2000 Mercedes-Benz ML320 3.2L 2001 Mercedes-Benz E320 3.2L 2001 Mercedes-Benz C240 2.6L 2001 Mercedes-Benz E320 4Matic 3.2L 2001 Mercedes-Benz C320 3.2L 2002 Mercedes-Benz ML320 3.2L Potential Causes: Pedal Sensor Throttle Body Wiring Tech Tips: With new sensor the throttle stops must be relearned. Use compatible scan tool and perform adaptations. ALWAYS verify charging system voltage is correct. Tests/Procedures: 1. Connect scan tool and monitor voltages of pedal sensor B37. Signal 1 (Accelerator pedal position: Idle speed):[0.2...0.5] V Signal 2 (Accelerator pedal position: Idle speed):[0.1...0.5] V Signal 1 (Accelerator pedal position:Kickdown):[4.3...4.8] V Signal 2 (Accelerator pedal position:Kickdown):[2.1...2.5] V 3. Test throttle body voltages with scan tool. Potentiometer #2 signal voltage ignition on, accelerator pedal position CTP 0.3-0.9 VDC, WOT > CTP value Potentiometer #1 signal voltage Ignition on, accelerator pedal position CTP 4.0-4.6 VDC, WOT < CTP value.

Powertrain DTC Summaries – OBD II FAULT DESCRIPTION MONITORING CONDITIONS CHECK ENGINE MIL (CK ENG) DEFAULT ACTION POSSIBLE CAUSES DTC Diagnostic Trouble Code. SYS The powertrain system with which the DTC is associated – EMS, TRANS, ABS/TC (DSC). DTC retrieval tools: OBD II – indicates that the DTC is an OBD II code and can be accessed via a generic scan tool or WDS. JAG – indicates that the DTC is not an OBD II code and is accessed only via WDS. Fault description. “DIAGNOSTIC MONITOR DRIVE CYCLE” for the particular DTC. Operate the vehicle as described to check for a reoccurrence of the DTC. Refer to pages 4 – 7. Use WDS Datalogger or Scan Tool to monitor specified engine parameter(s). 1 2 N OTHER Driver Warnings: N None R RED MIL / Message or Powertrain Warning Indicator A AMBER MIL / Message or Powertrain Warning Indicator C Charge indicator Control Module default action: Logged – DTC stored in ECM memory buffer; Flagged – DTC stored in ECM memory / CHECK ENGINE MIL activated. CM PIN ECM (SYS – EMS) / TCM (SYS – TRANS) Connector pin number(s) Possible causes are listed in the order of diagnostic checking. HIGH VOLTAGE – High voltage can be either sensor supply voltage (5 volts) or B+ voltage. 1 TRIP – indicates that the CHECK ENGINE MIL is activated by a fault occurring during ONE “TRIP”. 2 TRIPS – indicates that the CHECK ENGINE MIL is activated by a fault occurring during TWO CONSECUTIVE “TRIPS”. NO – indicates that the CHECK ENGINE MIL is not activated. OBD SYSTEM READINESS – ENGINE MANAGEMENT If DTC P1000 is flagged after DTCs have been cleared, all engine management OBD diagnostic monitor drive cycles HAVE NOT BEEN COMPLETED. If DTC P1111 is flagged after DTCs have been cleared, all engine management OBD diagnostic monitor drive cycles HAVE BEEN COMPLETED. OBD SYSTEM READINESS – TRANSMISSION Use WDS Datalogger “TOTAL NUMBER OF DTC SET” to determine if transmission OBD monitoring has been completed. Refer to page 7. OBD DIAGNOSTIC MONITORS The Engine Management and Transmission Control systems are continuously checked during vehicle operation by the Engine Control Module (ECM) and Transmission Control Module (TCM) on-board diagnostic (OBD) facilities. Powertrain OBD incorporates six diagnostic monitors. Each monitor has an associated group of DTCs. The diagnostic monitors will complete the diagnostic test(s) if a specified service “drive cycle” is carried out. The six diagnostic monitors are as follows: – – – – – – Heated Oxygen Sensors Monitor Adaptive Fuel Monitor Misfire Monitor Catalyst Efficiency Monitor Evaporative System Monitor Comprehensive Component Monitor (Engine Management / Transmission)

