The ATF level gauge (dip-stick) has been discontinued, and the ATF inspection method and the oil level inspection method have been changed. This mechanism consists of a refill plug, overflow plug, ATF temperature sensor No.2, and A/T OIL TEMP temperature warning light. ATF Filling procedures using SST (09843-18020): When a large amount of ATF needs to be filled (i.e. after removal and installation of oil pan or torque converter), perform the procedure from step 1. When the small amount of ATF is required (i.e. removal and installation of the oil cooler tube, repair of oil leak), perform the procedure from step 7. 1) Raise the vehicle keeping it level. 2) Remove the refill plug and overflow plug. 3) Fill ATF from the refill plug until it overflows from the overflow plug. 4) Install the overflow plug. 5) Fill the specified amount of ATF determined by procedure and install the refill plug. Example 6) Lower the vehicle down. 7) Use the SST (09843-18020) to short the terminals Tc and CG of the DLC3 connector: 8) Start the engine and allow it to idle. A/C switch must be turned OFF. 9) Move the shift lever slowly through each of the positions from the P to the L position, and move it back to the P position. 10) Move the shift lever from the D position, and quickly move then back and forth between N and D (once per less than 1.5 seconds) for at least 6 seconds. This will activate the oil temperature detection mode. Standard: The A/T OIL TEMP warning light remains illuminated for 2 seconds and it goes off. 11) Return the shift lever to the P position and disconnect the terminal Tc. 12) Idle the engine to raise the oil temperature. 13) Immediately after the ATF OIL TEMP warning light turns on, lift the vehicle up. The A/T OIL TEMP warning light will indicate the ATF temperature according to the following table. (Insert table here) 14) Remove the overflow plug and adjust oil quantity. If the ATF overflows, go to step 17, and if the ATF does not overflow, go to step 15. 15) Remove the refill plug. 16) Fill ATF to the refill plug until it flows out from the overflow plug. 17) When the ATF flow slows to a trickle, install the overflow plug. 18) Install the refill plug (only if the refill plug has been removed). 19) Lower the vehicle down. 20) Turn the ignition switch OFF to stop the engine. For details about the ATF Filling procedures, see the 2004 4Runner Repair Manual (Pub. No. RM1059U)

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. If continuity is not as specified, replace switch.
