INSPECTION
PROCEDURE
1. INSPECT CANISTER (CHARCOAL CANISTER ASSEMBLY)
| (a) Visually check the canister (charcoal canister assembly). (1) Visually check the canister (charcoal canister assembly) for cracks or damage. If cracks or damage are found, replace the canister (charcoal canister assembly). |
|
(b) Check canister (charcoal canister assembly) operation.
| (1) With the purge line port closed, blow 0.5 kPa (0.005 kgf/cm2, 0.1 psi) of air into the vent line port, and check that air flows from the air line port. If the result is not as specified, replace the canister (charcoal canister assembly). |
|
| (2) With the vent line port closed, blow 0.5 kPa (0.005 kgf/cm2, 0.1 psi) of air into the air line port, and check that air flows from the purge line port. If the result is not as specified, replace the canister (charcoal canister assembly). |
|
(c) Check for air leaks.
| (1) Connect a pressure gauge to the vent line port. |
|
(2) With the purge line port and air line port closed, apply 20 kPa (150 mmHg, 5.91 in. Hg) of pressurized air into the vent line port, then confirm that pressure is maintained for 1 minute.
If the result is not as specified, replace the canister (charcoal canister assembly).
2. INSPECT NO. 2 CHARCOAL CANISTER SUB-ASSEMBLY
| (a) Visually check the No. 2 charcoal canister sub-assembly. (1) Visually check the No. 2 charcoal canister sub-assembly for cracks or damage. If cracks or damage are found, replace the No. 2 charcoal canister sub-assembly. |
|
(b) Check No. 2 charcoal canister sub-assembly operation.
| (1) Blow 0.5 kPa (0.005 kgf/cm2, 0.1 psi) of air into the port A, and check that air flows from the port B. If the result is not as specified, replace the No. 2 charcoal canister sub-assembly. |
|
(c) Check for air leaks.
| (1) Connect a pressure gauge to the port A. |
|
(2) With the port B and leak detection pump sub-assembly connector closed, apply 20 kPa (150 mmHg, 5.91 in. Hg) of pressurized air into the port A, then confirm that pressure is maintained for 1 minute.
If the result is not as specified, replace the No. 2 charcoal canister sub-assembly.
(d) Check the leak detection pump sub-assembly.
| (1) Connect a positive (+) lead from the battery to terminal 5 and a negative (-) lead to terminal 1. |
|
(2) Check that a clicking sound is heard from the leak detection pump sub-assembly.
If the result is not as specified, replace the leak detection pump sub-assembly.

Side Camera RH Response Malfunction (C2A6C)
DESCRIPTION During self diagnosis of the parking assist ECU, the parking assist ECU sends display mode ID signals to the side television camera assembly RH. This DTC is stored when the output of the side television camera assembly RH does not match the expected output. DTC No. Detection Item
Engine Coolant Temperature Sensor 1 Circuit Short to Battery or Open (P011515)
DESCRIPTION Refer to DTC P011511. Click here HINT: When DTC P011515 is stored, the ECM enters fail-safe mode. During fail-safe mode, the engine coolant temperature is estimated to be 80°C (176°F) by the ECM. Fail-safe mode continues until a pass condition is detected. DTC No. Detection Item
