Camry & Camry Solara

If using scan tool, go to next step. If scan tool is not available, go to step 5.
Connect scan tool to data link connector No. 3. See Figure and Figure . Turn ignition on and then turn scan tool on. Read STA signal display on scan tool with ignition on and with ignition in START position and engine cranking. The STA signal display should read OFF with ignition on and ON with ignition in START position. If STA signal display is not as specified, go to next step. If STA signal display is as specified, diagnose by symptom. See TROUBLE SHOOTING - NO CODES article.
Check for open in wiring harness and electrical connectors between ECM and junction connectors J6 and J7. See appropriate wiring diagram in STARTERS article in STARTING & CHARGING SYSTEMS. ECM is located behind glove box. For illustration of ECM location, see THEORY & OPERATION article. Junction connectors J6 and J7 are located behind driver's side of instrument panel, near fuse/relay box. See Fig 1.
NOTE: Junction connectors J6 and J7 may also be referred to as junction connectors J7 and J8 when referring to wiring diagram.

If wiring harness or electrical connector are defective, repair as necessary. If wiring harness and electrical connectors are okay, check ECM ground circuit. See appropriate wiring diagram in WIRING DIAGRAMS article. If ECM ground circuit is defective, repair ground circuit as necessary. If ECM ground circuit is okay, replace ECM. On models equipped with engine immobilizer system, if ECM is replaced, ECM must be programmed with proper ignition key code for engine immobilizer system. For programming procedures, see COMPUTER RELEARN PROCEDURES article in GENERAL INFORMATION.

Remove glove box for access to ECM. For illustration of ECM location, see THEORY & OPERATION article. Note ECM electrical connector terminals. See Figure. Using voltmeter, check voltage between body ground and STA terminal at ECM with ignition in START position and engine cranking. See ECM TERMINAL IDENTIFICATION FOR STARTER SIGNAL (CAMRY & CAMRY SOLARA) table.
