- Put scan tool in ohmmeter mode. Using scan tool, check resistance of PCM connector terminal No. 66 Yellow/White wire (FJ22 body) or White/Orange wire (JA body). If resistance is more than 5 ohms, go to step 4). If resistance is less than 5 ohms, go to next step.
- Disconnect speed proportional steering module connector. Inspect module connector terminals. Repair as required. Perform TEST VER-2 . If module connector is okay, go to next step.
- Using an external ohmmeter, check resistance of Yellow/White wire (FJ22 body) or White/Orange wire (JA body) between PCM connector terminal No. 66 and TCM connector terminal No. 58. If resistance is more than 5 ohms, replace speed proportional steering module. Perform TEST VER-2. If resistance is less than 5 ohms, repair short to ground in appropriate wire. Perform TEST VER-2.
- Using an external ohmmeter, check resistance of Yellow/White wire (FJ22 body) or White/Orange wire (JA body) between PCM connector terminal No. 66 and TCM connector terminal No. 58. If resistance is more than 5 ohms, repair open in appropriate wire. Perform TEST VER-2. If resistance is less than 5 ohms, replace PCM. Perform TEST VER-2 .
