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 )

With the ignition switch in the RUN position, test for battery voltage at the circuit fuse in the transmission solenoid power supply circuit. Refer to the appropriate SI Document for the transmission solenoid power supply circuit information. 2. If battery voltage is present at the fuse, inspect the ignition voltage circuit between the fuse and the transmission for possible opens. 3. If battery voltage is not present at the fuse, test for continuity between the fuse and the ignition switch. If NO ontinuity is between the fuse and the ignition switch, repair the open in that circuit. 4. If you have continuity between the fuse and the ignition switch, the most likely cause is the ignition switch. Replace the ignition switch using the appropriate Ignition Switch Replacement procedure in SI. Refer to group number 2.188 of the parts catalog for part description and usage of the ignition switch.
