ON-VEHICLE INSPECTION
PROCEDURE
1. INSPECT DEF RELAY
| (a) Measure the resistance according to the value(s) in the table below. Standard Resistance: | Tester Connection | Condition | Specified Condition | | 3 - 4 | Auxiliary battery voltage applied between terminals 1 and 2 | 10 kΩ or higher | | 3 - 4 | Auxiliary battery voltage not applied between terminals | Below 1 Ω | | 3 - 5 | Auxiliary battery voltage applied between terminals 1 and 2 | Below 1 Ω | | 3 - 5 | Auxiliary battery voltage not applied between terminals | 10 kΩ or higher | | 4 - 5 | Always | 10 kΩ or higher | If the result is not as specified, replace the DEF relay. | |
2. INSPECT DEICER RELAY
| (a) Measure the resistance according to the value(s) in the table below. Standard Resistance: | Tester Connection | Condition | Specified Condition | | 3 - 5 | Auxiliary battery voltage applied between terminals 1 and 2 | Below 1 Ω | | 3 - 5 | Auxiliary battery voltage not applied between terminals | 10 kΩ or higher | If the result is not as specified, replace the deicer relay. | |
3. INSPECT HWD RELAY
| (a) Measure the resistance according to the value(s) in the table below. Standard Resistance: | Tester Connection | Condition | Specified Condition | | 3 - 5 | Auxiliary battery voltage applied between terminals 1 and 2 | Below 1 Ω | | 3 - 5 | Auxiliary battery voltage not applied between terminals | 10 kΩ or higher | If the result is not as specified, replace the HWD relay. | |

DESCRIPTION HINT: Although the DTC titles say oxygen sensor, these DTCs relate to the air fuel ratio sensor. The air fuel ratio sensor generates voltage* that corresponds to the actual air fuel ratio. This sensor voltage is used to provide the ECM with feedback so that it can control the air fuel ra
TERMINALS OF ECU CHECK SLIDING ROOF ECU (SLIDING ROOF DRIVE GEAR SUB-ASSEMBLY) (a) Disconnect the P22 sliding roof ECU (sliding roof drive gear sub-assembly) connector. (b) Measure the resistance and voltage according to the value(s) in the table below. HINT: Measure the values on the wire harness
