1998 – 2000 MODELS 1. Inspect main ground points (refer to SB99*04*S001 for more information). * P6 ground point-body [on the passenger side of engine compartment, between the battery and cruise control actuator (if equipped)]. (Figure Fig. 1 ) * P10 ground point-engine (at the alternator bracket) . (Figure Fig. 2 ) Isuzu: 1998 – 2000 Rodeo AFFECTED VEHICLES:1998 – 2000 Rodeo (UE)/Amigo (UA) models with 3.2L V6 engines NOTE: Please refer to the appropriate workshop manual for the correct diagnosing procedure and/or follow the service procedures outlined in this bulletin for the vehicle being serviced. NOTE: The 1998, 1999 or 2000 Rodeo/Amigo Electrical Troubleshooting Manual can assist in locating the vehicle ground distribution (i.e., ground contact points). * Perform a voltage drop test at the main ground points. * If the voltage drop test fails, then inspect and clean both the bolt and contact point. * Verify and correct idle settings (if needed) as described in the workshop manual. * If the repair procedure on this step solves the high idle condition, then return the vehicle to the customer. If the repair procedure on this step does not solve the high idle condition, then go to step 2 (16 pin Blue Connector). B. Remove P-6/P-10 ground terminal and bolt for ground contact inspection. * Inspect ground contact area for corrosion. * Inspect bolt and thread for damage or corrosion. * Clean the ground area and fastening bolt thoroughly with a wire brush. * Replace bolt if damaged or heavily corroded. C. Install the P-6/P-10 ground terminal and bolt (tighten using hand tools only). * Torque the P-6/P-10 ground terminal bolt to (14 N.m) 10 lb.ft. 1998 – 1999 MODELS ONLY 2. Inspect the 16 pin blue connector, located under the power steering fluid reservoir for corrosion, bent, or damaged pins (specifically for the Throttle Position Sensor). (Figure Fig. 3 )


TIMING BELT Removal 1. Disconnect negative battery cable. Remove air cleaner assembly. Remove upper fan shroud. Remove cooling fan assembly. Remove all accessory drive belts. 2. Remove fan pulley assembly. Remove crankshaft pulley bolt. Using Puller (J-8614-01) or equivalent, remove crankshaft pulley. Remove oil cooler hose from timing cover. Remove timing belt cover. Align all timing marks prior to belt removal. See Fig. 1 – Fig. 4 . Remove belt tensioner pusher and timing belt. Fig. 1: Aligning Timing Belt Sprockets (DOHC) Courtesy of ISUZU MOTOR CO. Installation 1. Ensure all timing marks are aligned. Install belt over one pulley at a time starting at crankshaft sprocket and working counterclockwise. Belt should go over tensioner last. Secure belt at each pulley during installation with pinch clips. See Fig. 5 . 2. Compress timing belt tensioner pusher and insert pin to retain pusher. Apply pressure to tensioner against belt, and install tensioner pusher. Tighten bolts to specification. See TORQUE SPECIFICATIONS . 3. Loosen tensioner pulley bolt. Apply pressure on belt by rotating tensioner. Tighten tensioner pulley bolt to specification.. See TORQUE SPECIFICATIONS . Remove pin from timing belt tensioner pusher. 4. Remove pinch clips from timing belt (if used). Install crankshaft pulley, tightening center bolt finger tight. Rotate crankshaft 2 turns clockwise. Ensure timing belt tensioner pusher rod protrudes proper

