 Count MIL flashes. Note trouble codes. Compare with trouble code table. Remove bridge wire.
10 Switch ignition OFF. Rectify faults as necessary.

Test mode – DOHC
1 Switch ignition OFF.
2 Bridge data link connector (DLC) terminals E1 and TE2 Fig. 2 . Switch ignition ON.
3 Ensure malfunction indicator lamp (MIL) flashes four times per second. Start engine.
4 Drive vehicle at over 6 mph (10 km/h). Stop vehicle. Do not switch ignition OFF.
5 With data link connector (DLC) terminals E1 and TE2 bridged, bridge terminals E1 and TE1 Fig. 2 . Count MIL flashes. Note trouble codes. Compare with trouble code table.
6 Switch ignition OFF. Remove bridge wires. Rectify faults as necessary.

Isuzu VehiCross OBD 1 Manual Diagnostic Guide

The Isuzu VehiCROSS is a compact SUV from Isuzu. Produced from 1997 (Japanese market 1997-1999) through 2001 (US market 1999-2001), it shares much of its components with the Trooper, including both its 3.2 L and 3.5 L V6 engine that produces 215 bhp (160 kW; 218 PS) at 5400 rpm and 230 lb·ft (312 N·m) at 3000 rpm of torque. The vehicle also features the Torque on Demand (TOD) 4-wheel-drive system produced by BorgWarner. It is a small, sporty 2-door crossover vehicle with aggressive external styling, including short overhangs, an aggressive forward stance, titanium “teeth” in the grille, a black hood-insert, and black plastic cladding over the entire lower half of the vehicle. The US VehiCROSS came equipped with 16″ polished wheels in 1999 and 18″ chrome wheels during the remainder of production. The Japanese version came equipped with 16″ alloys with chrome center caps.

The VehiCROSS combined a computer-controlled AWD system for on-road driving and a locked-differential low-gear 4WD system for off-road driving. The Japanese version offered a 2WD non TOD or 4WD TOD option. The US-only constant 4WD TOD, with 12 independent sensors for detecting wheel spin and capable of redirecting power to the wheels with the most traction, gives the VehiCROSS a high level of traction on wet and icy roads. It also has a high level of performance for its height. While possessing on-road nimbleness, its body-on-frame truck construction, suspension and 4WD gearing make it very capable off-road.

Sales were intentionally limited, with only 5958 vehicles being produced between 1997 and 2001; 1805 were produced for the domestic Japanese market and the remaining 4,153 sold in the United States. Japanese sales were limited by the fact that the exterior width dimensions were not in compliance with Japanese Government dimension regulations, and the engine displacement obligated Japanese drivers for higher levels of annual road tax. The vehicle had a base price of $28,900.

PLEASE FOLLOW THE JUMPER SETTING ABOVE:

INSTRUCTION:

1. If possible run the engine to bring the oxygen sensor up to operating temperature then switch the engine off.
2. Connect the terminals using your own jumper wire, as shown in the diagram above.
3. Turn ignition ON, the Check Engine Light (CEL) should be flashing on your car dashboard

READING CODE INSTRUCTION
The fault code will be in one of the following Code Formats above.
Each code is made up of two series of flashes.
• The first series indicates the ‘tens’ digit.
• The second series indicates the ‘ones’ digit.
• A long pause separates each code.
• A shorter pause separates the ‘tens’ and ‘ones’.
• Upper Code Format Diagram shows code No. 32 in this format.
