1. Disconnect the battery negative cable 2. Install the male end of the J 38758 to the negative battery terminal. 3. Turn OFF the test switch. 4. Install the negative battery cable to the female end of the test switch. 5. Install the Scan Tool (or equivalent) or wait for 20 minutes. 6. Turn ON the test switch. 7. Road test the vehicle while activating all accessories, including the radio and the air conditioning. 8. Lower the door glass, then exit the vehicle. Do not move the door handle after closing the door. 9. Open the hood. Important The power down timer will reset to 20 minutes if any wake up inputs are received by a Class 2 device (after the scan tool has put all Class 2 devices to sleep). 10. Put all of the Class 2 devices into the sleep mode. 11. Turn OFF the ignition switch. Remove the key. Important From this point on, electrical continuity must be maintained in the ground circuit of the battery through the Test Switch J 38758 in the ON position or through the ammeter J 39200 . 12. Components such as PCM, VCM, Automatic Air Conditioning, and the Truck Body Control Module have timers that draw several amps of current while they cycle down. This can give a false parasitic drain reading. Wait 20 minutes for these components to power down before continuing this test (or use the scan tool to put all Class 2 devices to sleep). 13. Connect a jumper wire with a 10 A fuse J 36169-A to the terminals of the test switch. 14. Turn the test switch to the OFF position. 15. Wait ten seconds. If the fuse does not blow, the current is less than 10 A. The ammeter can be used safely. 16. Before the fused jumper wire is removed, turn the test switch to the ON position. Important If an ammeter other than the J 39200 is used, ensure that the vehicle does not have a high current drain that would damage the ammeter when connected to the circuit. 17. Perform the following procedure in order to detect a high current drain: A. Set the ammeter J 39200 to the 10 A scale. B. Connect the ammeter to the test switch terminals. C. Turn OFF the test switch. This allows the current to flow through the ammeter. D. Wait one minute, then inspect the current reading. Ñ When there is a current reading of 2 A or less, turn ON the test switch, this maintains continuity in the electrical system. Ñ Then, switch the meter down to the 2 A scale, for a more accurate reading, when the test switch is reopened. E. Open the test switch. F. Take the reading in milliamps. G. Note the battery reserve capacity. Refer to Battery Usage . Ñ Divide this number by 4. Example: 90/4 = 22.5 Ñ Compare this to the ammeter reading. Ñ The current drain in milliamps should not exceed this number. Ñ Example: if a battery has a reserve capacity of 90 minutes, the current drain should not exceed 22 milliamps. H. When the current draw is too high, remove the electrical system fuses one at a time until the draw returns to a value less than or equal to specifications. Ñ Start with the fuses that are hot all the time. Ñ To remove the fuse, you must first open the door, which causes a high enough current flow to damage the ammeter. Ñ Protect the ammeter, without disturbing the electrical continuity, by turning ON the test tool before opening the door. Ñ Remove the courtesy lamp fuse. Ñ Note the ammeter reading. Ñ If the parasitic load is still excessive, start removing the remaining fuses one at a time. Ñ Keep the courtesy lamp fuse out during diagnosis, so the door can remain open. Ñ Perform Steps 11 through 13 each time a fuse is removed. I. Removing the PCM or VCM fuse should cause a drop of less than 10 milliamps. A drop greater than 10 milliamps indicates a possible short to ground. J. Check the orange wires along with the components connected to the orange wires. No drop in the milliampere reading indicates the PCM or VCM is not drawing current. K. Repeat the parasitic current drain test procedure after any repair has been completed. L. When the cause of the excessive current draw has been located and repaired, remove the ammeter and the parasitic draw test switch.

TROUBLE SHOOTING NOTE: See TROUBLE SHOOTING – BASIC PROCEDURES article in GENERAL INFORMATION. 1) If a no-start condition exists and battery is known to be good, connect test light or voltmeter between starter solenoid terminal No. 50 and ground. See Figs. 6 and 7. 2) Turn ignition switch to START position. If test light or voltmeter does not indicate voltage, check main fusible links and large ampere main fuses in engine compartment relay box. If fusible links and fuses are okay, see IGNITION SWITCH CONTINUITY TEST and/or STARTER RELAY TEST under ON-VEHICLE TESTING. ON-VEHICLE TESTING NOTE: Before testing, ensure battery is fully charged, battery cables and terminal ends are tight and clean, and engine grounds are secure. CLUTCH START SWITCH TEST 1) Switch is located above clutch pedal on bracket. Disconnect wiring harness connector from switch. 2) Connect ohmmeter probes to switch terminals. Depress clutch pedal. If continuity does not exist, adjust or replace clutch start switch. If continuity exists, check circuit to starter relay for open, and check starter relay. See STARTER RELAY TEST. CLUTCH START CANCEL SWITCH TEST 1) Locate switch in left dash panel. Remove right lower instrument panel to access switch connector. Disconnect wiring harness connector from switch pigtail connector. See Fig. 1. 2) Connect negative lead of ohmmeter to terminal No. 1. Ensure continuity does not exist between connector terminals No. 1 and 2, terminals No. 1 and 3, and terminals No. 2 and 3. Check operation of switch by connecting jumper wires from 12-volt battery. Connect positive lead to terminal No. 3 and negative battery lead to terminal No. 1. 3) Using ohmmeter, ensure continuity does not exist between connector terminals No. 1 and 2 until switch button is pushed. When switch button is pushed, switch light should come on and continuity should exist. Disconnect battery and ensure continuity does not exit between terminals No. 1 and 2. If switch does not test as specified, replace switch. Fig. 1: Identifying Clutch Start Cancel Switch Connector Terminals Courtesy of Toyota Motor Sales, U.S.A., Inc. IGNITION SWITCH CONTINUITY TEST WARNING: Deactivate air bag system before performing any service operation. For 1996 4Runner, see AIR BAG RESTRAINT SYSTEM article. 1995 1) Disconnect negative battery cable. Removedriver’s lower instrument panel cover. Remove upper and lower steering column covers if needed. Locate ignition switch wiring harness 8-pin connector. See Figs. 2-3. 2) With ignition switch in LOCK position, there should be no continuity between any terminals. With ignition switch in ACC position, there should be continuity between terminals No. 2 and 3. With ignition switch in ON position, there should be continuity between terminals No. 1, 2 and 3, and between terminals No. 7 and 8. 3) With ignition switch in START position, there should be continuity between terminals No. 1, 4 and 6, and between terminals No. 7 and 8.

Procedures 1. Disconnect the alternator and the Powertrain Control Module (PCM). Check the Violet (VT) (GENerator MONitor or GENMON) wire from the alternator to pin 20 of the PCM connector and the Red/Pink (RD/PK) (GENerator COMmand or GENCOM) wire from the alternator to pin 45 of the PCM for high resistance, an open, or a short to ground. Repair the wiring as needed. 2. If the wiring checks OK, reconnect the PCM and alternator. Start the engine and monitor the VT wire for a roughly 0-10v square wave signal. The signal will be around 40-50% normally with no loads on the system and minimal charging system output. As the load increases, the duty cycle should increase (NOTE: the duty cycle is a positive duty cycle so as the duty cycle increases, the voltage high time increases). 3. If there is no signal on the wire, disconnect the alternator and with key on check the VT wire for roughly 9-10v from the PCM. If OK, jump the Orange/Light Blue (OG/LB) wire to battery voltage and recheck operation with everything connected. This wire should be battery voltage at all time. If the OG/LB wire has battery voltage, the VT wire shows voltage from the PCM but there is no signal on it with the alternator charging, suspect a faulty, defective or incorrect alternator