Line Pressure Check Procedure Tools Required Important: Before performing a line pressure check, verify that the pressure control (PC) solenoid valve is receiving the correct electrical signal from the PCM. Caution: Keep the brakes applied at all times in order to prevent unexpected vehicle motion. Personal injury may result it the vehicle moves unexpectedly. J 21867Universal Pressure Gauge Set 1. Install a Scan Tool. 2. Start the engine and set the parking brake. 3. Check for a stored Diagnostic Trouble Code (DTC). 4. Repair the vehicle, if necessary. 5. Check the fluid level. Refer to the Transmission Fluid Checking Procedure. 6. Check the manual linkage for proper adjustment. 7. Turn the engine OFF. Remove the oil pressure test hole plug and install the J 21867. 8. Put the gear selector in PARK range and set the parking brake. 9. Start the engine and allow the engine to warm up at idle Notice: Total test running time should not be longer than two minutes, or else transmission damage could occur. Notice: Refer to Fastener Notice in Cautions and Notices. Parts Information 10. Access the PC solenoid valve control test on the Scan Tool. Zoom Sized for Print 11. Increase the PC solenoid as shown actual current from 0.0 to 1.0 amps in 0.1 amp increments. Allow the pressure to stabilize for five seconds after each pressure change. Read the corresponding line pressure on the J 21867. 12. Refer to the Line Pressure specification table. Compare the data to the table. 13. If pressure readings differ greatly from the table, refer to Incorrect Line Pressure. 14. Remove the J 21867. 15. Apply sealant, P/N 12345382 (in Canada, P/N 10953489), to the oil pressure test hole plug. 16. Install the oil pressure test hole plug. Tighten Tighten the oil pressure test hole plug to 12 N.m (106 lb in).

High Tension Wire Resistance 1. Set ohmmeter to x 1000 range and attach leads to each end of high tension wire. On Isuzu I’Mark and P’UP, resistance should not exceed 73,500 ohms per foot. 2. On all other models, resistance should not exceed 25,000 ohms per wire. If it does, replace wires. Fig. 5: Checking Pick-Up Coil Resistance Connect ohmmeter leads to distributor connector terminals. Pick-Up Coil Resistance Set ohmmeter to x 100 range, measure pick-up coil resistance at distributor connector. See Fig. 5 and PICK-UP COIL (SIGNAL GENERATOR) RESISTANCE table. Also check wires for shorts or opens. PICK-UP COIL (SIGNAL GENERATOR) RESISTANCE (OHMS) NOTE: On Toyota Celica, Starlet, 4Runner and Pickup models, a signal generator is used in place of a pick-up coil. Application

1. Look at the BARO PID. Refer to the Barometric Pressure Reference Chart in this article. At sea level, BARO should read about 159 Hz (29.91 in. Hg). As a reference, Denver, Colorado at 1524 meters (5000 ft.) altitude should be about 144 Hz (24.88 in.Hg). Normal learned BARO variability is up to +/- 6 Hz (+/- 2 in. Hg.). If BARO indicates a higher altitude than you are not at (7 or more Hz lower than expected), you may have MAF contamination. If available, Service Bay Diagnostic System (SBDS) has a Manifold Absolute Pressure (MAP) sensor that can be used as a barometric pressure reference. Use “MAP/BARO” test under “Powertrain,” “Testers and Meters.” Ignore the hookup screen. Connect GP2 to the reference MAP on the following screen. 2. On a fully warmed up engine, look at Long Term Fuel Trim at idle, in Neutral, A/C off, (LONGFT1 and/or LONGFT2 PIDs). If it is more negative than -12%, the fuel system has learned lean corrections which may be due to the MAF sensor over-estimating air flow at idle. Note that both Banks 1 and 2 will exhibit negative corrections for 2-bank system. If only one bank of a 2-bank system has negative corrections, the MAF sensor is probably not contaminated. 3. On a fully warmed up engine, look at MAF voltage at idle, in Neutral, A/C off (MAF V PID). If it’s 30% greater than the nominal MAF V voltage listed in the Powertrain Control/Emissions Diagnosis (PC/ED) Diagnostic Value Reference Charts for your vehicle, or greater than 1.1 volts as a rough guide, the MAF sensor is over-estimating air flow at idle. 4. If at least tow of the previous three steps are true, proceed to disconnect the MAF sensor connector. This puts the vehicle into Failure Mode and Effects Management (FMEM). In FMEM mode, air flow is inferred by using rpm and throttle position instead of reading the MAF sensor. (In addition, the BARO value is reset to a base/unlearned value.) If the lean driveability symptoms go away, the MAF sensor is probably contaminated and should be replaced. If the lean driveability symptoms do not go away, go to the PC/ED Service Manual for the appropriate diagnostics.
