(1) See 1A: ENTERING DIAGNOSTICS under PRELIMINARY TESTS in DIAGNOSIS - AW4 article.
(2) Check cooling system and thermostat if engine coolant temperature does not reach 176°F (80°C) after driving 20 minutes.
(3) This DTC can be set by low fuel level. Ensure fuel tank is at least 1/4 full and retest for DTC.
(4) Replace Powertrain Control Module (PCM) and perform TEST VER-2A.
(5) On AB body, perform TEST TC-135A. On all other bodies, perform TEST TC-36A.