Code 13 36CU DTC FF13 PCMF MAP SENSOR SIGNAL This DTC looks for a fluctuating vacuum signal during starting and monitors vacuum ‘V’ throttle position when the engine is running. Code 14 36CU DTC FF14 ENGINE COOLANT TEMPERATURE SENSOR (ECTS) CIRCUIT This DTC looks for the ETCS signal voltage out of range or static during engine warm-up. Code 16 36CU DTC FF16 INTAKE AIR TEMPERATURE SENSOR (IATS) CIRCUIT This DTC looks for the IATS out of range. Code 17 3GCU DTC FF17 THROTTLE POSITION SENSOR (TPS) CIRCUIT This DTC looks for the TPS signal voltage out of range. Code 18 36CU DTC FF18 AND FF19 THROTTLE POSITION SENSOR (TPS) CALIBRATION DTC FF18. This DTC looks for low TPS signal voltage at high load (MAP). DTC FF19. This DTC looks for high TPS signal voltage at low load (MAP). 36CU DTC FF18 AND FF19 THROTTLE POSITION SENSOR (TPS) CALIBRATION DTC FF18. This DTC looks for low TPS signal voltage at high load (MAP). DTC FF19. This DTC looks for high TPS signal voltage at low load (MAP).

Circuit Description The inflatable restraint steering wheel module deployment loop consists of a steering wheel module, steering wheel module coil, steering wheel module high control, and steering wheel module low control circuits. Shorting bars are used on the steering wheel module connector as well as the steering wheel module coil connector which will short together the steering wheel module high and steering wheel module low control circuits when the connector is disconnected. This will help to prevent unwanted deployment of the inflator module during servicing. When the ignition is turned ON, the inflatable restraint sensing and diagnostic module (SDM) performs continuous diagnostic tests on the deployment loops to check for proper circuit continuity and for shorts to ground or voltage. If a malfunction is detected, a DTC will be stored in memory. DTC Descriptors This diagnostic procedure supports the following DTCs: • DTC B0022 Driver Frontal Deployment Loop Resistance Low • DTC B0024 Driver Frontal Deployment Loop Voltage Out of Range • DTC B0026 Driver Frontal Deployment Loop Open Conditions for Running the DTC Ignition 1 voltage is within the normal operating voltage range. Conditions for Setting the DTC • DTC B0022 will set when the steering wheel module deployment loop resistance is less than 1.3 ohms for 500 milliseconds. • DTC B0024 will set when one of the following conditions occurs: – The SDM detects the voltage at steering wheel module high control is shorted to ground or voltage for 500 milliseconds. – The SDM detects the voltage at steering wheel module high control is less than 2.4 volts and steering wheel module deployment loop resistance is less than 6 ohms for 500 milliseconds. • DTC B0026 will set when one of the following conditions occurs: – The SDM detects the steering wheel module deployment loop resistance is greater than 4.8 ohms for 500 milliseconds. – The SDM detects the voltage at steering wheel module high control is less than 2.4 volts and steering wheel module deployment loop resistance is 6 ohms or greater for 500 milliseconds. Action Taken When the DTC Sets The SDM commands the AIR BAG indicator ON via class 2 serial data.

ISSUE SERVICE TIP
This TSB article is a diagnostic procedure to address vehicles that exhibit lean driveability MASS AIR FLOW (MAF) DISCUSSION symptoms and may or may not have any Diagnostic MAF sensors can get contaminated from a variety Trouble Codes (DTCs) stored in memory. of sources: dirt, oil, silicon, spider webs, potting
compound from the sensor itself, etc. When a MAF sensor gets contaminated, it skews the transfer Follow the diagnostic procedures described in the function such that the sensor over-estimates air flow following Service Tip. The revised diagnostic at idle (causes the fuel system to go rich) and procedure is a more accurate means of diagnosing under-estimates air flow at high air flows (causes
the symptoms. fuel system to go lean). This means Long Term Fuel Trims will learn lean (negative) corrections at idle and learn rich (positive) corrections at higher air flows.
